     BACKGROUND 
     A load control system may include one or more electrical loads that a user may wish to control via a single load control device. These electrical loads may include, for example, lighting loads, HVAC units, motorized window treatment or projection screens, humidity control units, audio systems or amplifiers, Internet of Things (IoT) devices, and/or the like. The electrical loads may have advanced features. For example, a lighting load may be controlled to emit light of varying intensities and/or colors in response to a user command. The amount of power delivered to the electrical loads may be adjusted to an absolute level or by a relative amount. Multiple electrical loads may be manipulated such that one or more presets or scenes (e.g., combinations of particular lighting conditions, temperature settings, speaker volume, and/or the like) may be created, and a user may desire the ability to browse through the presets or scenes, and activate one that fits a particular occasion. With a traditional load control device such as a mechanical toggle switch, a user will not able to perform any of the aforementioned functions, let alone performing multiple of them through one device. 
     The insufficiencies of traditional load control devices arise at least in part from the actuation mechanism utilized in those devices. More specifically, traditional load control devices are typically only capable of responding to simple user actions such as moving a lever or pushing a button. As such, the number and/or types of control that may be applied through a load control device is limited. To meet the demand of advanced electrical loads, there is a need to employ alternative user interface technologies such as those capable of detecting human gestures and translating the gestures into control data (e.g., control signals) for controlling the electrical loads. These technologies may expand the capacity of a load control device, while at the same time enhancing its usability and aesthetic appeal, for example. 
     A traditional load control device may also lack the capacity to provide visual feedback to a user about the operation of the load control device and/or the electrical loads controlled by the load control devices. Such capacity is an important aspect of user experience in an advanced load control system where a user may be able to manipulate multiple operating parameters of an electrical load or to control multiple electrical loads via a single control device. Provision of feedback in those environments can keep the user informed about the state and/or mode of the control device and electrical loads, and may help the user navigate through the various functionalities of the control device. 
     SUMMARY 
     As described herein, a control device configured for use in a load control system to control one or more electrical loads external to the control device may comprise an actuation member having a front surface defining a touch sensitive surface (e.g., capacitive touch surface) configured to detect a touch actuation (e.g., a point actuation) along at least a portion of the front surface. The control device may include a main printed circuit board (PCB) comprising a control circuit, a tactile switch(es), a controllably conductive device, and a drive circuit operatively coupled to a control input of the controllably conductive device for rendering the controllably conductive device conductive or non-conductive to control the amount of power delivered to the electrical load. The control device may also include a capacitive touch PCB affixed to the actuation member. The capacitive touch PCB may comprise a touch sensitive circuit comprising one or more receiving capacitive touch pads located on the capacitive touch PCB, behind the actuation member, and arranged in a linear array adjacent to the capacitive touch surface. The capacitive touch PCB may include a ground plane on a back side of the capacitive touch PCB. The actuation member may be configured to pivot about a pivot axis to actuate the tactile switch on the main PCB in response to actuations of the actuation member, such that the capacitive touch surface and the capacitive touch PCB are configured to move with the actuation member in response to actuations of the actuation member. The actuation member may additionally be configured to substantially maintain its position (e.g., not pivot about the pivot axis) in response to a user input applied over the pivot axis so that the tactile switch is not actuated by the user input. In response to such a user input, the control device may enter a programming mode to allow a user to configure or adjust the operating characteristics of the control device. The control device may also be configured to perform a specific operation (e.g., switch from an intensity control mode to a color control mode) in response to the user input. 
     A control device may include an actuation member, a main printed circuit board, and/or a capacitive touch printed circuit board affixed to the actuation member. The actuation member has a front surface that may define a touch sensitive surface (e.g. capacitive touch surface) that is configured to detect a touch actuation along at least a portion of the touch sensitive surface (e.g., a portion above a light bar of the control device). The main printed circuit board may include a first control circuit, a tactile switch, a controllably conductive device, and/or a drive circuit. The drive circuit is operatively coupled to a control input of the controllably conductive device for rendering the controllably conductive device conductive or non-conductive to control the amount of power delivered to the electrical load. The actuation member may be configured to pivot about a pivot axis to actuate the tactile switch on the main printed circuit board in response to tactile actuations of the actuation member. 
     The capacitive touch printed circuit board may include one or more receiving touch sensitive pads, such as capacitive touch pads, located on the capacitive touch printed circuit board. The touch sensitive pads may be located behind the actuation member and/or may be arranged in a linear array adjacent to the touch sensitive surface. The capacitive touch printed circuit board may also include a second control circuit configured to receive inputs from the capacitive touch pads and provide an output signal to the first control circuit in response to the inputs received from the capacitive touch pads. The capacitive touch printed circuit board may be configured to move with the actuation member in response to tactile actuations of the actuation member. The first control circuit may be configured to control an amount of power delivered to the electrical load in response to a position of a touch actuation along the length of the touch sensitive surface indicated by the output signal from the second control circuit. 
     The capacitive touch printed circuit board further comprising a proximity pad, which for example, may extend parallel to the linear array of receiving capacitive touch pads and/or be located farther away from the touch sensitive surface than the linear array of receiving capacitive touch pads. The second control circuit is configured to ignore the inputs received from receiving capacitive touch pads in response to receiving an input from the proximity pad. 
     The second control circuit may be configured to compare a measured voltage provided via a capacitive touch pad to a voltage threshold and generate an output signal that indicates when the measured voltage exceeds the voltage threshold. The second control circuit may be configured to use different voltage thresholds for different capacitive touch pads. For example, the receiving capacitive touch pads may be separated from the capacitive touch surface by varying distances, and the different voltage thresholds may be used based on the distance between the capacitive touch pad and the capacitive touch surface. 
     The first control circuit may be configured to not respond to (e.g., ignore) output signals received via the capacitive touch surface during times when the controllably conductive device is rendered conductive and/or during time when transmitting or receiving wired or wireless communications via a communication circuit of the control device. 
     The first control circuit may be configured operate in one of a plurality of touch actuation modes. For example, when the lighting load is off, the first control circuit may be configured to operate in a first touch actuation mode and configured to turn the electrical load on in response to a touch actuation of the touch sensitive surface. Further, and for example, when the lighting load is off, the first control circuit may be configured to operate in a second touch actuation mode and the first configure circuit is not configured to turn the electrical load on in response to a touch actuation of the touch sensitive surface. 
     The first control circuit configured to detect a touch actuation applied to the area of the front surface of the actuation member that is characterized by limiting pivoting for a predetermined period of time, and enter an advanced programming mode in response to the detection of the user input applied the area of the front surface characterized by limiting pivoting. 
     In some examples, the first control circuit configured to ignore output signals received from the second control circuit when the electrical load is off. For example, when the electrical load is off, the first control circuit may be configured to ignore inputs from the touch sensitive device in response to touch actuations that are above a position along the touch sensitive actuator that corresponds to the predetermined level, and may be configured to respond to inputs from the touch sensitive device in response to touch actuations that are below the position along the touch sensitive actuator that corresponds to the predetermined level. 
     The first control circuit may be configured to prioritize inputs received in response to tactile actuation of the actuation member over the output signals received from the second control circuit by ignoring the output signals when a tactile actuation of the tactile switch is received within a blanking period after an initial detection of the touch actuation along the touch sensitive surface. 
     The first control circuit may be configured to determine that the position of the touch actuation on the touch sensitive surface is maintained for an amount of time that is shorter than the blanking period without detecting a tactile actuation of the actuation member, and the control device may be configured to turn on the electrical load to a power level associated with the position of the touch actuation along the length of the touch sensitive surface. 
     The first control circuit may be configured to start a blanking period in response to a tactile actuation of the actuation member to turn on or off the electrical load, and ignore output signals received from the second control circuit during the blanking period. 
     A control device may include an actuation member, a touch sensitive device, and a control circuit. The actuation member may have a front surface defining a touch sensitive surface along at least a portion of the front surface. The actuation member may be configured to move in response to a tactile actuation of the actuation member. The touch sensitive device may be configured to detect a touch actuation along the touch sensitive surface. The control circuit may be configured to determine a position of the touch actuation along the length of the touch sensitive surface in response to the touch actuation along the touch sensitive surface. The control circuit may be configured to determine a position of the touch actuation along the length of the touch sensitive surface in response to the touch actuation along the touch sensitive surface, turn the electrical load on or off in response to an actuation of the tactile switch, and control an amount of power delivered to the electrical load based on inputs received from the touch sensitive device 
     In some examples, the control circuit may be configured to prioritize inputs received in response to tactile actuations of the actuation member over the inputs received from the touch sensitive device in response to touch actuations of the touch sensitive surface. For example, the control circuit may be configured to prioritize inputs received in response to tactile actuation of the actuation member over the inputs received from the touch sensitive device in response to touch actuations of the touch sensitive surface by ignoring inputs received from the touch sensitive device when a tactile actuation is received within a blanking period after an initial detection of the touch actuation along the touch sensitive surface. 
     In some examples, the control circuit may be configured to start a blanking period in response to a tactile actuation of the actuation member to turn on or off the electrical load, and ignore inputs received from the touch sensitive device in response to touch actuations of the touch sensitive surface during the blanking period. 
     In some examples, the control circuit may be configured to ignore inputs from the touch sensitive device in response to touch actuations along at least a portion of the touch sensitive surface when the electrical load is off. 
     In some examples, when the electrical load is off, the control circuit may be configured to ignore inputs from the touch sensitive device in response to touch actuations of the touch sensitive surface that last for less than a predetermined period of time. Further, the control circuit may be configured to determine that a position of a touch actuation along the touch sensitive surface is maintained for the predetermined period of time while the electrical load is off, and may be configured to turn the electrical load on to a power level associated with the position in response to the actuation of the tactile switch. 
     In some examples, the actuation member may include an upper portion and a lower portion, and may be configured to pivot around a pivot axis in response to a tactile actuation of the upper portion or the lower portion. In such examples, the actuation member may be configured to substantially maintain its position with respect to the base portion in response to a user input applied via an area of the front surface proximate to the pivot axis that is characterized by limited pivoting. The control circuit may be configured to detect a touch actuation applied to the area of the front surface characterized by limiting pivoting for a predetermined period of time, and may be configured to change an operating mode of the control device or control the electrical load in response to the detection of the user input applied the area of the front surface characterized by limiting pivoting. Alternatively or additionally, the control circuit may be configured to change an operating mode of the control device in response to detecting the touch actuation applied over the pivot axis, where the operating mode allows a user of the control device to adjust an operating characteristic of the control device. 
     In some examples, the actuation member may be supported by a base portion and may be configured to actuate a first tactile switch in response to a tactile actuation of an upper portion and actuate a second tactile switch in response to a tactile actuation of a lower portion. The touch sensitive surface (e.g., and control circuit) may be configured to detect a user input applied to an area of the touch sensitive area located approximately half-way between the first and second tactile switches. The control circuit may be configured to change an operating mode in response to detecting the user input in the area of the touch sensitive surface, where the operating mode allows a user of the control device to adjust an operating characteristic of the control device. 
     In some examples, the touch sensitive device may include a plurality of touch elements (e.g., such as capacitive touch elements). The distance between the front surface of the actuation member and the plurality of touch elements may not be not uniform. For example, the distance may be shorter in the middle of the actuation member and longer towards the top and/or bottom of the actuation member. Or, the distance may be shortest at the top and longest at the bottom, or vice versa. The touch sensitive device may be configured to use different sensitivities, such as different thresholds (e.g., voltage thresholds) when detecting touch actuations along the different touch elements (e.g., to detect the position of a touch actuation along the touch surface). 
     In some examples, the control circuit may be configured to not respond to the output signal during times when the controllably conductive device is rendered conductive and/or during times when transmitting or receiving wired or wireless communications via a communication circuit of the control device. 
     In some examples, the control circuit may be configured to prioritize inputs received in response to tactile actuation of the actuation member over the inputs received from the touch sensitive device in response to touch actuations of the touch sensitive surface by ignoring inputs received from the touch sensitive device when a tactile actuation is received within a blanking period after an initial detection of the touch actuation along the touch sensitive surface.

     DETAILED DESCRIPTION 
       FIG.  1    is a simplified block diagram of an example load control system. As shown, the load control system is configured as a lighting control system  100  for control of one or more lighting loads, such as a lighting load  102  that is installed in a ceiling-mounted downlight fixture  103  and a controllable lighting load  104  that is installed in a table lamp  105 . The lighting loads  102 ,  104  shown in  FIG.  1    may include light sources of different types (e.g., incandescent lamps, fluorescent lamps, and/or LED light sources). The lighting loads may have advanced features. For example, the lighting loads may be controlled to emit light of varying intensities and/or colors in response to a user command. The amount of power delivered to the lighting loads may be adjusted to an absolute level or by a relative amount. The lighting control system  100  may be configured to control one or more of the lighting loads (e.g., and/or other electrical loads) according to one or more configurable presets or scenes. These presets or scenes may correspond to, for example, predefined light intensities and/or colors, predefined entertainment settings such as music selection and/or volume settings, predefined window treatment settings such as positions of shades, predefined environmental settings such as HVAC settings, or any combination thereof. The presets or scenes may correspond to one or more specific electrical loads (e.g., bedside lamps, ceiling lights, etc.) and/or one or more specific locations (e.g., a room, an entire house, etc.). 
     The lighting load  102  may be an example of a lighting load that is wired into a power control and/or delivery path of the lighting control system  100 . As such, the lighting load  102  may be controllable by a wall-mounted control device such as a dimmer switch. The lighting load  104  may be an example of a lighting load that is equipped with integral load control circuitry and/or wireless communication capabilities such that the lighting load may be controlled via a wireless control mechanism (e.g., by a remote control device). 
     The lighting control system  100  may include one or more control devices for controlling the lighting loads  102 ,  104  (e.g., controlling an amount of power delivered to the lighting loads). The lighting loads  102 ,  104  may be controlled substantially in unison, or be controlled individually. For example, the lighting loads may be zoned so that the lighting load  102  may be controlled by a first control device, while the lighting load  104  may be controlled by a second control device. The control devices may be configured to turn the lighting loads  102 ,  104  on and off. The control devices may be configured to control the magnitude of a load current conducted through the lighting loads (e.g., so as to control an intensity level of the lighting loads  102 ,  104  between a low-end intensity level L LE  and a high-end intensity level L HE ). The control devices may be configured to control an amount of power delivered to the lighting loads to an absolute level (e.g., to a maximum allowable amount), or by a relative amount (e.g., an increase of 10% from a current level). The control devices may be configured to control a color of the lighting load  102 ,  104  (e.g., by controlling a color temperature of the lighting loads or by applying full color control over the lighting loads). 
     The control devices may be configured to activate a preset associated with the lighting load  102 ,  104 . A preset may be associated with one or more predetermined settings of the lighting loads, such as an intensity level of the lighting loads and/or a color of the lighting loads. The presets may be configured via the control device and/or via an external device (e.g., a mobile device) by way of a wireless communication circuit of the control device. The control devices may be configured to activate control of a zone. A zone may correspond to one or more electrical loads that are configured to be controlled by the control devices. A zone may be associated with a specific location (e.g., a living room) or multiple locations (e.g., an entire house with multiple rooms and hallways). The control devices may be configured to switch between different operational modes. An operational mode may be associated with controlling different types of electrical loads or different operational aspects of one or more electrical loads. Examples of operational modes may include a lighting control mode for controlling one or more lighting loads (e.g., which in turn may include a color control mode and an intensity control mode), an entertainment system control mode (e.g., for controlling music selection and/or the volume of an audio system), an HVAC system control mode, a winter treatment device control mode (e.g., for controlling one or more shades), and/or the like. 
     One or more characteristics of the control device and/or the lighting load  102 ,  104  described herein may be customized via an advanced programming mode (APM). Such characteristics may include, for example, an intensity level associated with a preset, a fade-on/fade-off time, enablement/disablement of visual indicators, a low-end trim (e.g., a minimum intensity level to which the lighting load  102 ,  104  may be set by the control device), a high-end trim (e.g., a maximum intensity level to which the lighting load  102 ,  104  may be set by the control device), and/or the like. Examples of an advanced programming mode for a wall-mounted load control device can be found in U.S. Pat. No. 7,190,125, issued Mar. 13, 2007, entitled PROGRAMMABLE WALLBOX DIMMER, the entire disclosure of which is hereby incorporated by reference. The control device may be manipulated to enter the advanced programming mode in various ways. For instance, the control device may be moved into the advanced programming mode via a press-and-hold or a double-tap applied to a front area of the control device. Ways to activate the advanced programming mode for a control device will be described in greater detail below. 
     The control device described herein may be, for example, a dimmer switch  110 , a retrofit remote control device  112 , a wall-mounted remote control device  114 , a tabletop remote control device  116 , and/or a handheld remote control device  118 , as shown in  FIG.  1   . The dimmer switch  110  may be configured to be mounted to a standard electrical wallbox (e.g., via a yoke) and be coupled in series electrical connection between an alternating-current (AC) power source  105  and a lighting load that is wired into the control path of the dimmer switch  110  (e.g., such as the lighting load  102 ). The dimmer switch  110  may receive an AC mains line voltage V AC  from the AC power source  105 , and may generate a control signal for controlling the lighting load  102 . The control signal may be generated via various phase-control techniques (e.g., a forward phase-control dimming technique or a reverse phase-control dimming technique). The dimmer switch  110  may be configured to receive wireless signals (e.g., from a remote control device) representative of commands to control the lighting load  102 , and generate respective control signals for executing the commands. Examples of wall-mounted dimmer switches are described in greater detail in commonly-assigned U.S. Pat. No. 7,242,150, issued Jul. 10, 2007, entitled DIMMER HAVING A POWER SUPPLY MONITORING CIRCUIT; U.S. Pat. No. 7,546,473, issued Jun. 9, 2009, entitled DIMMER HAVING A MICROPROCESSOR CONTROLLED POWER SUPPLY; and U.S. Pat. No. 8,664,881, issued Mar. 4, 2014, entitled TWO-WIRE DIMMER SWITCH FOR LOW-POWER LOADS, the entire disclosures of which are hereby incorporated by reference. 
     The retrofit remote control device  112  may be configured to be mounted to a mechanical switch (e.g., a toggle switch  122 ) that may be pre-existing in the lighting control system  100 . Such a retrofit solution may provide energy savings and/or advanced control features, for example without requiring significant electrical re-wiring and/or without requiring the replacement of existing mechanical switches. As an example, a consumer may replace an existing lamp with the controllable lighting load  104 , switch a toggle switch  122  that is coupled to the lighting load  104  to the on position, install (e.g., mount) the remote control device  112  onto the toggle switch  122 , and associate the remote control device  112  with the lighting source  104 . The retrofit remoted control  112  may then be used to perform advanced functions that the toggle switch  122  may be incapable of performing (e.g., such as dimming the intensity level of the light output, changing the color of the light output, providing feedback to a user, etc.). As shown, the toggle switch  122  is coupled (e.g., via a series electrical connection) between the AC power source  105  and an electrical receptacle  120  into which the lighting load  104  may be plugged (e.g., as shown in  FIG.  1   ). Alternative, the toggle switch  122  may be coupled between the AC power source  105  and one or more of the lighting loads  102 ,  104 , without the electrical receptacle  120 . 
     The wall-mounted remote control device  114  may be configured to be mounted to a standard electrical wallbox and be electrically connected to the AC power source  105  for receiving power. The wall-mounted remote control device  114  may be configured to receive a user input and may generate and transmit a control signal (e.g., control data such as a digital message) for controlling the lighting loads  102 ,  104  in response to the user input. The tabletop remote control device  116  may be configured to be placed on a surface (e.g., an end table or night stand), and may be powered by a direct-current (DC) power source (e.g., a battery or an external DC power supply plugged into an electrical outlet). The tabletop remote control device  116  may be configured to receive a user input, and may generate and transmit a signal (e.g., a digital message) for controlling the lighting loads  102 ,  104  in response to the user input. The handheld remote control device  118  may be sized to fit into a user&#39;s hand, and may be powered by a direct-current (DC) power source (e.g., a battery or an external DC power supply plugged into an electrical outlet). The handheld remote control device  118  may be configured to receive a user input, and may generate and transmit a signal (e.g., a digital message) for controlling the lighting loads  102 ,  104  in response to the user input. Examples of battery-powered remote controls are described in greater detail in commonly assigned U.S. Pat. No. 8,330,638, issued Dec. 11, 2012, entitled “Wireless Battery Powered Remote Control Having Multiple Mounting Means,” and U.S. Pat. No. 7,573,208, issued Aug. 11, 2009, entitled “Method Of Programming A Lighting Preset From A Radio-Frequency Remote Control,” the entire disclosures of which are hereby incorporated by reference. 
     It should be appreciated that, although a lighting control system with two lighting loads is provided as an example above, a load control system as described herein may include more or fewer lighting loads, other types of lighting loads, and/or other types of electrical loads that may be configured to be controlled by the one or more control devices. For example, the load control system may include one or more of: a dimming ballast for driving a gas-discharge lamp; an LED driver for driving an LED light source; a dimming circuit for controlling the intensity level of a lighting load; a screw-in luminaire including a dimmer circuit and an incandescent or halogen lamp; a screw-in luminaire including a ballast and a compact fluorescent lamp; a screw-in luminaire including an LED driver and an LED light source; an electronic switch, controllable circuit breaker, or other switching device for turning an appliance on and off; a plug-in control device, controllable electrical receptacle, or controllable power strip for controlling one or more plug-in loads; a motor control unit for controlling a motor load, such as a ceiling fan or an exhaust fan; a drive unit for controlling a motorized window treatment or a projection screen; one or more motorized interior and/or exterior shutters; a thermostat for a heating and/or cooling system; a temperature control device for controlling a setpoint temperature of a heating, ventilation, and air-conditioning (HVAC) system; an air conditioner; a compressor; an electric baseboard heater controller; a controllable damper; a variable air volume controller; a fresh air intake controller; a ventilation controller; one or more hydraulic valves for use in radiators and radiant heating system; a humidity control unit; a humidifier; a dehumidifier; a water heater; a boiler controller; a pool pump; a refrigerator; a freezer; a television and/or computer monitor; a video camera; an audio system or amplifier; an elevator; a power supply; a generator; an electric charger, such as an electric vehicle charger; an alternative energy controller; and/or the like. 
       FIG.  2    is a perspective view and  FIG.  3    is a front view of an example control device  200  that may be deployed as the dimmer switch  110  and/or the retrofit remote control device  112  in the lighting control system  100 . The control device  200  may comprise a user interface  202  and a faceplate  204 . The control device  200  may be configured to control the amount of power delivered to a lighting load (e.g., turn the lighting load on or off, or adjust the intensity level of the lighting load by transmitting a message for controlling the lighting load via a communication circuit (e.g., a wireless signal via a wireless communication circuit), and/or by controlling the lighting load via an internal load control circuit (e.g., a controllably conductive device of the control device  200 )). The user interface  202  may include a light bar  220  extending along the length of the actuation member. The light bar  220  may be configured to be illuminated by one or more light sources (e.g., one or more LEDs) to visibly display information. When the control device  200  is a wall-mounted dimmer switch, the control device  200  may comprise an enclosure  230  for housing load control circuitry of the dimmer switch. 
     The user interface  202  of the control device  200  may include an actuation member  210  that is configured to be mounted to a base portion  212  (e.g., a bezel). The actuation member  210  may comprise a front surface  214  including an upper portion  216  and a lower portion  218 . The actuation member  210  may be configured to pivot about a pivot axis  222  (e.g., a central axis) in response to a tactile actuation (e.g., a tactile input) of the upper portion  216  and the lower portion  218 . The control device  200  may be configured to control a lighting load of the lighting control system  100  to turn the lighting load on in response to a tactile actuation of the upper portion  216 , and to turn the lighting load off in response to a tactile actuation (e.g., a tactile input) of the lower portion  218  (or vice versa). For example, the control device  200  may be configured to turn the lighting load on to a previous intensity level (e.g., before the lighting load was previously turned off) or to a preset intensity level (e.g., a predetermined or locked preset intensity level) in response to a tactile actuation of the upper portion  216  of the actuation member  210 . The control device  200  may include one or more tactile switches that are actuated in response to the tactile actuations of the upper and/or lower portions  216 ,  218  of the actuation member  210 . 
     The actuation member  210  may also receive user inputs that do not cause the actuation member to pivot (e.g., about the pivot axis  222 ). For example, at least a portion of the front surface  214  of the actuation member  210  may be configured as a touch sensitive surface (e.g., a capacitive touch surface) that is configured to receive (e.g., detect) inputs (e.g., touch actuations/inputs), such as point actuations or gestures, from a user of the control device  200 . The touch sensitive surface of the actuation member  210  may be located adjacent to and/or overlap with the light bar  220 . The actuation member  210  may substantially maintain its position (e.g., with respect to the base portion  212 ) in response to these inputs and, depending on the positions of the inputs, the control device may enter different operating modes and/or carry out different control functions in response. For example, during a normal operating mode of the control device  200 , the front surface  214  of the actuation member  210  may be actuated along the light bar  220  (e.g., along the touch sensitive surface) to adjust the amount of power delivered to, and thus the intensity level of, the lighting load according to the position of the actuation. For instance, the control device  200  may control the magnitude of a load current conducted through the lighting load based on the position of a touch actuation (e.g., a touch input) along the touch sensitive surface of the actuation member  210  to control an intensity level of the lighting load between a low-end intensity level L LE  and a high-end intensity level L HE . The control device  200  may control an amount of power delivered to the lighting load to an absolute level (e.g., to a maximum allowable amount) or by a relative amount (e.g., an increase of 10% from a current level) based on the position of a touch actuation along the touch sensitive surface of the actuation member  210 . Examples of control devices having capacitive touch surfaces are described in greater detail in commonly-assigned U.S. Pat. No. 10,109,181, issued Oct. 23, 2018, entitled GESTURE-BASED CONTROL DEVICE FOR CONTROLLING AN ELECTRICAL LOAD, the entire disclosure of which is hereby incorporated by reference. Although described primarily in context of a capacitive touch surface, it should be appreciated that the control device  200  is not so limited, and in some examples, at least a portion of the front surface  214  of the actuation member  210  may be configured as a different type of touch sensitive surface, such as a resistive touch surface, an inductive touch surface, a surface acoustic wave (SAW) touch surface, an infrared touch surface, acoustic pulse touch surface, or the like. 
     The control device  200  may control the magnitude of a load current conducted through the lighting load based on a single discrete input along the touch sensitive surface and/or based on a plurality of consecutive inputs along the touch sensitive surface. For example, the user may tap their finger at a position along the touch sensitive surface, and in response, the control device  200  may turn the lighting load on to an intensity level based on the position. As an example, if the lighting load is off, the control device  200  may turn the lighting load on to an intensity level based on the position of a touch actuation along the touch sensitive surface of the actuation member  210 . While the lighting load is on, the user may move (e.g., slide) their finger along the touch sensitive surface, and in response, the control device  200  may adjust (e.g., continuously control) the magnitude of the load current conducted through the lighting load based on the positions of a plurality of inputs along the touch sensitive surface. 
     Further, in a color control mode, the control device  200  may control a color of the lighting load based on the position of a touch actuation along the touch sensitive surface of the actuation member  210  (e.g., by controlling a color temperature of the lighting load or by applying full color control over the lighting load). For example, the light bar  220  may be configured to illuminate a spectrum of colors through the length of the light bar  220  (e.g., across the full visible color spectrum, a subset of the visual color spectrum, and/or the light spectrum associated with the color temperatures of a black body radiator). Accordingly, the control device  200  may control the color of the lighting load based on the position of a touch actuation along the touch sensitive surface, and in turn, the corresponding color of that position on the light bar  220 . 
     The control device  200  may be configured to prioritize user inputs that cause the actuation member  210  to pivot over user inputs that do not cause the actuation member  210  to pivot, or vice versa. For example, when the lighting load is off and a user moves a finger close to the upper portion  216  of the actuation member  210  causing the control device  200  to detect a touch actuation via the touch sensitive surface (e.g., along the light bar  220 ), the control device  200  may temporarily delay responding to the touch actuations received via the touch sensitive surface to see if a user is attempting to actuation the upper portion  216  of the actuation member  210  to turn on the lighting load. Accordingly, the control device  200  may avoid turning on the lighting load to an intensity level based on the position of the actuation on the light bar  220  (e.g., in response to the touch sensitive surface) if the user&#39;s finger happens to sweep past the light bar  220  while actuating the upper portion  216  of the actuation member  210  or if the user&#39;s finger actuates the upper portion  216  of the actuation member  210  too close to the light bar  220 . In addition, when the lighting load is on and a user moves a finger close to the lower portion  218  of the actuation member  210  causing the control device  200  to detect a touch actuation via the touch sensitive surface, the control device  200  may temporarily ignore the touch actuations received via the touch sensitive surface after the actuation of the lower portion  218 . Accordingly, the control device  200  may avoid turning on the lighting load again if the user&#39;s finger happens to sweep past the light bar  220  while moving away from the lower portion  218  of the actuation member  210 . 
     The control device  200  may, for example, be configured to prioritize inputs received in response to actuation of the actuation member  210  over the inputs received via the capacitive touch surface by ignoring inputs received via the capacitive touch surface when a tactile actuation of the actuation member  210  is received within a blanking period (e.g., a first blanking period or an after-touch blanking period) after an initial detection of a touch actuation received via the capacitive touch surface. For example, the blanking period may be approximately 200 milliseconds. The blanking period may occur after (e.g., in response to) a touch actuation (e.g., the initial detection of a touch actuation). That is, the control device  200  may ignore touch actuations received via the capacitive touch surface when a touch actuation of the actuation member  210  is received within the blanking period (e.g., a touch actuation that begins during the blanking period). For instance, in some examples, the control device  200  may start the blanking period (e.g., a timer) in response to receiving a touch actuation via the capacitive touch surface, and ignore touch actuations received via the capacitive touch surface during the blanking period if the control device  200  receives a touch actuation of the actuation member  210  during the blanking period (e.g., a touch actuation begins during the blanking period). As such, the control device  200  may prioritize user inputs that cause the actuation member  210  to pivot over user inputs that do not cause the actuation member  210  to pivot during the blanking period. 
     Further, even if a blanking period is implemented, the control device  200  may be configured to respond to a quick “tap” along the touch sensitive surface. For instance, the control device  200  may be configured to determine that a touch actuation is at a position on the touch sensitive surface for an amount of time that is shorter than the blanking period without the actuation member  210  being actuated (e.g., a touch actuation starts and finishes before the end of the blanking period) and, in response, turn the lighting load on to an intensity level associated with the position in response to the touch actuation. Accordingly, the control device  200  may both implement the blanking period to avoid unintentional touch actuations along the touch sensitive surface and still respond quickly to intentional touch actuations along the touch sensitive surface. 
     The control device  200  may be configured to turn the lighting load on in response to a touch actuation received via the touch sensitive surface even when implementing the blanking period. For example, the control device  200  may be configured to receive a touch actuation via the touch sensitive surface at a position for an amount of time that is greater than the blanking period without the tactile switch being actuated (e.g., a touch actuation begins during the blanking period and ends after the blanking period) and, in response, turn the lighting load on to an intensity level associated with the position in response to the touch actuation. Further, the control device  200  may adjust the length of a blanking period, for example, through a user input (e.g., a touch actuation and/or a tactile actuation) received while in the advanced programming mode. For instance, in some examples, the blanking period may be configured to be greater than one second (e.g., multiple seconds). In such examples, the control device  200  may respond to a press-and-hold touch actuation along the light bar  220  by turning the lighting load on to an intensity level associated with the position of the press-and-hold actuation. 
     The control device  200  may be configured to temporarily ignore inputs received via the capacitive touch surface after a tactile actuation of the actuation member  210  that causes the lighting load to turn on or off. The control device  200  may be configured in this manner to, for example, avoid mistakenly turning the lighting load back on and/or adjusting the power delivered to (e.g., the intensity level of) the lighting load after a tactile actuation of the actuation member  210 . For example, the control device  200  may be configured to ignore inputs received via the capacitive touch surface during a blanking period (e.g., a second blanking period or after-tactile period) after detecting a tactile actuation of the actuation member to turn the lighting load on or off. For instance, in some example, the control device  200  may start the blanking period in response to turning on or off the lighting load and, during the blanking period, ignore inputs received via the capacitive touch surface during the blanking period. As such, through the use of the blanking period, the control device  200  may be able avoid unintentional touch actuations along the capacitive touch surface after a tactile actuation of the actuation member  210 . In sum, the control device  200  may be configured with one or more blanking periods, such as a first blanking period that is used to avoid unintentional touch actuations after an initial detection of a touch actuation received via the capacitive touch surface and prior to tactile actuations of the actuation member  210  (e.g., a blanking period that occurs after (e.g., in response to) a touch actuation), and/or a second blanking period that is used to avoid unintentional touch actuations after tactile actuations of the actuation member  210  (e.g., a blanking period that occurs after (e.g., in response to) a tactile actuation). 
     The control device  200  may be configured to detect that a touch actuation is received at a position of the touch sensitive surface that is defined by limited pivoting (e.g., a tactile actuation that causes the actuation member  210  to substantially maintain its position with respect to the base portion  212 ) and, in response, change an operating mode of the control device  200  and/or control a lighting load. One example of a position that is defined by limited pivoting is an area  215  of the front surface  214  over the pivot axis  222 . The touch actuation (e.g., a touch input) being detected by the control device  200  may comprise a press-and-hold actuation (e.g., pressing and holding a finger in the area  215  for a non-transitory time period, such as a few seconds), a double-tap actuation (e.g., two transitory actuations of the area  215  executed in quick succession), a swipe gesture (e.g., consecutive contacts with multiple positions of the area  215  within a brief time period), and/or the like. Since the touch actuation is applied to the area  215  over the pivot axis  222  of the actuation member  210 , the touch actuation may not cause the actuation member  210  to pivot (e.g., about the pivot axis  222 ) or otherwise change its position with respect to the base portion. As such, the touch actuation applied over the pivot axis  222  may be clearly distinguished from a tactile actuation of the upper portion  216  or the lower portion  218  so as to prevent accidental triggering of a control function that is associated with the tactile actuation of the upper portion  216  or the lower portion  218 . It should be noted that although the description is provided herein in the context of a control device having a central pivot axis, the proposed techniques can also be used with other types of control devices including those configured to pivot about an axis located at a top or bottom end of the control device. That is, although illustrated at approximately the midpoint of the actuation member  210 , the area  215  and/or the pivot axis  222  may be located elsewhere on the actuation member  210 , such as closer to the upper portion  216  or the lower portion  218  of the actuation member  210 . 
     The control device  200  may turn the lighting load on or off in response to receiving a touch actuation at a position of the touch sensitive surface that is defined by limiting pivoting. Further, the control device  200  may change an operating mode of the control device  200  in response to receiving a touch actuation at a position of the touch sensitive surface that is defined by limiting pivoting. One example of a change in operating mode is a change between an intensity control mode and a color control mode (e.g., a color temperature control mode and/or a full color spectrum control mode). Another example of a change in operating mode is a change between a normal operating mode and a commissioning mode that is used to associate the control device  200  with an electrical load. Yet another example of a change in operating mode is a change between a normal operating mode to an advanced programming mode. As described herein, an advanced programming mode may allow configuration and/or adjustment of one or more operating characteristics of the control device and/or a lighting load of the lighting control system  100 , such as a low-end trim (e.g., a minimum intensity level) and/or a high-end trim (e.g., a maximum intensity level) of the lighting load. 
     During an advanced programming mode as described herein, the front surface  214  of the actuation member  210  may be actuated along the light bar  220  (e.g., a touch actuation on the touch sensitive surface) to adjust an operating characteristic (e.g., such as a low-end trim) of the control device. The light bar  220  may be affixed to the actuation member  210 , and as such, the light bar  220  may be configured to move when the actuation member  210  pivots. An example of a control device having an advanced programming mode is described in greater detail in commonly-assigned U.S. Pat. No. 7,190,125, issued Mar. 13, 2007, entitled PROGRAMMABLE WALLBOX DIMMER, the entire disclosure of which is hereby incorporated by reference. 
     The user may set (e.g., store) a locked preset intensity level when in the advanced programming mode. A locked preset intensity level may be a programmable intensity level setting to which the control device will turn on a lighting load on in response to a tactile actuation of the actuation member  210  that turns on the lighting load (e.g., a tactile actuation of the upper portion  214  of the actuation member  210 ), regardless of the intensity level the lighting load was set to when it was last turned off. Once the control device  200  has entered the advanced programming mode (e.g., by pulling out a service switch, such as an air-gap actuator as shown in  FIG.  2   , possibly in combination with other actuations), the control device  200  may allow the user to select between different characteristics to adjust, such as the locked preset intensity level. Once the user selects the locked preset intensity level for configuration, the control device  200  may indicate that the locked present intensity level configuration has been initiated (e.g., by flashing the internal light sources). Next, the control device  200  may receive a touch actuation from the user via the touch sensitive surface (e.g., a point actuation along the light bar  220 ) that corresponds with an intensity level, and in response, the control device  200  will set the locked preset intensity level based on that touch actuation. Finally, the user may exit the advanced programming mode. Thereafter, whenever the control device  200  receives a tactile actuation to turn the lighting load on, the control device  200  will turn the lighting load on to the locked preset intensity level. 
     Further, through the advanced programming mode, the control device  200  may be configured to use an unlocked preset intensity level. When using the unlocked preset intensity level, the control device  200  may be configured to turn the lighting load on to the intensity level that was set when the lighting load was last turned off (e.g., a previous intensity level). When using the unlocked preset light level and when the lighting load is off, the control device  200  may illuminate one internal light source (e.g., and/or a portion of the light bar  220 ) to a greater intensity than the rest to indicate the unlocked preset intensity level to the user. 
     The control device  200  may be configured to ignore touch actuations via the touch sensitive surface when the lighting load is off (e.g., disable the capacitive touch circuit when the lighting load is off). For example, the control device  200  may ignore touch actuations received via the touch sensitive surface for as long as the lighting load is off, and may turn on the lighting load in response to tactile actuations of the upper portion  216  of the actuation member  210 . However, in some instances, the control device  200  may turn on the lighting load in response to special touch inputs, such as long press-and-hold actuations (e.g., touch actuations that exceed a predetermined period of time) or a double-tap touch actuations. Further, the control device  200  may ignore touch actuations received via the touch sensitive surface during a blanking period after detecting a tactile actuation of the tactile switch to turn the lighting load on, and respond to touch actuations received via the touch sensitive surface after the blanking period. 
     Further, in some examples, and prior to turning on the lighting load, the control device  200  may be configured to allow a user to adjust an intensity level for turning on the lighting load through a touch actuation received via the capacitive touch surface. For instance, the control device  200  may be configured to receive a touch actuation via the capacitive touch surface while the lighting load is in an off state, and in response, adjust the turn-on intensity level of the lighting load but not actually turn on the lighting load. Then, upon a subsequent actuation of the actuation member  210 , the control device  200  may turn the lighting load on to the turn-on intensity level that was set while the lighting load was in the off state. 
     The control device  200  may be configured to set a locked preset power level (e.g., intensity level) for the lighting load, such that the control device  200  is configured to automatically turn the lighting load on to the locked intensity level during a subsequent turn on event. For example, if the control device  200  is configured with a locked intensity level of 20% and the lighting load is in an off state, the control device  200  may be configured to turn the lighting load on to a 20% intensity level in response to a tactile actuation of the actuation member  210 , for example, regardless of whether the user contacts the touch sensitive surface while actuating the actuation member  210 . This locked preset intensity level may be configured by the user, for example, through an advanced programming mode of the control device  200 . 
     The control device  200  may be configured to determine whether to ignore a touch actuation received via the touch sensitive surface based on the position of the touch actuation along the touch sensitive surface. That is, the control device  200  may be configured to respond to touch actuations received on some positions and ignore touch actuations received on other positions of the touch sensitive surface. For example, the control device  200  may be configured to only respond to touch actuations that are received via the touch sensitive surface when those touch actuations are received at a position that is associated with an intensity level that is less than the default intensity level (e.g., the default intensity level being the intensity level to which the control device  200  would turn on the lighting load in response to a tactile actuation of the actuation member  210 , such as a locked present intensity level, a previous intensity level, and/or a turn-on intensity level). Such a feature may be helpful if the control device  200  controls a lighting load used in a hallway or bathroom to ensure that the lighting load does not turn on to an intensity level that would disrupt the user (e.g., be too bright for the user in the middle of the night). Further, in some examples, the control device  200  may also take into consideration the time when the touch actuation is received. As such, the control device  200  may determine whether to ignore a touch actuation received via the touch sensitive surface based on the position of the touch actuation along the touch sensitive surface and the time of day and/or day of the week (e.g., the control device  200  may ignore touch actuation at positions that correspond to certain intensity levels at nighttime). 
     The control device  200  may be configured to operate in one or more touch actuation modes (e.g., capacitive touch modes). The control device  200  may be configured to operate in a similar manner as different dimmer switches, for example, smart dimmer switches (e.g., processor-controlled dimmer switches) when in a first touch actuation mode (e.g., a smart-dimmer mode) and traditional dimmer switches (e.g., analog dimmers and/or non-smart dimmers) when operating in a second touch actuation mode (e.g., a traditional-dimmer mode). In the first touch actuation mode, the control device  200  may be configured to turn on the lighting load in response to (e.g., respond to) touch actuations via the capacitive touch surface when the lighting load is off (e.g., enable the capacitive touch circuit when the lighting load is off). In the second touch actuation mode, the control device  200  may not be configured to turn on the lighting load in response to (e.g., ignore) touch actuations via the capacitive touch surface when the lighting load is off (e.g., disable the capacitive touch circuit when the lighting load is off). In addition, the control device  200  may be configured to adjust the turn-on intensity level of the lighting load (e.g., to which the lighting load will be turn on in response to a subsequent tactile actuation of the actuation member  210 ) when operating in the second touch actuation mode. Further, the control device  200  may be configured with different operating characteristics (e.g., the number and/or the length of blanking periods, the types and/or characteristics of filtering modes, etc.) when operating in the first touch actuation mode as compared to the second actuation mode. 
     The control device  200  may be configured to change between the first and second touch actuation modes. For example, the control device  200  may select one of the touch actuation modes based on a user input (e.g., a touch actuation and/or a tactile actuation) received while in an advanced programming mode. In addition, the control device  200  may select (e.g., automatically select) one of the touch actuation modes in response the selection of another operating characteristic in the advance programming mode. For example, the control device  200  may be configured to operate in the first touch actuation mode when a locked preset intensity level is not set and in the second touch actuation mode when a locked preset intensity level is set (e.g., via the advanced programming mode). 
     In addition, the control device  200  may be configured to operate in additional touch actuation modes. For example, in another touch actuation mode, the control device  200  may be configured to turn on the lighting load in response to (e.g., respond to) touch actuations when the lighting load is off and the position of the touch actuation is below a position along the capacitive touch surface associated with the locked present intensity level. In addition, the control device  200  may not be configured to turn on the lighting load in response to (e.g., ignore) touch actuation when the lighting load is off and the position of the touch actuation is above the position along the capacitive touch surface associated with the locked present intensity level. 
     The control device  200  may be configured to change operating characteristics (e.g., the number and/or the length of blanking periods, the types and/or characteristics of filtering modes, etc.) and/or the operating mode of the control device  200  (e.g., intensity control mode, color control mode, advanced programming mode, commissioning mode, etc.) in a variety of manners. For example, the control device  200  may change operating characteristics and/or operating mode through the use of the advance programming mode, in response to receiving a touch actuation at a position of the touch sensitive surface that is defined by limiting pivoting (e.g., the area  215 ), based on the time of day and/or day of the week (e.g., time clock information), and/or based on a learning algorithm. For instance, once in the advanced programming mode, the control device  200  may be configured to change between operating modes (e.g., intensity control mode and color control mode) and/or change an operating characteristics (e.g., the number and/or the length of blanking periods, the types and/or characteristics of filtering modes, etc.). Alternatively or additionally, the control device  200  may change between operating modes and/or change an operating characteristics in response to receiving an input at a position of the touch sensitive surface that is defined by limiting pivoting. Further, the control device  200  may change between operating modes and/or change an operating characteristics based on the time of day and/or the day of the week. For example, the control device  200  may be configured to operate in the first touch actuation mode during the day, and in the second touch actuation mode during the night 
     Further, the control device  200  may change operating characteristics and/or operating mode based on a learning algorithm. As another example, the control device  200  may be configured to learn that when the control device  200  receives an input (e.g., a tactile actuation) to turn a lighting load on at certain times of day, the user subsequently reduces the intensity level to a particular level (e.g., down from the turn-on intensity level to 25% intensity), and as a result, the control device  200  may be configured to initially turn the lighting load on to 25% intensity when the control device  200  receives an input to turn on the lighting load at that time of day. 
     As another example, the control device  200  may be configured to adjust the length of a blanking period based on a learning algorithm (e.g., the blanking period that occurs after (e.g., in response to) a touch actuation and/or the blanking period that occurs after (e.g., in response to) a tactile actuation). For instance, the control device  200  may determine that the blanking period is too short, and in response, lengthen the blanking period to avoid unintentional operations that are caused by accidental touch actuations received via the touch sensitive surface. One way that the control device  200  may determine that the blanking period is too short is by recognizing a series of events that indicate that an accidental touch actuation was received via the touch sensitive surface. For example, after turning the lighting load on in response to a first actuation (e.g., a touch actuation) of the actuation member  210  (e.g., the touch sensitive surface), the control device may receive (e.g., consistently receive) a second actuation (e.g., a touch actuation) that undoes or adjusts the control initiated by the first actuation (e.g., adjusts the intensity level). The control device may determine that the user had intended to apply a tactile actuation to the actuation member  210  and lengthen the blanking period after receiving touch actuations (e.g., the blanking period that occurs after (e.g., in response to) a touch actuation). In addition, after turning the lighting load off in response to a tactile actuation of the actuation member  210 , the control device then determine that it receives two subsequent inputs via the touch sensitive surface (e.g., touch actuations)—a first input that controls the lighting load in some manner (e.g., turns the lighting load on) and a second input that undoes the control initiated by the first input (e.g., turns the lighting load off). Accordingly, the control device  200  may determine that such a series of events occurs often, and in response, lengthen the blanking period after receiving tactile actuations (e.g., the blanking period that occurs after (e.g., in response to) a tactile actuation). 
       FIG.  4    is a top cross-sectional view of the control device  200  taken through the line shown in  FIG.  3   .  FIG.  5    is a right side cross-sectional view of the control device  200  taken through the center of the control device (e.g., through the line shown in  FIG.  3   ). As noted herein, the rear enclosure  230  may house the load control circuitry of the control device  200 . Although illustrated with the rear enclosure  230 , in some examples, such as when the control device  200  is a wireless, remote control device, the enclosure  230  may be omitted. In such examples, the control device  200  may connect to a base that is affixed to the toggle or paddle actuator of a standard light switch. 
     When the control device  200  is a wall-mounted dimmer switch, the control device  200  may comprise a yoke  232  that may be connected to the enclosure  230  and may be configured to mount the control device  200  to an electrical wallbox. As shown in  FIG.  4   , the control device  200  may comprise a diffuser  234  including a protruding portion  235  that extends through an elongated opening in the actuation member  210  to form the light bar  220 . The control device  200  may also comprise a light pipe  236  that may be configured to conduct light from one or more light sources  238  located inside of the enclosure  230  to the light bar  220 . For example, the light sources  238  may comprise one or more light-emitting diodes (LEDs) mounted to a main printed circuit board (PCB)  260  housed in the enclosure  230 . 
     The control device  200  may include the main PCB  260  that includes the load control circuitry used to control power delivered to an electrical load. For example, the main PCB  260  may include any combination of a control circuit (e.g., a primary control circuit), memory, a drive circuit, one or more controllably conductive devices, a zero-crossing detector, a low-voltage power supply, etc. (e.g., as shown in  FIG.  6   ). The control circuit of the main PCB  260  may be operatively coupled to a control input of the controllably conductive device, for example, via the drive circuit. The control circuit may be used for rendering the controllably conductive device conductive or non-conductive, for example, to control the amount of power delivered to the electrical load. The control device  200  (e.g., the main PCB  260 ) may also include mechanical switches, such as first and second tactile switches  262 ,  264 , that are configured to be actuated in response to actuations (e.g., tactile actuations) of the upper portion  216  and the lower portion  218  of the actuation member  210 , respectively (e.g., to control turning the load on and off). In some examples, the control device  200  may be configured to control a lighting load of the lighting control system  100  to turn the load on in response to an actuation of the first tactile switch  262  and to turn the load off in response to an actuation of the second tactile switch  264  (or vice versa). 
     When a user input (e.g., a touch actuation) is applied to an area of the front surface  214  located away from the first and second tactile switches  262 ,  264  (e.g., the area  215  over the pivot axis  222 ), the first and second tactile switches  262 ,  264  may not be actuated and the control device  200  may be configured to enter an advanced programming mode (e.g., as described herein) or to change operating modes (e.g., switch from an intensity control mode to a color control mode) in response to the touch actuation. For example, the area  215  may be located on the front surface  214  furthest away from the first and second tactile switch  262 ,  264 . It should be noted that although the touch actuation is described as being applied to the area  215  over the pivot axis  222 , such touch actuation may also be applied in other positions of the front surface  214  so long as those positions are sufficiently spaced away (e.g., furthest away) from the tactile switches to prevent accidental triggering of an unintended control function. For example, the touch actuation (e.g., a press-and-hold actuation) may be applied to an area of the front surface  214  that is located approximately half-way between (e.g., equidistant from) the first and second tactile switches  262 ,  264  to prevent accidental actuation of the tactile switches. 
     The control device  200  may also comprise a capacitive touch printed circuit board (PCB)  240 .  FIG.  6    is a rear view of the actuation member  210  showing a rear side  242  of the capacitive touch PCB  240 .  FIG.  7    is a front view of a front side  241  of the capacitive touch PCB  240  (i.e., the opposing view of the PCB  240  shown in  FIG.  6   ). The capacitive touch PCB  240  may be located behind (e.g., along the rear surface of) the actuation member  210  for detecting actuations of the front surface  214  of the actuation member  210 . The capacitive touch PCB  240  may be planar. The capacitive touch pads  244  of the capacitive touch PCB  240  may be located adjacent to (e.g., but not immediately behind) the light bar  220  for detecting touch actuations of the light bar  220  (e.g., and/or touch actuations of the front surface  214  of the actuation member  210  adjacent to the light bar  220 ) as shown by an area  249  (e.g., the touch sensitive surface) indicated by the dashed line in  FIG.  3   . In some examples, the capacitive touch PCB  240  is not located immediately behind the light bar  220  since the light pipe  236  may extend from the light sources  238  in the enclosure  230  to the light bar  220 . Further, the capacitive touch PCB  240  may be mounted or affixed to the actuation member  210 , for example, such that movement or the actuation member  210  causes movement of the capacitive touch PCB  240 . That is, the capacitive touch PCB  240  creates the touch sensitive surface on the front side of actuation member  210 , and as such, the touch surface also moves with tactile actuations of the actuation member  210 . 
     The capacitive touch PCB  240  may include a capacitive touch controller  252  and one or more receiving capacitive touch pads  244  for detecting the touch actuations on or adjacent to the light bar  220 . The receiving capacitive touch pads  244  may be arranged in a linear array that extends from the top to the bottom of the capacitive touch PCB  240  (e.g., below the area  249 ). The capacitive touch controller  252  may be configured to detect the position of the touch actuation along the length of the light bar  220  in response to touch actuations received from the one or more receiving capacitive touch pads  244  and to control the electrical loads according to the determined position. For example, the capacitive touch controller  252  may provide an output signal (e.g., an output signal V OUT ) to the main PCB  260 , and the main PCB  260  may control the electrical load(s) based on the determined position (e.g., by controlling a drive circuit of the control device  200 , by sending a message, such as a digital message, to the electrical load (s) and/or to a system controller, etc.). The capacitive touch pads  244  may include one or more electrodes. For example, as shown in  FIGS.  4  and  5   , the diffuser  234  may be located between actuation member  210  and the capacitive touch pads  244  on the capacitive touch PCB  240 , such there may not be any air between the actuation member  210  and the capacitive touch pads  244  to improve the sensitivity of the capacitive touch controller  252 . The capacitive touch PCB  240  may comprise a proximity capacitive touch pad  245  for detecting when a touch actuation of the front surface  214  of the actuation member  210  is at a distance from the light bar  220  (e.g., on the opposite side of the linear array of receiving capacitive touch pads  244  as the light bar  220 ). The proximity capacitive touch pad  245  may include one or more electrodes. The capacitive touch controller  252  may not be responsive to touch actuations of the front surface  214  of the actuation member  210  too far from the light bar  220  (e.g., when the capacitive touch controller  252  detects that the touch actuation is at a distance from the light bar  220  in response to the proximity capacitive touch pad  245 ). In some examples, the proximity capacitive touch pad  245  may be omitted. The capacitive touch PCB  240  may include a connector  254  that is configured to receive power from a power supply of the main PCB  260  to power the components of the capacitive touch PCB  240 . 
     The actuation member  210  may include pivot arms  250  that enable the actuation member  210  to pivot about the pivot axis  222  in response to a tactile actuation of the upper portion  216  and the lower portion  218 . As described herein, the capacitive touch PCB  240  may be mounted to the actuation member  210 . Accordingly, the capacitive touch PCB  240  may move (e.g. pivot) when the actuation member  210  pivots in response to a tactile actuation of the upper or lower portion  216 ,  218 . The pivot arms  250  may define the pivot axis  222  of the actuation member  210 . The PCB  240  may create the touch sensitive surface on the front surface  214  of the actuation member  210 , and as such, the touch sensitive surface may also move with tactile actuations of the actuation member  210 . In some examples, the capacitive touch PCB  240  may be a flexible PCB to enable further movement or bend of the capacitive touch PCB  240  in response to tactile actuations of the actuation member  210 . 
     The tactile actuation of the actuation member  210  may cause one of the first and second tactile switches  262 ,  264  of the main PCB  260  to be actuated (e.g., as shown in  FIG.  5 B ). For example, when the upper portion  216  of the actuation member  210  is actuated, the diffuser  234  may be moved toward the main PCB  260 . The diffuser  234  may comprise a first post  255  that may contact a first rubber membrane  256 , which may deflect inward and contact a first spacer rod  266 . As shown in  FIG.  4   , the first spacer rod  266  may be connected to the enclosure  230  via a first arm  267 . The deflection of first rubber membrane  256  may cause the first spacer rod  266  to move toward and actuate the first tactile switch  262  of the main PCB  260 . Similarly, when the lower portion  218  of the actuation member  210  is actuated, the diffuser  234  may be moved toward the main PCB  260 . The diffuser  234  may comprise a second post  257  that may contact a second rubber membrane  258 , which may deflect inward and contact a second spacer rod  268 . The second spacer rod  268  may be connected to the enclosure  230  via a second arm (not shown), which may be similar to the first arm  267 . The deflection of second rubber membrane  258  may cause the second spacer rod  268  to move toward and actuate the second tactile switch  264  of the main PCB  260 . Accordingly, the capacitive touch PCB  240 , which has capacitive touch pads  244  that creates a touch sensitive surface on the actuation member  210 , may be affixed to the actuation member  210 , and the actuation member  210 , when actuated, may pivot to actuate a tactile switch on a separate main PCB  260  of the control device  200 . As such, tactile actuations of the actuation member  210  may cause movement of the capacitive touch PCB  240  (e.g., and the diffuser  234 ). 
     Further, it should also be appreciated that the diffuser  234  may be configured to perform multiple functions. For example, the diffuser  234  may be configured to diffuse light emitted from light sources  238  located inside the enclosure  230  to the light bar  220  located on the front surface  214  of the actuation member  210 , and may also be configured to cause the actuation of one or more tactile switches  262 ,  264  located on the main PCB  260 . 
     In alternate examples, the capacitive touch PCB  240  may include tactile switches on the back of the capacitive touch PCB  240 . In such embodiments, the spacer rods  266 ,  268  would be stationary, and the tactile switches of the capacitive touch PCB  240  would be actuated by the stationary spacer rods  266 ,  268  in response to tactile actuations of the upper portion  216  and the lower portion  218  of the actuation member  210 . That is, tactile actuations of the actuation member  210  would cause the capacitive touch PCB  240 , and in turn the tactile switches of the capacitive touch PCB  240 , to move into and be actuated by the stationary spacer rods  266 ,  268 . 
     Although described as a capacitive touch PCB  240 , in some examples, the control device  200  may include any PCB, such as the main PCB  260 , at the position where the capacitive touch PCB  240  is illustrated in  FIG.  4 - 7   . In such examples, the PCB may be located behind (along the rear surface of) the actuation member  210 . This PCB may include any combination of circuitry, such as any combination of the circuitry described with reference to the capacitive touch PCB  240 , the main PCB  260 , a communication circuit (e.g., a wireless communication circuit), and/or a sensing circuit (e.g., a proximity sensing circuit, an ambient light sensing circuit, etc.). As such, the PCB may both move in response to actuations of the actuation member  210  and perform the functions enabled by the relevant circuitry (e.g., control internal or external light sources based on feedback from an ambient light sensor and/or a proximity sensor, wirelessly transmit control signals to external electrical loads, etc.). 
     In examples, a user input (e.g., a touch actuation) applied to the front surface  214  of the actuation member  210  may not cause the first tactile switch  262  or the second tactile switch  264  of the main PCB  260  to be actuated. For instance, when a touch actuation is applied to the area  215  of the front surface  214  located away (e.g., furthest away) from the first and second tactile switches  262 ,  264  (e.g., an area over the central pivot axis  222  or an area located approximately half-way between the first and second tactile switches), the user input may not cause the actuation member  210  to move (e.g., pivot). As a result, the spacer rods  266 ,  268  may not move toward and actuate the tactile switches  262 ,  264  of the main PCB  260 . As described herein, such a touch actuation may be treated by the control device  200  as an indication to enter an advanced programming mode, to change an operating mode of the control device  200 , and/or to perform a specific operation. 
     The capacitive touch PCB  240  may comprise a substrate  243 , the receiving capacitive touch pads  244 , and/or one or more ground planes. For example, as shown in  FIG.  6   , the rear side  242  of the capacitive touch PCB  240  may include a ground plane  270  (e.g., which may be located on the opposite side of the capacitive touch PCB  240  as the receiving capacitive touch pads  244 ). That is, the capacitive touch PCB  240  (e.g., the substrate  243  of the capacitive touch PCB  240 ) may reside between the capacitive touch pads  244  and the ground plane  270 . As such, the receiving capacitive touch pads  244  may be separated from the ground plane  270  by the capacitive touch PCB  240 . In addition, as shown in  FIG.  7   , the front side  241  of the capacitive touch PCB  240  may comprise a ground plane  272 , which may be electrically coupled to the ground plane  270  on the rear side  242  of the capacitive touch PCB  240 . Since the capacitive touch PCB  240  may be mounted to a rear side of the actuation member  210 , and since the actuation member  210  is configured to pivot in response to tactile actuations of the upper portion  216  and the lower portion  218 , the distance between the receiving capacitive touch pads  244  and the yoke  232  may change when the actuation member  210  is actuated. Without the inclusion of the ground plane, the change in distance between the receiving capacitive touch pads  244  and the yoke  232  could cause the receiving capacitive touch pads  244  to provide noisy feedback, which in turn could cause mis-operation of the control device  200 . The ground plane may shield the receiving capacitive touch pads  244  from any noise that may be created by the yoke  232  when the receiving capacitive touch pads  244  are moving in response to a tactile actuation of the actuation member  210 . For example, the ground plane may shield the non-functional portions (e.g., back side) of the receiving capacitive touch pads  244  from noise. Finally, in some examples, one or more of the ground planes may be internal to the capacitive touch PCB  240  (i.e., located between two or more layers of the substrate  243  of the capacitive touch PCB  240 ). 
     Further, in some scenarios, the yoke  232  may be grounded. In such instances, the ground plane  270  on the rear side  242  of the capacitive touch PCB  240  and/or the ground plane  272  on the front side  241  of the capacitive touch PCB  240  may prevent the yoke  232  (e.g., the grounded yoke) from generating a touch actuation as the capacitive touch pads  244  move closer to and further away from the yoke  232 . Additionally or alternatively, a metal faceplate may be installed over the control device  200  and may be in contact with (e.g., connected to) the yoke  232 . In such instances, the ground plane  270  on the rear side  242  of the capacitive touch PCB  240  and/or the ground plane  272  on the front side  241  of the capacitive touch PCB  240  may prevent the yoke  232  when not grounded from generating a touch actuation via the capacitive touch pads  244  when a metal faceplate is contacted. 
     The load control device  200  may include an insulator  259 . The insulator  259  may prevent optical reflections off the yoke from the light bar  220 . 
     The capacitive touch PCB  240  may comprise five receiving capacitive touch pads  244  (e.g., capacitive touch regions A-E) as shown in  FIG.  7   . The receiving capacitive touch pads  244  may each be triangular in shape and may be arranged in a linear array that extends from the top to the bottom of the capacitive touch PCB  240  (e.g., on the right side of the capacitive touch PCB  240 ). For example, regions A and E of the receiving capacitive touch pads  244  may be electrically coupled together. The proximity capacitive touch pad  245  may extend from the top to the bottom of the capacitive touch PCB  240  and located farther away from the light bar  220  (which may be to the right of touch pads  244 ) than the linear array of receiving capacitive touch pads  244  (e.g., to the left of the receiving capacitive touch pads  244 ). The linear array of the receiving capacitive touch pads  244  and the proximity capacitive touch pad  245  may extend along a longitudinal axis of the control device  200  and may be oriented parallel to each other. 
     The receiving capacitive touch pads  244  and the proximity capacitive touch pad  245  may be configured according to a mutual capacitance sensing technique. The receiving capacitive touch pads  244  may be surrounded by a first transmission trace  246  and the proximity capacitive touch pad  245  may be surrounded by a second transmission trace  248 . The control device  200  may be configured to and the proximity capacitive touch pad  245 , respectively, which may reduce the influence of other objects in the environment of the control device  200  from affecting the capacitive touch sensing. The first and second transmission traces  246 ,  248  may be electrically coupled together. 
     The actuation member  210  and the diffuser  234  may be located between the touch sensitive surface (e.g., the front surface  214  of the actuation member  210 ) and the receiving capacitive touch pads  244  on the capacitive touch PCB  240 . As shown in  FIG.  5   , the distance between the touch sensitive surface (e.g., the front surface  214  of the actuation member  210 ) and the receiving capacitive touch pads  244  on the capacitive touch PCB  240  may not be uniform over the length of the actuation member  210  (e.g., the combined assembly formed by the actuation member  210  and the diffuser  234  may not have a uniform thickness). For instance, the thickness of the actuation member  210  and the diffuser  234  may be thinnest in the middle (e.g., near the pivot axis  222 ) and may get gradually thicker towards the top and bottom of the actuation member  210 . In examples where the distance between the touch sensitive surface and the receiving capacitive touch pads  244  on the capacitive touch PCB  240  is not uniform, the capacitive touch controller  252  may apply different sensitives to the receiving capacitive touch pads  244  based on, for example, the distance between the touch sensitive surface and each respective receiving capacitive touch pad  244 . For example, the capacitive touch controller  252  on the capacitive touch PCB  240  may use different voltage thresholds V TH  for one or more of the capacitive touch pads  244 , for example, to ensure that the capacitive touch PCB  240  reacts in a similar or identical manner to comparable touches at different positions along the length of touch sensitive surface of the actuation member  210 . As described in more detail below, the capacitive touch controller  252  on the capacitive touch PCB  240  may set the respective voltage thresholds V TH  of the capacitive touch pads  244 . 
     For example, as described in more detail below, the capacitive touch controller  252  may compare a measured voltage to a voltage threshold V TH  and generate an output signal V OUT  that may indicate when the measured voltage exceeds the voltage threshold V TH . The capacitive touch controller  252  may use smaller voltage thresholds V TH  for the capacitive touch pads  244  that are separated from the touch sensitive surface by thicker portions of the actuation member  210  and the diffuser  234  as compared to the voltage thresholds V TH  that are used for the capacitive touch pads  244  that are separated from the touch sensitive surface by thinner portions of the actuation member  210  and the diffuser  234 . Accordingly, the capacitive touch controller  252  may offset the impact of the varying thickness of the actuation member  210  and the diffuser  234  by applying different sensitivities (e.g., using varying voltage thresholds V TH ) for the capacitive touch pads  244  that are separated from the touch sensitive surface by varying thicknesses of the actuation member  210  and the diffuser  234 . For example, the capacitive touch controller  252  may use a first voltage threshold V TH  for the capacitive touch pads  244  labeled “A” and “E”, a second voltage threshold V TH  for the capacitive touch pads  244  labeled “B” and “D”, and a third voltage threshold V TH  for the capacitive touch pad  244  labeled “C”. In such an example, the first voltage threshold V TH  may be less than the second voltage threshold V TH , and the second voltage threshold V TH  may be less than the third voltage threshold V TH . 
     Electrical noise may affect the accuracy of the touch sensitive surface of the control device  200 . To avoid inaccurate readings, the control device  200  may be configured to sample (e.g., respond to) the output signal V OUT  from the capacitive touch controller  252  during certain times but not others. For example, the control device  200  may be configured to stop sampling (e.g., not respond to) the output signal V OUT  from the capacitive touch controller  252  during situations and circumstances that are more likely to be impacted by electrical noise (e.g., noisy events), such as, for example, when the controllably conductive device of the control device  200  is rendered conductive and/or when transmitting and/or receiving wired or wireless communications via the communication circuit of the control device  200 . For example, the control device  200  may sample the output signal V OUT  from the capacitive touch controller  252  during a time window before or after a zero-crossing of the AC mains line voltage to, for example, avoid sampling the output signal V OUT  during times when the controllably conductive device of the control device  200  is rendered conductive. Further, the control device  200  may also, or alternatively, be configured to sample the output signal V OUT  based on the actual times when the controllably conductive device is rendered. For example, the control device  200  may be configured to sample the output signal V OUT  during a time window right before or after the events when the controllably conductive device of the control device  200  is rendered conductive. Similarly, in some instances, the control device  200  may detect an event that is characterized by an increase in electrical noise within the control device  200  (e.g., a noisy event), and in response, may not sample the output signal V OUT  for a time period based on the noisy event (e.g., where the time period may encompass the noisy event). Accordingly, the control device  200  may ignore less accurate (e.g., inaccurate) outputs from the capacitive touch controller  252  that occur due to noisy events. 
       FIG.  8    is a perspective view of another example control device  280  that may be a dual dimmer switch. The control device  280  may comprise a user interface  282  including an actuation member  284  having first and second light bars  286 ′,  286 ″ on opposing sides of the actuation member  284 . The actuation member  284  may have a touch sensitive surface defined by two distinct touch sensitive areas, such as a first area adjacent to and/or overlapping the first light bar  286 ′ and a second area adjacent to and/or overlapping the second light bar  286 ″ (e.g., the second area may be located on the opposite side of a front surface  288  of the actuation member  284  as the first area). 
       FIG.  9    is a front view of a front side  291  of a capacitive touch PCB  290  of the control device  280 . The capacitive touch PCB  290  may be located behind (e.g., along a rear surface of) the actuation member  284  for detecting actuations of the front surface  288  of the actuation member  284 . The capacitive touch PCB  290  may comprise a substrate  292  and a first array of receiving capacitive touch pads  294 ′ that may be located adjacent to (e.g., but not immediately behind) the first light bar  286 ′ for detecting touch actuations of the first light bar  286 ′ (e.g., and/or touch actuations of in the first area on the front surface  288  of the actuation member  284  adjacent to the first light bar  286 ′). The capacitive touch PCB  290  may also comprise a second array of receiving capacitive touch pads  294 ″ that may be located adjacent to (e.g., but not immediately behind) the second light bar  286 ″ for detecting touch actuations of the second light bar  286 ″ (e.g., and/or touch actuations of in the second area on the front surface  288  of the actuation member  284  adjacent to the second light bar  286 ″). The first and second arrays of receiving capacitive touch pads  294 ′,  294 ″ may be surrounded by respective transmission traces  296 ′,  296 ″, which may be energized to charge the respective receiving capacitive touch pads. 
     In addition, the capacitive touch PCB  290  may comprise first and second proximity capacitive touch pads  295 ′,  295 ″ adjacent to the first and second arrays of receiving capacitive touch pads  294 ′,  294 ″, respectively. The first and second proximity capacitive touch pads  295 ′,  295 ″ may be surrounded by respective transmission traces  298 ′,  298 ″, which may be energized to charge the respective receiving capacitive touch pads. The substrate  292  may comprise openings  299  through which posts (e.g., posts  255 ) may extend to actuate mechanical switches (e.g., tactile switches  262 ,  264 ) when the actuation member  284  is actuated with a tactile actuation (e.g., as described above for the actuation member  210 ). The proximity capacitive touch pads  295 ′,  295 ″ may be used to detect when an touch actuation of the front surface  288  of the actuation member  210  is between the first and second areas on the touch sensitive surface, for example, to ensure accurate control based on the inputs received via the first or second area (e.g., on the first or second light bars  286 ′,  286 ″, respectively). In other examples, the control device  280  may include a single proximity capacitive touch pad that is located between the first and second arrays of receiving capacitive touch pads  294 ′,  294 ″. 
     The control device  280  may control two different loads in response to touch actuations on the two respective areas of the touch sensitive surface (e.g., the front surface  288 ). For example, the control device  280  may be configured to control a lighting load based on touch actuations received via the first area of the touch sensitive surface and a motor load (e.g., an exhaust fan and/or a ceiling fan) based on touch actuations received via the second area of the touch sensitive surface. As another example, the control device  280  may be configured to control two different characteristics of the same load based on touch actuations received via the first and second areas of the touch sensitive surface. For instance, the control device  280  may be configured to control the intensity level of a lighting load based on touch actuations received via the first area of the touch sensitive surface and control the color (e.g., color temperature and/or full color control) of the lighting load based on touch actuations received via the second area of the touch sensitive surface. The control device  280  may operate similar to and include similar functionality as the control device  200 , but with the inclusion of the user interface  282  and the capacitive touch PCB  290 . Further, in some examples, the control device  200  may include the user interface  282  and the capacitive touch PCB  290 , and be configured to control two different loads in response to touch actuations on the two respective areas of the touch sensitive surface. 
       FIGS.  10 - 15    depict another example of a remote control device  1200  that may be installed in a load control system, such as a lighting control system. For example, the remote control device  1200  may be installed in the lighting control system  100  of  FIG.  1   . The load control system may include a mechanical switch  1290  that may be in place prior to installation of the remote control device  1200 , for example pre-existing in the load control system. As shown, the mechanical switch  1290  may be a standard decorator paddle switch. The load control system may further include one or more electrical loads, such as lighting loads. The mechanical switch  1290  may be coupled in series electrical connection between an alternating current (AC) power source and the one or more electrical loads. 
     The mechanical switch  1290  may include a paddle actuator  1292  that may be actuated to turn on and/or turn off, the one or more electrical loads. The mechanical switch  1290  may include a bezel  1293  that surrounds the paddle actuator  1292 . An upper portion of the paddle actuator  1292  may protrude from the bezel  1293  (e.g., in a first orientation) when the electrical load is off, and a lower portion of the paddle actuator  1292  may protrude from the bezel  1293  (e.g., in a second orientation, as shown in  FIG.  4   ) when the electrical load is on, or vice versa. The mechanical switch  1290  may include a yoke (not shown) that enables mounting of the mechanical switch  1290  to a structure. For example, the yoke may be fastened to a single-gang wallbox that is installed in an opening of a structure (e.g., such as a wall, ceiling, etc.). As shown, a faceplate  1296  may be secured to the mechanical switch  1290 , for instance to the yoke. The faceplate  1296  may define a front surface  1261  and an opposed rear surface  1263 . The front surface  1261  may alternatively be referred to as an outer surface of the faceplate  1296 , and the rear surface  1263  may alternatively be referred to as an inner surface of the faceplate  1296 . The faceplate  1296  may be made of any suitable material, such as plastic. The remote control device  1200  may be configured to be installed over the paddle actuator  1292  of the mechanical switch  1290  (e.g., mounted to the paddle actuator  1292 , the bezel  1293 , and/or the faceplate  1296 ). 
     The remote control device  1200  may include a base  1220  and a control unit  1230  (e.g., a control module). The control unit  1230  may be mounted to the base  1220 . For example, the base  1220  may be configured to attach the remote control device  1200  to the mechanical switch  1290 . The remote control device  1200  may also include a spacer  1210 , which may be a shim and may be configured to compensate for mechanical switches having paddle actuators  1292  that protrude at greater lengths from the bezel  1293 . The control unit  1230  may be mounted to the base  1220  with or without the spacer  1210 . When the spacer  1210  is used, the spacer  1210  may be attached to the base  1220  and the control unit  1230  may be attached to the spacer  1210 . 
     The base  1220  may alternatively be referred to as a base portion, a mounting frame, or a mounting assembly. The control unit  1230  and the base  1220  may be configured such that the control unit  1230  may be removably attached to the base  1220 . The base  1220  may be mounted over (e.g., attached to) the paddle actuator  1292  of the mechanical switch  1290  without removing the faceplate  1296 . In this regard, the remote control device  1200  may be mounted over an installed mechanical switch, such as the mechanical switch  1290 , without the need to remove the faceplate  1296  and/or perform any electrical re-wiring of the mechanical switch  1290 . For example, the base  1220  may be attached to the bezel  1293  of the mechanical switch  1290  using an adhesive  1205 . The adhesive  1205  may be configured to secure the base  1220  to the bezel  1293 . 
     As shown, the base  1220  may define a frame  1221 . The frame  1221  may define primary attachment tabs  1222 . The primary attachment tabs  1222  may be configured to releasably secure the control unit  1230  to the base  1220 . The primary attachment tabs  1222  may be configured to engage the control unit  1230  (e.g., a complementary structure of the control unit  1230 ). The frame  1221  may further define apertures  1224 . The apertures  1224  may be configured to engage the spacer  1210  (e.g., a complementary structure of the spacer  1210 ). 
     The spacer  1210  may define auxiliary attachment tabs  1212 . The auxiliary attachment tabs  1212  may be configured to engage the control unit  1230  (e.g., complementary structure of the control unit  1230 ). The spacer  1210  may define primary snaps  1214 . The primary snaps  1214  may be configured to engage the primary attachment tabs  1222  of the base  1220 . For example, the primary snaps  1214  may releasably secure with the primary attachment tabs  1222  of the base  1220  such that the spacer  1210  is releasably attached to the base  1220 . The spacer  1210  may define clips  1216 . The clips  1216  may be configured to engage the base  1220  when the spacer  1210  is attached to the base  1220 . For example, the clips  1216  may be configured to secure the spacer  1210  to the base  1220 . The spacer  1210  may define pins  1218 . The pins  1218  may be configured to align and/or maintain alignment between the spacer  1210  and the base  1220 . The pins  1218  may extend from a perimeter of the spacer  1210 . The pins  1218  may be configured to be received by the base  1220  (e.g., complementary structure of the base  1220 ). For example, the pins  1218  may be received by the apertures  1224  when the spacer  1210  is attached to the base  1220 . 
     The control unit  1230  may include a user interface comprising an actuation member  1232 , a housing  1234 , and a battery holder  1270 . For example, the actuation member  1232  may be attached to the housing  1234 . The housing  1234  may define an upper wall  1241 , a lower wall  1242 , and opposed side walls  1243 . The upper wall  1241 , the lower wall  1242 , and the side walls  1243  of the housing  1234  may extend from respective edges of the actuation member  1232  (e.g., from a perimeter defined by the actuation member  1232 ). The housing  1234  may define primary snaps  1252  and/or auxiliary snaps  1254 . For example, the upper wall  1241  and the lower wall  1242  may define primary snaps  1252  and/or auxiliary snaps  1254 . The control unit  1230  may be attached to the base  1220  using the primary snaps  1252  and/or to the spacer  1210  using the auxiliary snaps  1254 . The primary snaps  1252  may be configured to engage the primary attachment tabs  1222  of the base  1220 . For example, the primary snaps  1252  may engage the primary attachment tabs  1222  of the base  1220  when the spacer  1210  is not used. The auxiliary snaps  1254  may be configured to engage the auxiliary attachment tabs  1212  of the spacer  1210 . For example, the auxiliary snaps  1254  may engage the auxiliary attachment tabs  1212  of the spacer  1210  when the spacer  1210  is used. 
     The housing  1234  of the control unit  230  may include a pivot bar  1250 . The pivot bar  1250  may extend between the opposed side walls  1243  of the housing  1234 . The pivot bar  1250  may be configured to receive the battery holder  1270 . For example, the battery holder  1270  may pivotally mount to the pivot bar  1250 . The battery holder  1270  may pivot about the pivot bar  1250  between a first position and a second position. The first position may correspond to the battery holder being proximate to the lower wall  1242  of the housing  1234 , while the second position may correspond to the battery holder  1270  being proximate to the upper wall  1241  of the housing  1234 . 
     The control unit  1230  may include a printed circuit board (PCB)  1244  (e.g., a flexible or rigid printed circuit board). The PCB  1244  may include a processor or controller and a touch sensitive device (e.g., which itself may include a separate processor). As such, in some examples, the PCB  1244  may act as both a main PCB and a capacitive touch PCB (e.g., may operate similarly as the main PCB  240  and the capacitive touch PCB  260  of the control device  200 ). The control unit  1230  may also include a light bar  1239  configured to be illuminated by one or more light sources  1237  (e.g., one or more LEDs). The light bar  1239  may be illuminated via a light guide film  1246  on the printed circuit board  1244 . For example, the light sources  1237  on the printed circuit board  1244  may illuminate the light bar  1239  through the light guide film  1246 . The light bar  1239  may be illuminated to visibly display information to a user of the control unit  1230 . The front surface  1235  of the actuation member  1232  may be actuated along the light bar  1239  to adjust the amount of power delivered to the lighting load according to the position of the actuation. 
     As shown in  FIGS.  10 - 15   , the control unit  1230  may be rectangular in shape and elongate between the upper wall  1241  and the lower wall  1242 . It should be appreciated that the control unit  1230  is not limited to the illustrated rectangular geometry, and that control unit may alternatively be configured with other suitable geometries. In accordance with the illustrated orientation of the control unit  1230 , the upper wall  1241  may be referred to as an upper end of the control unit  1230  and the lower wall  1242  may be referred to as a lower end of the control unit  1230 . The upper and lower walls  1241 ,  1242  of the control unit  1230  may also be referred to as first and second ends of the housing  1234 , respectively. The control unit  1230  (e.g., the housing  1234 ) may define a void  1248  ( FIG.  15   ). The void  1248  may be configured to receive the printed circuit board  1244  in an attached position. The void  1248  may be defined by the upper wall  1241 , the lower wall  1242 , and the opposing side walls  1243 . The void  248  may include an upper portion that is defined between the pivot bar  1250  and the upper wall  1241 , and a lower portion that is defined between the pivot bar  1250  and the lower wall  1242 . The housing  1234  may be made of any suitable material, such as plastic or metal. 
     The control unit  1230  may operate in a similar manner as the control device  200 . For example, the actuation member  1232  may include a front surface  1235  having an upper portion  1236  and a lower portion  1238 , and the control unit  1230  may be configured to control an electrical load in response to actuation of the upper or lower portions  1236 ,  1238  of the actuation member  1232 . The actuation member  1232  may also receive user inputs that do not cause the actuation member  1232  to pivot. For example, the control unit  1230  may be configured to control an electrical load in response to touch actuations along the front surface  1235  of the actuation member  1232 . 
     The control unit  1230  (e.g., the PCB  1244 ) may include mechanical switches, such as first and second tactile switches  1245   a ,  1245   b , that are configured to be actuated in response to actuations (e.g., tactile actuations) of the upper portion  1236  and the lower portion  1238  of the actuation member  1232 , respectively (e.g., to control turning the load on and off). For example, the control unit  1230  may be configured to control a lighting load of the lighting control system  100  to turn the load on in response to an actuation of the first tactile switch  1245   a  and to turn the load off in response to an actuation of the second tactile switch  1245   b  (or vice versa). For example, the control device  1200  may be configured to turn the lighting load on to a previous intensity level (e.g., before the lighting load was previously turned off) or to a preset intensity level (e.g., a predetermined or locked preset intensity level) in response to a tactile actuation of the upper portion  1236  of the actuation member  1232 . The tactile actuation of the actuation member  1232  may cause one of the first and second tactile switches  1245   a ,  1245   b  of the PCB  1244  to be actuated. For example, the control unit  1230  (e.g., the housing  1234 ) may define a first nub  1259   a  and a second nub  1259   b . When the upper portion  1236  of the actuation member  1232  is actuated, the first tactile switch  1244   a  may be moved toward the first nub  1259   a . As such, the actuation of the upper portion  1236  the actuation member  1232  may cause the first tactile switch  12441  to move toward and contact the first nub  1259   a . Similarly, when the lower portion  1238  of the actuation member  1232  is actuated, the second tactile switch  1244   b  may be moved toward the second nub  1259   b . As such, the actuation of the lower portion  1238  the actuation member  1232  may cause the second tactile switch  1244   b  to move toward and contact the second nub  1259   b.    
     The actuation member  1232  may be configured to pivot in response to a tactile actuation of the upper portion  1236  and the lower portion  1238 . The actuation member  1232  may pivot about a lower axis in response to a tactile actuation of the upper portion  1236  of the actuation member and pivot about an upper axis in response to a tactile actuation of the lower portion  1238  of the actuation member  1232  (e.g., as opposed to pivoting about a midpoint of the actuation member). For example, the upper wall  1241  of the housing  1234  may include first and second recesses (not shown), and the lower wall  1242  of the housing  1234  may include first and second recesses  1253   a ,  1253   b , respectively. Further, the actuation portion  1232  may include first and second top notches  1231   a ,  1231   b , respectively, and first and second bottom notches  1233   a ,  1233   b , respectively. As such, when the upper portion  1236  of the actuation member  1232  is actuated, the first and second bottom notches  1233   a ,  1233   b  of the actuation member  1232  may pivot about the first and second recesses  1253   a ,  1253   b  of the lower wall  1242 , and the first tactile switch  1244   a  may be moved toward and contact the first nub  1259   a . Similarly, when the lower portion  1238  of the actuation member  1232  is actuated, the first and second top notches  1231   a ,  1231   b  of the actuation member  1232  may pivot about the first and second recesses (not shown) of the upper wall  1241 , and the second tactile switch  1244   b  may be moved toward and contact the second nub  1259   b.    
     The actuation member  1232  may also receive user inputs that do not cause the actuation member  1232  to pivot. The control unit  1230  may be configured to control an electrical load in response to touch actuations along the front surface  1235  of the actuation member  1232 . For example, at least a portion of the front surface  1235  of the actuation member  1232  may be configured as a touch sensitive surface (e.g., a capacitive touch surface) that is configured to receive (e.g., detect) inputs (e.g., touch actuations/inputs), such as point actuations or gestures, from a user of the control device  1200 . The touch sensitive surface of the actuation member  1232  may be located adjacent to and/or overlap with the light bar  1239 . For example, during a normal operating mode of the control device  1200 , the front surface  1232  of the actuation member  1232  may be actuated along the light bar  1239  (e.g., along the touch sensitive surface) to adjust the amount of power delivered to, and thus the intensity level of, the lighting load according to the position of the touch actuation, for example, between a low-end intensity level L LE  and a high-end intensity level Lam. Although described primarily in context of a capacitive touch surface, it should be appreciated that the control device  1200  is not so limited, and in some examples, at least a portion of the front surface  1235  of the actuation member  1232  may be configured as a different type of touch sensitive surface, such as a resistive touch surface, an inductive touch surface, a surface acoustic wave (SAW) touch surface, an infrared touch surface, acoustic pulse touch surface, or the like. 
     The control device  1200  may control the magnitude of a load current conducted through the lighting load based on a single discrete input along the touch sensitive surface and/or based on a plurality of consecutive inputs along the touch sensitive surface. For example, the user may tap their finger at a position along the touch sensitive surface, and in response, the control device  1200  may turn the lighting load on to an intensity level based on the position. As an example, if the lighting load is off, the control device  1200  may turn the lighting load on to an intensity level based on the position of a touch actuation along the touch sensitive surface of the actuation member  1232 . While the lighting load is on, the user may move (e.g., slide) their finger along the touch sensitive surface, and in response, the control device  1200  may adjust (e.g., continuously control) the magnitude of the load current conducted through the lighting load based on the positions of a plurality of inputs along the touch sensitive surface. 
     Further, in a color control mode, the control device  1200  may control a color of the lighting load based on the position of a touch actuation along the touch sensitive surface of the actuation member  1232  (e.g., by controlling a color temperature of the lighting load or by applying full color control over the lighting load). For example, the light bar  1239  may be configured to illuminate a spectrum of colors through the length of the light bar  1239  (e.g., across the full visible color spectrum, a subset of the visual color spectrum, and/or the light spectrum associated with the color temperatures of a black body radiator). Accordingly, the control device  1200  may control the color of the lighting load based on the position of a touch actuation along the touch sensitive surface, and in turn, the corresponding color of that position on the light bar  1239 . 
     The PCB  1244 , which may include capacitive touch pads that creates a touch sensitive surface on the actuation member  1232 , may be affixed to the actuation member  1232  and may be responsive to touch actuations. The front surface  1235  of the actuation member  1232  of the control unit  1230  may define a user interface that is configured to receive inputs, such as gestures, from a user of the remote control device  1200 . The user interface may be configured as a touch sensitive surface (e.g., a capacitive touch surface) that is configured to receive (e.g., detect) inputs, such as gestures, from a user of the control unit  1230 . For example, the printed circuit board  1244  may include one or more capacitive touch regions, or surfaces (e.g., similar to the receiving capacitive touch pads  244  and/or the proximity capacitive touch pad  245  mounted to the capacitive touch PCB  240  of the control device  200 ). The printed circuit board  1244  may include one or more linear capacitive touch regions that faces an inner surface of the actuation member  1232  when the printed circuit board  1244  is disposed in the void  1248 . The front surface  1235  of the actuation member  1232  may be configured to detect touches along an x-axis, a y-axis, or both an x-axis and a y-axis. Accordingly, the actuation member  1232 , when actuated, may pivot to actuate one of the first or second tactile switches  1244   a ,  1244   b , such that tactile actuations of the actuation member  1232  may cause movement of the PCB  1244 . 
     The control unit  1230  may further include a control circuit (e.g., a processor, not shown) and a wireless communication circuit (e.g., an RF transceiver, not shown). The control unit  1230  may be configured to translate one or more inputs (e.g., user inputs) from the user interface into respective control signals that may be used to control a load control device of a load control system. The one or more inputs may be applied via touches or presses of the upper portion  1236  and/or lower portion  1238  of the actuation member  1232 . For example, the control circuit may be configured to receive input signals (e.g., that correspond to the user inputs) in response to actuations of the upper portion  1236  and/or lower portion  1238  by a user of the remote control device  1200 . For example, the input signals received by the control circuit may be the respective control signals translated from the control interface inputs. The control circuit may be configured to generate commands that the user desires the control unit  1230  to execute in response to the input signals produced in response to actuations of the upper portion  1236  and/or lower portion  1238 . The control unit  1230  may be configured to cause the wireless communication circuit to transmit one or more control signals including the commands generated by the control circuit. 
     The control circuit may be configured to cause the wireless communication circuit to transmit respective commands that correspond to inputs and/or gestures received by the upper portion  1236  and/or lower portion  1238 . For example, the remote control device  1200  may be operable to transmit wireless signals, for example radio frequency (RF) signals, to a load control device, one or more electrical loads, and/or a central processor of a load control system. The remote control device  1200  may be associated with the load control device and the one or more electrical loads during a configuration procedure of the load control system. 
     The control circuit may be configured to cause the wireless communication circuit to transmit respective commands that correspond to interpreted gestures received at the touch sensitive surface. For example, the remote control device  1200  may be operable to transmit wireless signals, for example radio frequency (RF) signals, to a load control device, one or more electrical loads, and/or a central processor of a load control system. The remote control device  1200  may be associated with the load control device and the one or more electrical loads during a configuration procedure of the load control system. 
     The light bar  1239  of the control unit  1230  may be configured to provide a visual indication of a command issued by the remote control device  1200 . For example, the control circuit may be configured to, upon receiving a gesture indicative of a command to change an amount of power delivered to an electrical load, such as a command to dim a lighting load, indicate the amount of power delivered to the electrical load by temporarily illuminating a number of the LEDs that corresponds with the desired amount of power (e.g., the desired dimming level of the lighting load). In such an example, the control circuit may be configured to cause the LEDs to be illuminated simultaneously, to illuminate sequentially with some or little overlap before fading, or to otherwise illuminate as desired. The control unit  1230  may be configured to be attached to the base  1220  with the light bar  1239  located on a predetermined side of the control unit  1230  (e.g., the right side of the control unit as shown in  FIG.  10   ), for example, such that the light bar  1239  may be illuminated to indicate the amount of power presently being delivered to the electrical load. The printed circuit board  1244  may define a fold  1247  such that the light sources  1237  mounted thereto illuminate through the printed circuit board  1244  and light guide film  1246  to the light bar  1239 . 
     The control unit  1230  may be configured to prioritize user inputs that cause the actuation member  1232  to pivot over user inputs that do not cause the actuation member  1232  to pivot, or vice versa. For example, when the lighting load is off and a user moves a finger close to the upper portion  1236  of the actuation member  1232  causing the control unit  1230  to detect a touch actuation via the touch sensitive surface (e.g., along the light bar  1239 ), the control unit  1230  may temporarily delay responding to the touch actuations received via the touch sensitive surface to see if a user is attempting to actuation the upper portion  1236  of the actuation member  1232  to turn on the lighting load. Accordingly, the control unit  1230  may avoid turning on the lighting load to an intensity level based on the position of the actuation on the light bar  1239  (e.g., in response to the touch sensitive surface) if the user&#39;s finger happens to sweep past the light bar  1239  while actuating the upper portion  1236  of the actuation member  1232  or if the user&#39;s finger actuates the upper portion  1236  of the actuation member  1232  too close to the light bar  1239 . In addition, when the lighting load is on and a user moves a finger close to the lower portion  1238  of the actuation member  1232  causing the control unit  1230  to detect a touch actuation via the touch sensitive surface, the control unit  1230  may temporarily ignore the touch actuations received via the touch sensitive surface after the actuation of the lower portion  1238 . Accordingly, the control unit  1230  may avoid turning on the lighting load again if the user&#39;s finger happens to sweep past the light bar  1239  while moving away from the lower portion  1238  of the actuation member  1232 . 
     The control unit  1230  may, for example, be configured to prioritize inputs received in response to actuation of the actuation member  1232  over the inputs received via the touch sensitive surface by ignoring inputs received via the touch sensitive surface when a tactile actuation of the actuation member  1232  is received within a blanking period (e.g., 200 ms) after an initial detection of a touch actuation received via the touch sensitive surface. The blanking period may occur after (e.g., in response to) a touch actuation. That is, the control unit  1230  may ignore touch actuations received via the touch sensitive surface when a touch actuation of the actuation member  1232  is received within the blanking period (e.g., a touch actuation that begins during the blanking period). For instance, in some examples, the control unit  1230  may start the blanking period (e.g., a timer) in response to receiving a touch actuation via the touch sensitive surface, and ignore touch actuations received via the touch sensitive surface during the blanking period if the control unit  1230  receives a touch actuation of the actuation member  1232  during the blanking period (e.g., a touch actuation begins during the blanking period). As such, the control unit  1230  may prioritize user inputs that cause the actuation member  1232  to pivot over user inputs that do not cause the actuation member  1232  to pivot during the blanking period. 
     Further, even if a blanking period is implemented, the control unit  1230  may be configured to respond to a quick “tap” along the touch sensitive surface. For instance, the control unit  1230  may be configured to determine that a touch actuation is at a position on the touch sensitive surface for an amount of time that is shorter than the blanking period without the actuation member  1232  being actuated (e.g., a touch actuation starts and finishes before the end of the blanking period) and, in response, turn the lighting load on to an intensity level associated with the position in response to the touch actuation. Accordingly, the control unit  1230  may both implement the blanking period to avoid unintentional touch actuations along the touch sensitive surface and still respond quickly to intentional touch actuations along the touch sensitive surface. 
     The control unit  1230  may be configured to turn the lighting load on in response to a touch actuation received via the touch sensitive surface even when implementing the blanking period. For example, the control unit  1230  may be configured to receive a touch actuation via the touch sensitive surface at a position for an amount of time that is greater than the blanking period without the tactile switch being actuated (e.g., a touch actuation begins during the blanking period and ends after the blanking period) and, in response, turn the lighting load on to an intensity level associated with the position in response to the touch actuation. Further, the control unit  1230  may adjust the length of a blanking period, for example, through a user input received (e.g., a touch actuation and/or a tactile actuation) while in an advanced programming mode. For instance, in some examples, the blanking period may be configured to be greater than one second (e.g., multiple seconds). In such examples, the control unit  1230  may respond to a press-and-hold touch actuation along the light bar  1239  by turning the lighting load on to an intensity level associated with the position of the press-and-hold actuation. 
     The control unit  1230  may be configured to temporarily ignore inputs received via the touch sensitive surface after a tactile actuation of the actuation member  1232  that causes the lighting load to turn on or off. The control unit  1230  may be configured in this manner to, for example, avoid mistakenly turning the lighting load back on and/or adjusting the power delivered to (e.g., the intensity level of) the lighting load after a tactile actuation of the actuation member  1232 . For example, the control unit  1230  may be configured to ignore inputs received via the touch sensitive surface during a blanking period after detecting a tactile actuation of the actuation member to turn the lighting load on or off. For instance, in some example, the control unit  1230  may start the blanking period in response to turning on or off the lighting load and, during the blanking period, ignore inputs received via the touch sensitive surface during the blanking period. As such, through the use of a blanking period (e.g., a second blanking period), the control unit  1230  may be able avoid unintentional touch actuations along the touch sensitive surface after a tactile actuation of the actuation member  1232 . In sum, the control unit  1230  may be configured with one or more blanking periods, such as a first blanking period that is used to avoid unintentional touch actuations after an initial detection of a touch actuation received via the touch sensitive surface and prior to tactile actuations of the actuation member  1232  (e.g., a blanking period that occurs after (e.g., in response to) a touch actuation), and/or a second blanking period that is used to avoid unintentional touch actuations after tactile actuations of the actuation member  1232  (e.g., a blanking period that occurs after (e.g., in response to) a tactile actuation). 
     The control unit  1230  may be configured to detect that a touch actuation is received at a position of the touch sensitive surface that is defined by limited pivoting (e.g., a tactile actuation that causes the actuation member  1232  to substantially maintain its position with respect to the base  1220 ) and, in response, change an operating mode of the control unit  1230  and/or control a lighting load. One example of a position that is defined by limited pivoting is an area of the front surface  214  over the central axis or midpoint of the actuation member  1232 . The touch actuation (e.g., a touch input) being detected by the control unit  1230  may comprise a press-and-hold actuation (e.g., pressing and holding a finger in the area over the central axis for a non-transitory time period, such as a few seconds), a double-tap actuation (e.g., two transitory actuations of the area over the central axis executed in quick succession), a swipe gesture (e.g., consecutive contacts with multiple positions of the area over the central axis within a brief time period), and/or the like. Since the touch actuation is applied to the area over the central axis over the pivot axis of the actuation member  1232 , the touch actuation may not cause the actuation member  1232  to pivot or otherwise change its position with respect to the base portion. As such, the touch actuation applied over the area over the central axis may be clearly distinguished from a tactile actuation of the upper portion  1236  or the lower portion  1238  so as to prevent accidental triggering of a control function that is associated with the tactile actuation of the upper portion  1236  or the lower portion  1238 . It should be noted that although the description is provided herein in the context of a control device having a central pivot axis, the proposed techniques can also be used with other types of control devices including those configured to pivot about an axis located at a top or bottom end of the control device. That is, although illustrated at approximately the midpoint of the actuation member  1232 , the area may be located elsewhere on the actuation member  1232 , such as closer to the upper portion  1236  or the lower portion  1238  of the actuation member  1232  (e.g., directly above one or more of the pivot axis of the actuation member  1232 ). 
     The control unit  1230  may turn the lighting load on or off in response to receiving a touch actuation at a position of the touch sensitive surface that is defined by limiting pivoting. Further, the control unit  1230  may change an operating mode of the control unit  1230  in response to receiving a touch actuation at a position of the touch sensitive surface that is defined by limiting pivoting. One example of a change in operating mode is a change between an intensity control mode and a color control mode (e.g., a color temperature control mode and/or a full color spectrum control mode). Another example of a change in operating mode is a change between a normal operating mode and a commissioning mode that is used to associate the control unit  1230  with an electrical load. Yet another example of a change in operating mode is a change between a normal operating mode to an advanced programming mode. As described herein, an advanced programming mode may allow configuration and/or adjustment of one or more operating characteristics of the control device and/or a lighting load of the lighting control system  100 , such as a low-end trim (e.g., a minimum intensity level) and/or a high-end trim (e.g., a maximum intensity level) of the lighting load. 
     During an advanced programming mode as described herein, the front surface  1235  of the actuation member  1232  may be actuated along the light bar  1239  (e.g., a touch actuation on the touch sensitive surface) to adjust an operating characteristic (e.g., such as a low-end trim) of the control device. The light bar  1239  may be affixed to the actuation member  1232 , and as such, the light bar  1239  may be configured to move when the actuation member  1232  pivots. 
     The user may store a locked preset intensity level when in the advanced programming mode. A locked preset intensity level may be a programmable intensity level setting to which the control device will turn on a lighting load on in response to a tactile actuation of the actuation member  1232  that turns on the lighting load (e.g., a tactile actuation of the upper portion  1236  of the actuation member  1232 ), regardless of the intensity level the lighting load was set to when it was last turned off. Once the control unit  1230  has entered the advanced programming mode (e.g., by pulling out a service switch, such as an air-gap actuator as shown in  FIG.  2   , possibly in combination with other actuations), the control unit  1230  may allow the user to select between different characteristics to adjust, such as the locked preset intensity level. Once the user selects the locked preset intensity level for configuration, the control unit  1230  may indicate that the locked present intensity level configuration has been initiated (e.g., by flashing the internal light sources). Next, the control unit  1230  may receive a touch actuation from the user via the touch sensitive surface (e.g., a point actuation along the light bar  1239 ) that corresponds with an intensity level, and in response, the control unit  1230  will set the locked preset intensity level based on that touch actuation. Finally, the user may exit the advanced programming mode. Thereafter, whenever the control unit  1230  receives a tactile actuation to turn the lighting load on, the control unit  1230  will turn the lighting load on to the locked preset intensity level. 
     Further, through the advanced programming mode, the control unit  1230  may be configured to use an unlocked preset intensity level. When using the unlocked preset intensity level, the control unit  1230  may be configured to turn the lighting load on to the intensity level that was set when the lighting load was last turned off (e.g., a previous intensity level). When using the unlocked preset light level and when the lighting load is off, the control unit  1230  may illuminate one internal light source (e.g., and/or a portion of the light bar  1239 ) to a greater intensity than the rest to indicate the unlocked preset intensity level to the user. 
     The control unit  1230  may be configured to ignore touch actuations via the touch sensitive surface when the lighting load is off (e.g., disable the capacitive touch circuit when the lighting load is off). For example, the control unit  1230  may ignore touch actuations received via the touch sensitive surface for as long as the lighting load is off, and may turn on the lighting load in response to tactile actuations of the upper portion  1236  of the actuation member  1232 . However, in some instances, the control unit  1230  may turn on the lighting load in response to special touch inputs, such as long press-and-hold actuations (e.g., touch actuations that exceed a predetermined period of time) or a double-tap touch actuations. Further, the control unit  1230  may ignore touch actuations received via the touch sensitive surface during a blanking period after detecting a tactile actuation of the tactile switch to turn the lighting load on, and respond to touch actuations received via the touch sensitive surface after the blanking period. 
     The control unit  1230  may be configured to set a locked preset power level (e.g., intensity level) for the lighting load, such that the control unit  1230  is configured to automatically turn the lighting load on to the locked intensity level during a subsequent turn on event. For example, if the control unit  1230  is configured with a locked intensity level of 20% and the lighting load is in an off state, the control unit  1230  may be configured to turn the lighting load on to a 20% intensity level in response to a tactile actuation of the actuation member  1232 , for example, regardless of whether the user contacts the touch sensitive surface while actuating the actuation member  1232 . This locked preset intensity level may be configured by the user, for example, through an advanced programming mode of the control unit  1230 . 
     Further, in some examples, and prior to turning on the lighting load, the control unit  1230  may be configured to allow a user to adjust an intensity level for turning on the lighting load through a touch actuation received via the touch sensitive surface. For instance, the control unit  1230  may be configured to receive a touch actuation via the touch sensitive surface while the lighting load is in an off state, and in response, adjust the turn-on intensity level of the lighting load but not actually turn on the lighting load. Then, upon a subsequent actuation of the actuation member  1232 , the control unit  1230  may turn the lighting load on to the turn-on intensity level that was set while the lighting load was in the off state. 
     The control unit  1230  may be configured to determine whether to ignore a touch actuation received via the touch sensitive surface based on the position of the touch actuation along the touch sensitive surface. That is, the control unit  1230  may be configured to respond to touch actuations received on some positions and ignore touch actuations received on other positions of the touch sensitive surface. For example, the control unit  1230  may be configured to only respond to touch actuations that are received via the touch sensitive surface when those touch actuations are received at a position that is associated with an intensity level that is less than the default intensity level (e.g., the default intensity level being the intensity level to which the control unit  1230  would turn on the lighting load in response to a tactile actuation of the actuation member  1232 , such as a locked present intensity level, a previous intensity level, and/or a turn-on intensity level). Such a feature may be helpful if the control unit  1230  controls a lighting load used in a hallway or bathroom to ensure that the lighting load does not turn on to an intensity level that would disrupt the user (e.g., be too bright for the user) in the middle of the night. Further, in some examples, the control unit  1230  may also take into consideration the time when the touch actuation is received. As such, the control unit  1230  may determine whether to ignore a touch actuation received via the touch sensitive surface based on the position of the touch actuation along the touch sensitive surface and the time of day and/or day of the week (e.g., the control unit  1230  may ignore touch actuation at positions that correspond to certain intensity levels at nighttime). 
     The control unit  1230  may be configured to change operating characteristics (e.g., the number and/or the length of blanking periods, the types and/or characteristics of filtering modes, etc.) and/or the operating mode of the control unit  1230  (e.g., intensity control mode, color control mode, advanced programming mode, commissioning mode, etc.) in a variety of manners. For example, the control unit  1230  may change operating characteristics and/or operating mode through the use of the advance programming mode, in response to receiving a touch actuation at a position of the touch sensitive surface that is defined by limiting pivoting (e.g., the central axis of the actuation member  1232 ), based on the time of day and/or day of the week (e.g., time clock information), and/or based on a learning algorithm. For instance, once in the advanced programming mode, the control unit  1230  may be configured to change between operating modes (e.g., intensity control mode and color control mode) and/or change an operating characteristics (e.g., the number and/or the length of blanking periods, the types and/or characteristics of filtering modes, etc.). Alternatively or additionally, the control unit  1230  may change between operating modes and/or change an operating characteristics in response to receiving an input at a position of the touch sensitive surface that is defined by limiting pivoting. Further, the control unit  1230  may change between operating modes and/or change an operating characteristics based on the time of day and/or the day of the week. 
     Further, the control unit  1230  may change operating characteristics and/or operating mode based on a learning algorithm. As another example, the control unit  1230  may be configured to learn that when the control unit  1230  receives an input (e.g., a tactile actuation) to turn a lighting load on at certain times of day, the user subsequently reduces the intensity level to a particular level (e.g., down from the turn-on intensity level to 25% intensity), and as a result, the control unit  1230  may be configured to initially turn the lighting load on to 25% intensity when the control unit  1230  receives an input to turn on the lighting load at that time of day. 
     As another example, the control unit  1230  may be configured to adjust the length of a blanking period based on a learning algorithm (e.g., the blanking period that occurs after (e.g., in response to) a touch actuation and/or the blanking period that occurs after (e.g., in response to) a tactile actuation). For instance, the control unit  1230  may determine that the blanking period is too short, and in response, lengthen the blanking period to avoid unintentional operations that are caused by accidental touch actuations received via the touch sensitive surface. One way that the control unit  1230  may determine that the blanking period is too short is by recognizing a series of events that indicate that an accidental touch actuation was received via the touch sensitive surface. For example, after turning the lighting load on in response to a first actuation (e.g., a touch actuation) of the actuation member  1232  (e.g., the touch sensitive surface), the control device may receive (e.g., consistently receive) a second actuation (e.g., a touch actuation) that undoes or adjusts the control initiated by the first actuation (e.g., adjusts the intensity level). The control device may determine that the user had intended to apply a tactile actuation to the actuation member  1232  and lengthen the blanking period after receiving touch actuations (e.g., the blanking period that occurs after (e.g., in response to) a touch actuation). In addition, after turning the lighting load off in response to a tactile actuation of the actuation member  1232 , the control device then determine that it receives two subsequent inputs via the touch sensitive surface (e.g., touch actuations)—a first input that controls the lighting load in some manner (e.g., turns the lighting load on) and a second input that undoes the control initiated by the first input (e.g., turns the lighting load off). Accordingly, the control unit  1230  may determine that such a series of events occurs often, and in response, lengthen the blanking period after receiving tactile actuations (e.g., the blanking period that occurs after (e.g., in response to) a tactile actuation). 
     When a user input (e.g., a touch actuation) is applied to an area of the front surface  1235  located away from the first and second tactile switches  1245   a ,  1245   b  (e.g., the central axis of the actuation member  1232 ), the first and second tactile switches  1245   a ,  1245   b  may not be actuated and the control unit  1230  may be configured to enter an advanced programming mode (e.g., as described herein) or to change operating modes (e.g., switch from an intensity control mode to a color control mode) in response to the touch actuation. For example, the area may be located on the front surface  214  furthest away from the first and second tactile switch  1245   a ,  1245   b . It should be noted that although the touch actuation is described as being applied to the area over the central axis of the actuation member  1232 , such touch actuation may also be applied in other positions of the front surface  1235  so long as those positions are sufficiently spaced away (e.g., furthest away) from the tactile switches to prevent accidental triggering of an unintended control function. 
     The distance between the touch sensitive surface (e.g., the front surface  1235  of the actuation member  1232 ) and the receiving capacitive touch pads on the printed circuit board  1244  may not be uniform over the length of the actuation member  1232  (e.g., the actuation member  1232  may not have a uniform thickness, and/or the actuation member  1232  and the printed circuit board  1244  may be shaped differently). For example, although illustrated in a bent shape having the fold  1247 , printed circuit board  1244  may be straight in some examples. In situations where the distance between the touch sensitive surface (e.g., the front surface  1235  of the actuation member  1232 ) and the receiving capacitive touch pads on the printed circuit board  1244  is not uniform, the printed circuit board  1244  may use different voltage thresholds V TH  for one or more of the capacitive touch pads, for example, to ensure that the printed circuit board  1244  reacts in a similar or identical manner to comparable touches at different positions along the length of touch sensitive surface of the actuation member  1232 . As described in more detail below, the printed circuit board  1244  may set the respective voltage thresholds V TH  of the capacitive touch pads. 
     For example, the printed circuit board  1244  may compare a measured voltage to a voltage threshold V TH  and generate an output signal V OUT  that may indicate when the measured voltage exceeds the voltage threshold V TH . The printed circuit board  1244  may use smaller voltage thresholds V TH  for the capacitive touch pads that are further separated from the touch sensitive surface as compared to the voltage thresholds V TH  that are used for the capacitive touch pads that are separated from the touch sensitive surface by a lesser distance. Accordingly, the printed circuit board  1244  may offset the impact of the varying distances between of the front surface  1235  of the actuation member  1232  and the printed circuit board  1244  by using varying voltage thresholds V TH  for the capacitive touch pads. 
     The illustrated control unit  1230  may be battery-powered. The battery  1280  (e.g., the illustrated coin cell battery) may be placed in electrical communication with the circuitry mounted to the printed circuit board  1244 , for instance to power the capacitive touch regions, the control circuit, the wireless communication circuit, and/or other circuitry of the control unit  1230 . 
     The control unit  1230  may be configured to receive the battery holder  1270 . The battery holder  1270  may include a housing  1274 , a retaining clip  1272 , positive battery contact  1281 , and a negative battery contact  1282  (e.g., a backplate). The positive battery contact  1281  may be a positive electrical contact and the negative battery contact  1282  may be a negative electrical contact. For example, the positive battery contact  1281  and the negative battery contact  1282  may be connected to the housing  1274 . The battery holder  1270  may be configured to retain the battery  1280  therein. The battery holder  1270  may define a cavity  1277 . For example, the housing  1274  and the negative battery contact  1282  may define the cavity  1277 . The negative battery contact  1282  may be configured to attach to the housing  1274 . The negative battery contact  1282  may be configured to define a rear surface of the cavity  1277 . The cavity  1277  may be configured to receive the battery  1280 . The retaining clip  1272  may be configured to secure the battery  1280  within the cavity  1277 . The retaining clip  1272  may define a pivot clip  1271  and a locking clip  1273 . The pivot clip  1271  may pivotally mount the retaining clip  1272  to the battery holder  1270 . For example, the retaining clip  1272  may pivot using the pivot clip  1271 . The locking clip  1273  may be configured to secure the retaining clip  1272  to the housing  1274  such that the battery  1280  is retained therein. The pivot clip  1271  may comprise a retention tab  1279  that may retain the pivot clip  1271  in the battery holder  1270  when the retaining clip  1272  is moved to the open position. 
     The battery holder  1270  may be configured to be installed within the void  1248  defined by the control unit  1230  (e.g., the housing  1234 ). For example, the void  1248  may be configured to receive the battery holder  1270 . The battery holder  1270  may be configured to retain the battery  1280  therein. The battery holder  1270  may include attachment clips  1276 . The attachment clips  1276  may be c-clips (e.g., such as right-angle c-clips). The attachment clips  1276  may be configured to rotatably attach to the pivot bar  1250 . For example, the attachment clips  1276  may be configured to pivot about the pivot bar  1250 , for example, as the battery holder is moved between the first position and the second position. The pivot bar  1250  may define a pivot axis. The battery holder  1270  may be configured to pivot about the pivot axis. The pivot axis may be located at a midpoint of the control unit  1230 . Alternatively, the pivot bar  1250  may be a pin (e.g., a rod) and the battery holder  1270  may comprise fully closed loops rather than the attachment clips  1276 . The pin may be slid into the closed loops of the battery holder and then the ends of the pin may be attached to the housing  1234 . 
     The battery holder  1270  may be configured to electrically connect the battery  1280  to the control unit  1230  (e.g., the printed circuit board  1244 ) for powering the circuitry of the control unit  1230 . The battery holder  1270  may be configured to maintain electrical contact between the battery  1280  and the printed circuit board  1244  when the battery holder  1270  is moved between the first position and the second position. For example, the positive battery contact  1281  and the negative battery contact  1282  of the battery holder  1270  may be configured to be electrically connected to a positive terminal and a negative terminal of the battery  1280 , respectively, when the battery is received in the cavity  1277 . The positive battery contact  1281  may operate as a spring that is biased towards the battery  1280  when the battery is received in the cavity  1277 . 
     The control unit  1230  may include a flexible cable (not shown) that is attached (e.g., mechanically and electrically connected) to the printed circuit board  1244 . The flexible cable may be attached (e.g., mechanically and electrically connected) to the battery holder  1270 . The flexible cable may comprise at least two electrical conductors (not shown) for electrically connecting the circuitry of the control unit  1230  on the printed circuit board  1244  to the positive and negative terminals of the battery  1280 . For example, a first one of the electrical conductors of the flexible cable may be electrically connected to positive battery contact  1281  and a second one of the electrical conductors of the flexible cable may be electrically connected to the negative battery contact  1282 . Alternatively, the retaining clip  1272  may operate as a positive battery contact of the battery holder  1270 . 
     It should be appreciated that electrical connection between the battery  1280  and the printed circuit board  1244  may be achieved in other ways. For example, the battery holder  1270  may abut a first post (not shown) on the control unit  1230  in the second position and may abut a second post (not shown) on the control unit  1230  in the first position. The first post and the second post may be configured to provide the electrical connection between the battery  1280  and the printed circuit board  1244 . The first post may be proximate to the upper wall  1241  and the second post may be proximate to the lower wall  1242 . 
     The battery holder  1270  may be configured to adjust the location of the battery  1280  within the control unit  1230 . For example, the location of the battery  1280  may be adjusted based on the position of the paddle actuator  1292  when power is being delivered to the electrical load(s) associated with the mechanical switch  1290 . The battery holder  1270  may be operable between a first position and a second position. For example, the battery holder  1270  may be configured to be pivoted between the first position and the second position. The first position may be defined as the battery holder  1270  proximate to the lower wall  1242  (e.g., a lower portion of the void  1248 ). For example, the battery holder  1270  may be in the lower portion of the void  1248  when the battery holder  1270  is in the first position. The second position may be defined as the battery holder  1270  proximate to the upper wall  1241  (e.g., an upper portion of the void  1248 ). For example, the battery holder  1270  may be in the upper portion of the void  1248  when the battery holder  1270  is in the second position. 
     The control unit  1230  (e.g., the housing  1234 ) may define stops  1256   a ,  1256   b  in the upper portion and the lower portion of the void  1248 . The stops  1256   a ,  1256   b  may extend into the void  1248  from the upper wall  1241  and the lower wall  1242 . The stops  1256   a ,  1256   b  may be configured to prevent the battery holder  1270  from pivoting beyond the first position and the second position, respectively. The stops  1256   a ,  1256   b  may be configured to prevent the battery holder  1270  from abutting the printed circuit board  1244 . The stops  1256   a ,  1256   b  may be configured to snap into an outer edge  1257  of the housing  1274  of the battery holder  1270  when the battery holder  1270  is in the first position or the second position. The control unit  1230  may be configured to be attached to the base  1220  with the light bar  1239  located on a predetermined side of the control unit (e.g., the right side of the control unit as shown in  FIG.  10   ), for example, such that the light bar  1239  may be illuminated to indicate the amount of power presently being delivered to the electrical load. The control unit  1230  may be configured to be attached to base  1220  with the light bar  1239  located on a predetermined side of the control unit independent of a position of the paddle actuator  1292  of the mechanical switch  1290  (e.g., whether the upper portion or the lower portion of the paddle actuator  1292  is protruding from the bezel  1293 ). For example, the control unit  1230  may be configured such that the battery  1280  can be pivoted between the first position and the second position based on whether the upper portion or the lower portion of the paddle actuator  1292  is protruding from the bezel  1293 . 
     The void  1248  of the control unit  1230  may be configured to receive a portion of the paddle actuator  1292  of the mechanical switch  1290  when the control unit  1230  is attached to the base  1220 . The control unit  1230  may define separate portions of the void  1248 , for example, the upper portion and the lower portion. When the mechanical switch  1290  is in a first orientation (e.g., when the upper portion of the paddle actuator  1292  is protruding from the bezel  1293 ), the upper portion may receive the upper portion of the paddle actuator  1292  and the lower portion may receive the battery holder  1270 . When the mechanical switch  1290  is in a second orientation (e.g., when the lower portion of the paddle actuator  1292  is protruding from the bezel  1293 ), the lower portion may receive the portion of the lower portion of the paddle actuator  1292  and the upper portion may receive the battery holder  1270 . 
     In some installations, the control unit  1230  may not be offset from the paddle actuator  1292  of the mechanical switch  1290  by enough distance when control unit  1230  is mounted to the base  1220 , and the control unit  1230  may even contact the paddle actuator  1292 . In this scenario, the control unit  1230  may cause the paddle actuator  1292  of the mechanical switch  1290  to change from the on position to the off position when a user actuates the actuation member  1232 . The control unit  1230  (e.g., the housing  1234 ) may define flanges in the upper portion and the lower portion of the void  1248 . The flanges may extend into the void  1248  from the opposed side walls  1243 . When the control unit  1230  is being mounted onto the base  1220  during installation of the remote control device  1200 , the flanges  1268  may contact the paddle actuator  1292  to indicate to the installer that the control unit  1230  may not be offset from the paddle actuator  1292  by enough distance. The installer may then install the spacer  1210  (or multiple spacers) onto the base  1220  to provide additional distance between the control unit  1230  and the paddle actuator  1292 . 
       FIG.  16    is a simplified block diagram of an example control device  300  (e.g., a dimmer switch) that may be deployed as, for example, the dimmer switch  110  of the lighting control system  100 , the control device  200  of  FIGS.  2 - 7   , and/or the control device  280  of  FIGS.  8 - 9   . The control device  300  may include a hot terminal H that may be adapted to be coupled to an AC power source  302 . The control device  300  may include a dimmed hot terminal DH that may be adapted to be coupled to an electrical load, such as a lighting load  304 . The control device  300  may include a controllably conductive device  310  coupled in series electrical connection between the AC power source  302  and the lighting load  304 . The controllably conductive device  310  may control the power delivered to the lighting load. The controllably conductive device  310  may include a suitable type of bidirectional semiconductor switch, such as, for example, a triac, a field-effect transistor (FET) in a rectifier bridge, two FETs in anti-series connection, or one or more insulated-gate bipolar junction transistors (IGBTs). An air-gap switch  329  may be coupled in series with the controllably conductive device  310 . The air-gap switch  329  may be opened and closed in response to actuations of an air-gap actuator (e.g., not shown). When the air-gap switch  329  is closed, the controllably conductive device  310  is operable to conduct current to the load. When the air-gap switch  329  is open, the lighting load  304  is disconnected from the AC power source  302 . 
     The control device  300  may include a dimmer control circuit  314 . The dimmer control circuit  314  may include one or more of a processor (e.g., a microprocessor), a microcontroller, a programmable logic device (PLD), a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), or any suitable controller or processing device. The dimmer control circuit  314  may be operatively coupled to a control input of the controllably conductive device  310 , for example, via a gate drive circuit  312 . The dimmer control circuit  314  may be used for rendering the controllably conductive device  310  conductive or non-conductive, for example, to control the amount of power delivered to the lighting load  304 . The dimmer control circuit  314  may receive a control signal representative of the zero-crossing points of the AC mains line voltage of the AC power source  302  from a zero-crossing detector  316 . The dimmer control circuit  314  may be operable to render the controllably conductive device  310  conductive and/or non-conductive at predetermined times relative to the zero-crossing points of the AC waveform using a phase-control dimming technique. The dimmer control circuit  314  may be configured to control the magnitude of a load current conducted through the lighting load(s) so as to control an intensity level of the lighting load  304  across a dimming range between a low-end intensity level L LE  and a high-end intensity level L HE . For example, the dimmer control circuit  314  may be configured to control the intensity level of the lighting load  304  to a number N INT  (e.g.,  255 ) of intensity levels between the low-end intensity level L LE  and the high-end intensity level L HE . 
     The control device  300  may include a memory  318 . The memory  318  may be communicatively coupled to the dimmer control circuit  314  for the storage and/or retrieval of, for example, operational settings, such as, lighting presets and associated preset light intensities. The memory  318  may be implemented as an external integrated circuit (IC) or as an internal circuit of the dimmer control circuit  314 . The control device  300  may include a power supply  320 . The power supply  320  may generate a direct-current (DC) supply voltage V CC  for powering the dimmer control circuit  314  and the other low-voltage circuitry of the control device  300 . The power supply  320  may be coupled in parallel with the controllably conductive device  310 . The power supply  320  may be operable to conduct a charging current through the lighting load  304  to generate the DC supply voltage V CC . 
     The dimmer control circuit  314  may be responsive to user inputs received from actuators  330  and/or a touch sensitive device  350 . It should be appreciated that in examples where the control device is a dual-dimmer, the control device may include two touch sensitive devices  350  or a single touch sensitive device that is responsive to two sets of capacitive touch elements, such as capacitive touch pads. The dimmer control circuit  314  may control the controllably conductive device  310  to adjust the intensity level of the lighting load  304  in response to the user inputs (e.g., tactile actuations and/or touch actuations) received via the actuators  330  and/or the touch sensitive device  350 . The dimmer control circuit  314  may receive respective input signals from the actuators  330  in response to tactile actuations of the actuators  330  (e.g., in response to movements of the actuators  330 ). For example, the actuators  330  may be actuated in response to tactile actuations of an upper portion and/or a lower portion of the actuation member of the control device. 
     The touch sensitive device  350  may be configured to detect touch actuations (e.g., point actuations and/or gestures, where, for example, the gestures may be effectuated with or without physical contacts with the touch sensitive device  350 ), and provide respective output signals V OUT  to the dimmer control circuit  314  indicating the touch actuations (e.g., indicating a position of one or more touch actuations). Further, the touch sensitive device  350  may detect a touch actuation (e.g., a press-and-hold actuation) applied to an area of the front surface of the actuation member that resides over the pivot axis and cause the dimmer control circuit  314  to enter an advanced programming mode, as described herein. The touch sensitive device  350  may also detect a touch actuation of the front surface along the light bar and cause the dimmer control circuit  314  to adjust the amount of power delivered to the lighting load  304  accordingly. The dimmer control circuit  314  may be configured to translate the input signals received from the actuators  330  and/or the output signals V OUT  received from the touch sensitive device  350  into control data (e.g., one or more control signals). The control circuit  314  may use the control data to drive a drive circuit  312  to control a controllably conductive device  310  to adjust the amount of power delivered to the lighting load  304  and/or cause the control data to be transmitted to the lighting load  304  or a central controller of the load control system. 
     The touch sensitive device  350  may include a capacitive touch circuit  352  and a user interface control circuit  354  (e.g., which may be an example of the capacitive touch controller  252 ). The capacitive touch circuit  352  that comprises one more capacitive touch elements. For example, the capacitive touch circuit  352  may comprise one or more capacitive touch pads, such as the receiving capacitive touch pads  244  and/or the proximity capacitive touch pad  245  mounted to the capacitive touch PCB  240  of the control device  200 . In addition, the capacitive touch circuit  352  may comprise one or more capacitive transmission traces, such as the first and second transmission traces  246 ,  248  on the capacitive touch PCB  240  of the control device  200 . The capacitive touch circuit  352  may provide one or more capacitive receive signals V RX-A -V RX-E  from the capacitive touch pads of the capacitive touch circuit  352  (e.g., from regions A-E of the receiving capacitive touch pads  242  mounted to the capacitive touch PCB  240  of the control device  200 ), where each capacitive receive signal V RX-A -V RX-E  indicates the capacitance of a capacitive touch pad. Further, the capacitive touch circuit  352  may provide a proximity sense signal V PROX  to the user interface control circuit  354  (e.g., based on the proximity capacitive touch pad  245  mounted to the capacitive touch PCB  240  of the control device  200 ). 
     The user interface control circuit  354  may include one or more of a processor (e.g., a microprocessor), a microcontroller, a programmable logic device (PLD), a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), or any suitable controller or processing device. The user interface control circuit  354  may include a memory and/or may use the memory  318 . The user interface control circuit  354  may be configured to determine or detect a change in the capacitances of the capacitive touch pads of the capacitive touch circuit  352  (e.g., due to a user&#39;s finger actuating the front surface  214  of the actuation member  210 ), and generate the output signal V OUT  in accordance with the change in capacitance of the capacitive touch pads. The output signal V OUT  may indicate a position of a touch actuation along the front surface of the actuation member (e.g., over the light bar  220 ). As noted above, the user interface control circuit  354  may receive one or more capacitive receive signals V RX-A -V RX-E  from the capacitive touch pads of the capacitive touch circuit  352  (e.g., from regions A-E of the receiving capacitive touch pads  242  mounted to the capacitive touch PCB  240  of the control device  200 ), where each capacitive receive signal V RX-A -V RX-E  indicates the capacitance of a capacitive touch pad. 
     The user interface control circuit  354  may be configured to determine the position of the touch actuation along the front surface of the actuation member (e.g., along the light bar  220 ) in response to the receive signals V RX-A -V RX-E  generated by the receiving capacitive touch pads. In response, the user interface control circuit  354  may generate and provide the output signal V OUT  to the dimmer control circuit  314 . For example, the user interface control circuit  354  may be configured to charge capacitances of the capacitive touch pads of the capacitive touch circuit  352 . For example, although not illustrated, the capacitive touch pads of the capacitive touch circuit  352  may be coupled to user interface control circuit  354  via a capacitive transmitting circuit (not shown) and/or a capacitive receiving circuit (not shown). The user interface control circuit  354  may be configured to control the capacitive transmitting circuit to charge capacitances of the capacitive touch pads (e.g., the capacitive touch pads  242 ) of the capacitive touch circuit  352 . For example, the capacitive transmitting circuit may be configured to pull the transmission trace (e.g., the transmission trace  244 ) of the capacitive touch circuit  352  up towards the supply voltage V CC  to charge the capacitances of the capacitive touch pads. 
     The user interface control circuit  354  may step through each of the capacitive touch pads of the capacitive touch circuit  352  and process the capacitive receive signals V RX-A -V RX-E  to detect a change in the capacitance of the respective capacitive touch pad. For example, the user interface control circuit  354  may periodically charge the capacitance of each of the capacitive touch pads of the capacitive touch circuit  352  and then discharge the capacitance of the respective touch pad into a capacitor (not shown) of the user interface control circuit  354  (e.g., which may have a much larger capacitance than the capacitance of each of the capacitive touch pads of the capacitive touch circuit  352 ). The user interface control circuit  354  may be configured to compare the voltage across the capacitor of the touch sensitive device  350  to a voltage threshold V TH  and generate an output signal V OUT , which may indicate when the voltage across the capacitor of the touch sensitive device  350  exceeds the voltage threshold V TH . For example, the user interface control circuit  354  may charge and discharge the capacitance of each capacitive touch pad a predetermined number of time (e.g., 500 times) during a sensing interval (e.g., 500 μsec) before moving on the next capacitive touch pad of the capacitive touch circuit  352 . 
     The user interface control circuit  354  may be configured to determine a count N CAP  that indicates how many times the capacitance of the respective capacitive touch pad was charged and discharged before the voltage across the capacitor of the touch sensitive device  350  exceeds the voltage threshold V TH . The count N CAP  may indicate the present capacitance of the respective capacitive touch pad of the capacitive touch circuit  352 . The count N CAP  for each of the capacitive touch pads of the capacitive touch circuit  352  may represent a sample of the present capacitance of the respective touch pad during the preceding sensing interval. The user interface control circuit  354  may be configured to process the count N CAP  to determine the present capacitance of the respective touch pad of the capacitive touch circuit  352  using a respective baseline count N BL  for each of the capacitive touch pads of the capacitive touch circuit  352 . The baseline count N BL  may indicate an idle capacitance of each of the capacitive touch pads when the front surface of the actuation member (e.g., the light bar) is not being actuated. The user interface control circuit  354  may be configured to determine the respective baseline counts N BL  for each of the capacitive touch pads of the capacitive touch circuit  352  when the front surface of the actuation member is not being actuated. For example, the baseline count N BL  may be a long-term average of the count N CAP  determined by the user interface control circuit  354  from the capacitive receive signals V RX-A -V RX-E . 
     After stepping through each of the capacitive touch pads of the capacitive touch circuit  352  (e.g., after a round of capacitive sensing of the capacitive touch pads), the user interface control circuit  354  may process the determined counts N CAP  for each of the respective capacitive touch pads of the capacitive touch circuit  352  to detect a touch actuation. The user interface control circuit  354  may be configured to determine a change Δ CAP  in the count (e.g., which may indicate the capacitance of each of the capacitive touch pad of the capacitive touch circuit  352 ) by determining the difference between the respective baseline count N BL  from the present count N CAP  of the respective capacitive touch pad, e.g., Δ CAP =|N CAP −N BL |. The user interface control circuit  354  may be configured to determine that capacitive sensitive surface (e.g., the light bar) is being actuated when at least one of the changes Δ CAP  in count exceeds a capacitance-change threshold TH CAP , which may represent a 0.5% to 1% change in the capacitance, for example. 
     The user interface control circuit  354  may be configured to determine a number N TOUCH-IN  of times (e.g., a number of consecutive rounds of capacitive sensing) that the change Δ CAP  in count for one of the capacitive touch pads exceeds the capacitance-change threshold TH CAP . The user interface control circuit  354  may be configured to enter an active touch mode when the number N TOUCH-IN  exceeds a touch-in threshold TH TOUCH-IN  (e.g., such as two, three, four, five, six, seven, or eight). For example, the user interface control circuit  354  may detect a touch actuation when the number N TOUCH-IN  exceeds a touch-in threshold TH TOUCH-IN . When in the active touch mode, the user interface control circuit  354  may be configured to determine a number N TOUCH-OUT  of times (e.g., a number of consecutive rounds of capacitive sensing) that the change Δ CAP  in count for one of the capacitive touch pads does not exceed the capacitance-change threshold TH CAP . The user interface control circuit  354  may be configured to exit the active touch mode when the number N TOUCH-OUT  exceeds a touch-out threshold TH TOUCH-OUT . 
     While in the active touch mode, the user interface control circuit  354  may be configured to determine the position of the touch actuation along the touch sensitive surface (e.g., the light bar) in response to ratios of the changes Δ CAP  in the count for each of the capacitive touch pads of the capacitive touch circuit  352  (e.g., in response to the receive signals V RX-A — V RX-E  generated by the receiving capacitive touch pads). For example, the ratio of the change Δ CAP  in the count for region B to the change Δ CAP  in the count for region C of the receiving capacitive touch pads  244  of the control device  200  may indicate a position of a touch actuation along the light bar  220  between the regions B and C. 
     Even though the user interface control circuit  354  may detect that the touch sensitive surface is being actuated in response to the changes Δ CAP  in counts for one or more of the receiving capacitive touch pads of the capacitive touch circuit  352  (e.g., in response to the receive signals V RX-A -V RX-E ), the user may not actually be touching the front surface of the actuation member (e.g., the user is not touching a portion of the front surface associated with touch actuations, such as the user not touching the light bar  220  but contacting another portion of the front surface and not intending to control the load). In some examples, the user interface control circuit  354  may be configured to determine if the touch sensitive surface (e.g., the light bar) is not being actuated (e.g., the user&#39;s finger has moved too far to the left) in response to a change Δ CAP-PROX  in count for the proximity capacitive touch pad of the capacitive touch circuit  352 . If the user interface control circuit  354  determines that the user&#39;s finger is closer to the proximity capacitive touch pad of the capacitive touch circuit  352 , the user interface control circuit  354  may cease processing the ratios of the changes Δ CAP  in the count for each of the receiving capacitive touch pads of the capacitive touch circuit  352  to determine the position of the actuation along the light bar (e.g., the user interface control circuit  354  may ignore the touch actuation if it is closer to the proximity capacitive touch pad). The user interface control circuit  354  may start determining the position of the touch actuation along the touch sensitive surface again when the change Δ CAP-PROX  in the count for the proximity capacitive touch pad of the capacitive touch circuit  352  indicates that the user&#39;s finger is close to the light bar. 
     The user interface control circuit  354  may provide an output signal V OUT  to the dimmer control circuit  314  in response to detecting a touch actuation along the touch sensitive surface of the control device  300  (e.g., in response to detecting a touch actuation along the light bar  220 ). The output signal V OUT  may indicate a position of the touch along the front surface of the actuation member. The dimmer control circuit  314  may be configured to translate the output signal V OUT  into control data (e.g., one or more control signals) for controlling one or more electrical loads. For example, the dimmer control circuit  314  may use the control data to drive a drive circuit  312  to control a controllably conductive device  310  to adjust the amount of power delivered to the lighting load  304  and/or may cause the control data to be transmitted to the lighting load  304 , another load control device, and/or a system controller of the load control system via a communication circuit  322 . 
     The user interface control circuit  354  may generate a touch actuation signal V ACT  that may indicate that a touch is present along the touch sensitive surface of the actuation member of the control device. The user interface control circuit  354  may provide the touch actuation signal V ACT  to the dimmer control circuit  314 . For example, the user interface control circuit  354  may drive the touch actuation signal V ACT  high upon detecting a touch actuation along the touch sensitive surface to indicate that the control device is operating in active touch mode, and otherwise drive the touch activation signal V ACT  low. 
     Although described with reference to the user interface control circuit  354 , it should be appreciate that in some examples the control device  300  may include a single control circuit, such as the dimmer control circuit  314 , and the processing performed by the user interface control circuit  354  may be performed by the dimmer control circuit  314 . 
     The control device  300  may comprise the wireless communication circuit  322 . The wireless communication circuit  322  may include for example, a radio-frequency (RF) transceiver coupled to an antenna for transmitting and/or receiving RF signals. The wireless communication circuit  322  may also include an RF transmitter for transmitting RF signals, an RF receiver for receiving RF signals, or an infrared (IR) transmitter and/or receiver for transmitting and/or receiving IR signals. The wireless communication circuit  322  may be configured to transmit a control signal that includes the control data (e.g., a digital message) generated by the dimmer control circuit  314  to the lighting load  304 . As described herein, the control data may be generated in response to a user input (e.g., a point actuation or a gesture) to adjust one or more operational aspects of the lighting load  304 . The control data may include a command and/or identification information (e.g., such as a unique identifier) associated with the control device  300 . In addition to or in lieu of transmitting the control signal to the lighting load  304 , the wireless communication circuit  322  may be controlled to transmit the control signal to a central controller of the lighting control system. 
     The dimmer control circuit  314  may be configured to illuminate visual indicators  360  (e.g., LEDs) to provide feedback of a status of the lighting load  304 , in response to receiving indications of actuations of capacitive touch pads, to indicate a status of the control device  300 , and/or to assist with a control operation (e.g., to provide a color gradient for controlling the color of the lighting load  304 , to present backlit virtual buttons for preset, zone, or operational mode selection, etc.). The visual indicators  360  may be configured to illuminate a light bar (e.g., the light bar  220 ) and/or to serve as indicators of various conditions. As one example, touch sensitive device  350  may be used to allow a user to control dimming of a lighting load, with visual indicators  360 , through illumination of light bar  220 , showing the degree of dimming (e.g., increased illumination of the light bar to show increased intensity of the load). 
       FIG.  17    is a block diagram of an example control device  1300  (e.g., a remote control device), which may be deployed as the remote control device  1200  of  FIGS.  10 - 15   . Further, it should be appreciate that the control device  1300  may be deployed as the remote control device  112 , the wall-mounted remote control device  114 , the tabletop remote control device  116 , and/or the handheld remote control device  118  of the lighting control system  100  of  FIG.  1   . The control device  1300  may include a control circuit  1310 , one or more actuators  1312  (e.g., buttons and/or switches), a touch sensitive device  1314 , a wireless communication circuit  1316 , one or more LEDs  1318 , a memory  1320 , and/or a battery  1322 . The memory  1320  may be configured to store one or more operating parameters (e.g., such as a preconfigured color scene or a preset light intensity level) of the control device  1300 . The battery  1322  may provide power to one or more of the components shown in  FIG.  17   . 
     The actuators  1312  (e.g., a mechanical tactile switches) that may be actuated in response to a tactile actuation of one or more respective buttons of the control device (e.g., the actuation member  1232  of the remote control device  1200 ). The actuators  1312  may be configured to send respective input signals to the control circuit  1310  in response to actuations of the buttons. The touch sensitive device  1314  may be an example of the touch sensitive device  350 , and as such, the touch sensitive device  1314  may perform one or more of the functions described with references to the touch sensitive device  350 . Further, the control circuit  1310  may perform one or more of the functions described with reference to the dimmer control circuit  314  (e.g., with the exclusion of controlling a drive circuit or performing zero-cross detection). 
     The touch sensitive device  1314  may include a capacitive or resistive touch element arranged behind, for example, the actuation member  1232  of the remote control device  1200 . The touch sensitive device  1314  may be responsive to a touch actuation of, for example, the touch sensitive surface the actuation member  1232 . The touch sensitive device  1314  may be configured to detect touch actuations, such as point actuations and/or gestures (e.g., the gestures may be effectuated with or without physical contacts with the touch sensitive device  1314 ) and provide respective output signals (e.g., such as the output signal V OUT ) to the control circuit  1310  indicating the detection (e.g., indicating a position of the touch actuation along the touch sensitive surface of the actuation member  1232 ). 
     The control circuit  1310  may be configured to translate the input signals provided by the actuators  1312  and/or the output signals provided by the touch sensitive device  1314  into control data (e.g., digital control signals) for controlling one or more electrical loads. The control circuit  1310  may cause the control data (e.g., digital control signals) to be transmitted to the electrical loads via the wireless communication circuit  1316 . For example, the wireless communication circuit  1316  may transmit a control signal including the control data to the one or more electrical loads or to a central controller of the concerned load control system. The control circuit  1310  may control the LEDs  1318  to illuminate a visual indicator (e.g., the light bar  1239  of the remote control device  1200 ) to provide feedback about various conditions. 
     It should be appreciated that the example remote control device  1200  illustrated and described herein may provide a simple retrofit solution for an existing switched control system and may ease the installation of a load control system or enhance an existing load control system installation. A load control system that integrates one or more remote control devices  1200  may provide energy savings and/or advanced control features, for example without requiring any electrical re-wiring and/or without requiring the replacement of any existing mechanical switches. 
       FIG.  18    is a flowchart of an example control procedure  400  that may be executed by a control circuit of a control device (e.g., a control circuit of the control device  200 , a control circuit of the control device  280 , a control circuit of the control device  1200 , any combination of the dimmer control circuit  314  or the user interface control circuit  354  of the control device  300 , and/or any combination of the control circuit  1310  or a control circuit of the touch sensitive device  1314  of the control device  1300 ) in response to a tactile actuation of an actuator member to turn a lighting load (e.g., the lighting load  304 ) on and/or off. For example, the control circuit may execute the control procedure  400  at  410  in response to a tactile actuation of an upper portion or a lower portion of an actuation member (e.g., the upper portion  216  or the lower portion  218  of the actuation member  210 , the upper portion or the lower portion of the actuation member  284 , and/or the upper portion  1236  or the lower portion  1238  of the actuation member  1232 ) that causes the actuation member to pivot to actuate a tactile switch (e.g., one of the tactile switches  262 ,  264 , or one of the tactile switches  1245   a ,  1245   b ). 
     If an on actuator was actuated at  412  (e.g., the upper portion  216  of the actuation member  210  was pressed to actuate the first tactile switch  262 ), the control circuit may determine if the lighting load is presently on at  414 . If so, the control procedure  400  may simply exit. If the lighting load is off at  414 , the control circuit may turn on the lighting load at  416  (e.g., by controlling the controllably conductive device  310  and/or by sending a message, such as a digital message, to a load control device to control the lighting load). For example, the dimmer control circuit  314  of the control device  300  may control the controllably conductive device  310  to turn on the lighting load at  416 . In addition, the control circuit  1310  of the control device  1300  may transmit a message including control data for turning on the lighting load the lighting load via the wireless communication circuit  1316  at  416 . If the on actuator was not actuated at  412 , but an off actuator was actuated at  418  (e.g., the lower portion  218  of the actuation member  210  was pressed to actuate the second tactile switch  264 ), the control circuit may determine if the lighting load is presently off at  420 . If so, the control procedure  400  may simply exit. If the lighting load is on at  420 , the control circuit may turn off the lighting load at  422  (e.g., by controlling the controllably conductive device  310  and/or by sending a message, such as a digital message, to a load control device to control the lighting load). For example, the dimmer control circuit  314  of the control device  300  may control the controllably conductive device  310  to turn off the lighting load at  422 . In addition, the control circuit  1310  of the control device  1300  may transmit a message including control data for turning off the lighting load the lighting load via the wireless communication circuit  1316  at  422 . 
     The control device may also comprise a touch sensitive device (e.g., the touch sensitive device  350 , and in examples where the control device is a dual dimmer, the control device may include multiple touch sensitive devices) that is responsive to actuations of a touch sensitive surface of the actuator (e.g., actuations of the touch sensitive surface of the  210  along the light bar  220 ). After turning the lighting load on at  416  or off at  422 , the control circuit may disable the touch sensitive device at  424 . That is, after turning the lighting load on at  416  or off at  422 , the control circuit may ignore inputs receives via the touch sensitive device at  424  (e.g., not respond to inputs received via the touch sensitive surface). After the end of a time period (e.g., 200 ms) at  426  where the control circuit ignores inputs received via the touch sensitive device, the control circuit may enable the touch sensitive device at  428  (e.g., respond to inputs received via the touch sensitive surface), and the control procedure  400  may exit. Thus, the touch sensitive device may be temporarily be disabled (i.e., the control circuit may ignore inputs receives via the touch sensitive device) after actuations of the actuator to turn the lighting load on and off in order to avoid turning the lighting load back on and/or otherwise adjusting the intensity level of the lighting load if the user&#39;s finger happens to sweep past the light bar  220  while moving away from the actuator. Further, the control circuit may adjust the length of the time period used at  426 , for example, using the advanced programming mode by the user and/or based on a learning algorithm and historical use patterns. 
       FIG.  19    is a flowchart of an example control procedure  500  that may be executed by a control circuit of a control device (e.g., a control circuit of the control device  200 , a control circuit of the control device  280 , a control circuit of the control device  1200 , any combination of the dimmer control circuit  314  or the user interface control circuit  354  of the control device  300 , and/or any combination of the control circuit  1310  or a control circuit of the touch sensitive device  1314  of the control device  1300 ) in response to a touch actuation along a touch sensitive surface of the control device. In examples where the control device includes multiple touch sensitive devices (e.g., a dual dimmer that includes two touch sensitive devices that each include a respective control circuit), the control procedure  500  may be performed by each of the touch sensitive devices of the control device. During the control procedure  500 , the control circuit may operate in an active touch mode while the touch sensitive surface is being actuated. For example, the control circuit may execute the control procedure  500  periodically at  510 . The control circuit may repeat the control procedure  500  for each of a plurality of regions of a capacitive touch circuit (e.g., the regions A-E of the capacitive touch circuit  352 ). 
     At  512 , the control circuit may first determine a change Δ CAP  in the count for the present capacitive touch pad of the capacitive touch circuit by determining the difference between the present count N CAP  and the baseline count N BL  for the present capacitive touch pad. When the control circuit is not operating in the active touch mode at  514 , the control circuit may execute a touch-in procedure at  516  to determine a number N TOUCH-IN  of times that the change Δ CAP  in the count for the present capacitive touch pad has exceeded a capacitance-change threshold TH CAP . When the number N TOUCH-IN  determined at  516  does not exceed a touch-in threshold TH TOUCH-IN  (e.g., such as two, three, four, five, six, seven, or eight) at  518 , the control procedure  500  may simply exit. When the number N TOUCH-IN  determined at  516  exceeds the touch-in threshold TH TOUCH-IN  at  518 , the control circuit may start a blanking period at  520  (e.g., a period of time where the control circuit ignores inputs received via the capacitive touch circuit, for example, as will be described in greater detail below with reference to  FIG.  13   ). For example, the user interface control circuit  354  may drive the touch actuation signal V ACT  high to indicate that the user interface control circuit  354  is operating in the active touch mode at  520 . Further, it should be appreciated that the control circuit may detect a touch actuation when the number N TOUCH-IN  determined at  516  exceeds the touch-in threshold TH TOUCH-IN . The blanking period may be, for example, 200 ms. The control circuit may then enter the active touch mode at  522 , and the control procedure  500  may exit. By ignoring inputs received via the capacitive touch circuit for the blanking period, the control circuit may, for example, avoid turning on the lighting load to an intensity level based on the position of a touch actuation on the actuation member (e.g., along the light bar  220 ) if the user&#39;s finger happens to sweep past the actuation member (e.g., the light bar  220 ) while actuating an upper portion of the actuation member or if the user&#39;s finger actuates the upper portion of the actuation member too close to the light bar. 
     When the control circuit is operating in the active touch mode at  514 , the control circuit may execute a touch-out procedure at  524  to determine a number N TOUCH-OUT  of times that the change Δ CAP  in the count for the present capacitive touch pad has not exceeded the capacitance-change threshold TH CAP . When the number N TOUCH-OUT  determined at  524  does not exceed a touch-out threshold TH TOUCH-OUT  at  526 , the control circuit may execute a slider position engine at  528 , for example, to determine and update the position of the actuation along front surface of the actuation member (e.g., along the light bar  200 ), before the control procedure  500  exits. When the number N TOUCH-OUT  determined at  524  exceeds the touch-out threshold TH TOUCH-OUT  at  526 , the control circuit may exit the active touch mode at  530 , and the control procedure  500  may exit. 
       FIG.  20    is a flowchart of an example control procedure  600  that may be executed by a control circuit of a control device (e.g., a control circuit of the control device  200 , a control circuit of the control device  280 , a control circuit of the control device  1200 , any combination of the dimmer control circuit  314  or the user interface control circuit  354  of the control device  300 , and/or any combination of the control circuit  1310  or a control circuit of the touch sensitive device  1314  of the control device  1300 ) in response to a touch actuation of along the front surface of an actuation member of the control device (e.g., a touch actuation of the touch sensitive surface of the actuation member  210  along the light bar  220 ). In examples where the control device includes multiple touch sensitive devices (e.g., a dual dimmer that includes two touch sensitive devices that each include a respective control circuit), the control procedure  600  may be performed by each of the touch sensitive devices of the control device. For example, the control circuit may execute the control procedure  600  at  610  at the beginning of a blanking period (e.g., the blanking period started at  520  of the control procedure  500 ). For example, the dimmer control circuit  314  may be configured to determine the beginning of the blanking period and execute the control procedure  600  in response to detecting that the touch actuation signal V ACT  has been driven high. In addition, the dimmer control circuit  314  may be configured to determine the beginning of the blanking period and execute the control procedure  600  in response to detecting a change in the output signal V OUT . While in the blanking period, the control circuit may determine if an on actuator or an off actuator has been actuated at  612 , determine if the active touch mode has been exited at  614 , and/or determine if the blanking period has expired at  616 . When the on actuator or the off actuator is actuated at  612  before the end of the blanking period, the control circuit may process the tactile actuation at  618  (e.g., by executing the control procedure  400  shown in  FIG.  18   ). 
     When the active touch mode is exited at  614  before the end of the blanking period, the control circuit may adjust the intensity level of the lighting load based on the position of the touch actuation at  620  (e.g., the position of the touch actuation along the light bar  220 ). For example, the dimmer control circuit  314  of the control device  300  may control the controllably conductive device  310  to adjust the intensity level of the lighting load based on the position of the touch actuation at  620 . In addition, the control circuit  1310  of the control device  1300  may transmit a message including control data for adjusting the intensity level of the lighting load based on the position of the touch actuation via the wireless communication circuit  1316  at  620 . Accordingly, the control circuit may be configured to adjust the intensity level of the lighting load based on the position of a touch actuation during the blanking period if the touch actuation is so quick as to cause the control device to exit the active touch mode before the end of the blanking period. That is, the control circuit may be configured to respond to a touch actuation if the touch actuation is less than the blanking time. 
     If the blanking period expires at  616  without the on or off actuators being actuated at  612  or the active touch mode being exited at  614 , the control circuit may adjust the intensity level of the lighting load based on the position of the touch actuation at  620 , and the control procedure  600  may exit. If the control circuit remains in the active touch mode at the end of the control procedure  600 , the control circuit may continue to adjust the intensity level of the lighting load based on the position of the touch actuation (e.g., as part of the slider position engine at  528  of the control procedure  500 ). 
       FIG.  21    is a flowchart of an example control procedure  700  that may be executed by a control circuit of a control device (e.g., a control circuit of the control device  200 , a control circuit of the control device  280 , a control circuit of the control device  1200 , any combination of the dimmer control circuit  314  or the user interface control circuit  354  of the control device  300 , and/or any combination of the control circuit  1310  or a control circuit of the touch sensitive device  1314  of the control device  1300 ) in response to a touch actuation along the front surface of an actuation member of the control device (e.g., a touch actuation of the touch sensitive surface of the actuation member  210  along the light bar  220 ). In examples where the control device includes multiple touch sensitive devices (e.g., a dual dimmer that includes two touch sensitive devices that each include a respective control circuit), the control procedure  700  may be performed by each of the touch sensitive devices of the control device. For example, the control circuit may execute the control procedure  700  periodically at  710  while the control circuit is operating in an active touch mode (e.g., while the touch sensitive surface is being actuated). In addition, the control procedure  700  may be executed at  528  of the control procedure  500  shown in  FIG.  19   . During the control procedure  700 , the control circuit may operate in an out-of-proximity mode when the control circuit has detected change of the position of the actuation of the touch sensitive surface (e.g., is operating in the active touch mode in response to the receiving capacitive touch pads  244 ), but the position is determined to be too far away from the light bar (e.g., in response to the proximity capacitive touch pad  245 ). 
     At  712 , the control circuit may first determine a change Δ CAP-PROX  in the count for the proximity capacitive touch pad of the capacitive touch circuit by determining the difference between the baseline count N BL-PROX  for the proximity capacitive touch pad from the present count N CAP-PROX  for the proximity capacitive touch pad. When the control circuit is not operating in an out-of-proximity mode at  714 , the control circuit may execute a proximity-out procedure at  716  to determine a number N PROX-OUT  of times that the change Δ CAP-PROX  in the count for the proximity capacitive touch pad has not exceeded a threshold. When the number N PROX-OUT  determined at  716  does not exceed an out-of-proximity threshold TH PROX-OUT  at  718 , the control circuit may execute a slider position engine at  720 , for example, to determine and update the position of the touch actuation along the actuation member (e.g., the light bar  200 ), before the control procedure  700  exits. When the number N PROX-OUT  determined at  716  exceeds the out-of-proximity threshold TH PROX-OUT  at  718 , the control circuit may enter the out-of-proximity mode at  722  and the control procedure  700  may exit. 
     When the control circuit is operating in the out-of-proximity mode at  714 , the control circuit may execute a proximity-in procedure at  724  to determine a number N PROX-IN  of times that the change Δ CAP-PROX  in the count for the proximity capacitive touch pad has exceeded an in-proximity threshold TH PROX-IN  (e.g., which may be the same threshold used in the proximity-out procedure at  716 ). When the number N PROX-IN  determined at  724  does not exceed the in-proximity threshold TH PROX-IN  at  726 , the control procedure  700  may simply exit. When the number N PROX-IN  determined at  724  exceeds the in-proximity threshold TH PROX-IN  at  726 , the control circuit may exit the out-of-proximity mode at  728 , before the control procedure  700  exits. 
       FIG.  22    is a flowchart of an example control procedure  800  that may be executed by a control circuit of a control device (e.g., a control circuit of the control device  200 , a control circuit of the control device  280 , a control circuit of the control device  1200 , any combination of the dimmer control circuit  314  or the user interface control circuit  354  of the control device  300 , and/or any combination of the control circuit  1310  or a control circuit of the touch sensitive device  1314  of the control device  1300 ) in response to a user input (e.g., a touch actuation, such as a press-and-hold actuation) applied to an area of an actuation member of the control device (e.g., the area  215  of the front surface  214  of the actuation member  210  shown in  FIG.  2   , or the central axis of the front surface  1235  of the actuation portion  1232 ) that does not cause the actuation member to move. For example, the control circuit may execute the control procedure  800  periodically at  810 . During the control procedure  800 , the control circuit may determine that a press-and-hold actuation (e.g., a user pressing and holding a finger against a front surface of the control device) has been applied to the area of the front surface of the actuation member of the control device. The press-and-hold actuation may be applied, for example, at a pivot location (e.g., over a pivot axis such as the pivot axis  222  shown in  FIG.  2   ) of the control device or a location furthest away from a mechanical switch (e.g., the tactile switches  262 ,  264 , or the tactile switches  1245   a ,  1245   b ) of the control device so that the press-and-hold does not accidentally trigger an unintended control function associated with the actuation switch. The control circuit may determine that a user input is a press-and-hold if the user input comprises a contact with the front surface that lasts more than a preconfigured time period (e.g., approximately 10 seconds). 
     In response to detecting the press-and-hold, the control circuit may enter an advanced programming mode at  814 , upon which the control circuit may flash one or more visual indicators to indicate that the control device is now operating in the advanced programming mode. While in the advanced programming mode, the control circuit may further determine, at  816 , a configuration or adjustment of an operating characteristic of the control device desired by the user. For instance, while in the advanced programming mode, the user may actuate the front surface of the control device along a light bar (e.g., the light bar  220 ) to indicate a desired value for a low-end trim of the control device and the control circuit may determine the desired value based on the position of the touch actuation. 
     At  818 , the control circuit may adjust the operating characteristic (e.g., the low-end trim) based on the user input (e.g., by storing the desired value in memory). Subsequently, at  820 , the control circuit may detect another press-and-hold applied at the pivot location indicating that the user wants to exit the advanced programming mode. In response, the control circuit may exit the procedure  800  at  822 . Additionally or alternatively, the control circuit may exit the procedure  800  at  822  if no user input has been detected for a period of time (e.g., which may be configurable) during the advanced programming mode. 
       FIG.  23    is a flowchart of an example control procedure  900  that may be executed by a control circuit of a control device (e.g., a control circuit of the control device  200 , a control circuit of the control device  280 , a control circuit of the control device  1200 , any combination of the dimmer control circuit  314  or the user interface control circuit  354  of the control device  300 , and/or any combination of the control circuit  1310  or a control circuit of the touch sensitive device  1314  of the control device  1300 ) in response to a tactile actuation of an actuator to turn a lighting load (e.g., the lighting load  304 ) on and/or off. The control device may comprise a touch sensitive device (e.g., the touch sensitive device  350 ) that is responsive to touch actuations along a front surface of the actuation member (e.g., along a touch sensitive surface of the actuation member  210  along the light bar  220 ). 
     When executing the control procedure  900 , the control device may ignore touch actuations received from the touch sensitive device(s) when the lighting load is off, and may respond to touch actuations received from the touch sensitive device(s) when the lighting load is on (e.g., only when the lighting load is on). For example, the control circuit may execute the control procedure  900  at  910  in response to a tactile actuation of the upper portion  216  or the lower portion  218  of the actuation member  210  that causes the actuation member  210  to pivot to actuate one of the tactile switches  262 ,  264 . If an on actuator was actuated at  912  (e.g., the upper portion  216  of the actuation member  210  was pressed to actuate the first tactile switch  262 ), the control circuit may determine if the lighting load is presently on at  914 . If so, the control procedure  900  may simply exit. If the lighting load is off at  914 , the control circuit may turn on the lighting load at  916  (e.g., by controlling the controllably conductive device  310  and/or by sending a message, such as a digital message, to a load control device to control the lighting load). For example, the dimmer control circuit  314  of the control device  300  may control the controllably conductive device  310  to turn on the lighting load at  916 . In addition, the control circuit  1310  of the control device  1300  may transmit a message including control data for turning on the lighting load the lighting load via the wireless communication circuit  1316  at  916 . 
     After turning the lighting load on at  916 , the control circuit may ignore inputs receives via the touch sensitive device at  918 . In some examples, the control circuit may disable the touch sensitive device at  918 . After the end of a blanking time period (e.g., approximately 200 ms) at  918  where the control circuit ignores inputs received via the touch sensitive device, the control circuit may enable the touch sensitive device at  920  (e.g., begin responding to inputs received via the touch sensitive surface), and the control procedure  900  may exit. Thus, the touch sensitive device may be disabled when the lighting load is off to avoid adjusting the intensity level of the lighting load if the user&#39;s finger happens to sweep past the touch sensitive surface of the actuation member (e.g., the light bar  220 ) while moving towards from the actuation member, and temporarily disabled (e.g., the control circuit may ignore inputs received via the touch sensitive device) after tactile actuations of the actuation member to turn the lighting load on in order to avoid adjusting the intensity level of the lighting load if the user&#39;s finger happens to sweep past the touch sensitive surface of the actuation member (e.g., the light bar  220 ) while moving away from the actuation member. Further, the length of the blanking time period used at  918  may be adjusted, for example, using the advanced programming mode by the user and/or based on a learning algorithm and historical use patterns. 
     If the on actuator was not actuated at  912 , but an off actuator was actuated at  922  (e.g., the lower portion  218  of the actuation member  210  was pressed to actuate the second tactile switch  264 ), the control circuit may determine if the lighting load is presently off at  924 . If so, the control procedure  900  may simply exit. If the lighting load is on at  924 , the control circuit may turn off the lighting load at  926  (e.g., by controlling the controllably conductive device  310  and/or by sending a message, such as a digital message, to a load control device to control the lighting load). For example, the dimmer control circuit  314  of the control device  300  may control the controllably conductive device  310  to turn off the lighting load at  926 . In addition, the control circuit  1310  of the control device  1300  may transmit a message including control data for turning off the lighting load the lighting load via the wireless communication circuit  1316  at  926 . At  928 , the control circuit may disable the capacitive touch circuit (e.g., begin to ignore inputs received via the touch sensitive device) before exiting the control procedure  900 . As such, when the lighting load is off, the control circuit may not respond to inputs received via the touch sensitive device (i.e., the capacitive touch circuit is disabled). In such examples, the control circuit may not response to (e.g., ignore) inputs received via the touch sensitive device for as long as the lighting load is off. However, in some examples, the control device may turn on the lighting load in response to touch actuations, such as special touch actuations like a long press-and-hold actuation (e.g., touch actuations that exceed a predetermined period of time), a double-tap touch actuations, etc.
