     This is a continuation of International Application PCT/US14/65777, with an international filing date of Nov. 14, 2014, entitled “PIVOTING ELECTRICAL SWITCH”, which claims the benefit of priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 62/046,624, entitled “PIVOTING ELECTRICAL SWITCH,” filed Sep. 5, 2014, the contents of which are incorporated herein by reference in their entirety for all purposes. 
    
    
     FIELD 
     The described embodiments relate generally to electrical switches. More particularly, the present embodiments relate to electrical switches that can be toggled through a pivoting motion or include a welded cover for improving structural integrity of the electrical switch. 
     BACKGROUND 
     Many mobile devices include electrical switches configured in spaces of the mobiles devices that can prove to be unsuitable for frequent toggling of the electrical switches. In some cases, the force required to toggle an electrical switch can cause certain portions of the electrical switch to bend or warp in a way that causes the electrical switch to malfunction or degrade over time. This issue can be more problematic when the electrical switch is configured to receive a toggling force that has a trajectory different than the trajectory required to toggle the electrical switch. In such scenarios, the mechanisms used to translate the toggling force into the correct toggling motion for the electrical switch can prove to be unreliable over the lifetime of the electrical switch.

     DETAILED DESCRIPTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims. 
     The following disclosure relates to device components for mobile devices. Specifically, the disclosure relates to a pivoting switch useful for providing an electronic switch at a curved surface of a mobile device. Typically, a switch that is provided along the curvature of a mobile device housing can be positioned against a curved surface inside the mobile device housing. However, in many cases the switch can rotate or become offset from an intended course for toggling the switch. This can lead to degradation of the switching function after frequently toggling the switch over time. In order to prevent such degradation, a pivoting switch is provided herein that incorporates one or more pins that are secured within a bracket allowing the pivoting switch to rotate about an axis defined by the pins and the bracket. The pivoting switch is configured to provide a user with a sensation that a rotating switch is being toggled, when actually the pivoting switch is toggling a linear switch. The linear switch can be secured to the bracket in a way that allows the movement of the pivoting switch to toggle the linear switch. To accomplish this, a switch knob of the linear switch can be disposed within a pocket or cavity of the pivoting switch allowing the pocket to force the switch knob to move with the pivoting switch. Some amount of clearance or free space can be provided between the pocket and switch knob in order to reduce the amount of friction occurring at the switch knob. However, in some embodiments, a rotating switch is used in place of the linear switch to allow a switch knob of the rotating switch to be more securely grasped by the pocket and be toggled through substantially the same motion as the rotating switch. Moreover, in some embodiments, the rotating switch and pivoting switch can be a single integral switch where no pocket is necessary because the portion that would be the pivoting switch is a single integral piece that includes a knob of a rotating switch. 
     Additionally, the following disclosure relates to a welded switch cover for protecting against wear caused by toggling of a switch over time. An electrical switch can typically include a switch cover that secures a switch knob and other components of the switch in place. Occasionally, the switch cover can be secured using a protruding lip that is configured to receive a latch that keeps the switch cover secured to the switch. However, over time the switch cover can become loosened by frequent toggling of the switch knob and weakening of the lip and latch. This can lead to malfunctioning of the switch and potentially loss of functionality of the mobile device in which the switch is operable. In order to provide a more secure switch cover, a welded switch cover is provided herein in order to more securely attach the switch cover to a body of the switch. The cover can be welded onto the switch body using any suitable form of welding not limited to heat staking, cold staking, insert molding, contact welding, laser welding, or some other type of bonding. The welded switch cover can cover can abut a surface of the switch and include an aperture for allowing the switch knob to protrude through and be toggled. The welded switch cover can be made from stainless steel, copper, or any suitable material that can be welded to an electrical component. A welded arm can be provided at one or more edges of the welded switch cover adjacent to the switch knob. The welded arm can include one or more apertures for receiving a bonding material to be welded to the switch body and the welded arm. In this way, a solid bond between the switch body and the arm can be provided in order to better confine the motion of the switch knob and prevent degradation of the switch as a result of frequent toggling. In some embodiments, the welded switch cover can provide protection from electrostatic discharge. For example, when the switch includes metal features configured inside of a plastic mobile device housing, the welded switch cover can ground the metal features of the switch to a common ground of the mobile device to prevent buildup of static electricity. 
     These and other embodiments are discussed below with reference to  FIGS. 1-9 . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these Figures is for explanatory purposes only and should not be construed as limiting. 
       FIG. 1  illustrates a perspective view of a computing device  100 . The computing device  100  can include a device housing  104  having a curved perimeter and a switch  102  protruding from an aperture in the device housing  104 . The switch  102  can be configured in a variety of ways in order to provide the user with a simple means of toggling a function of the computing device  100 . However, depending on how the switch  102  is configured, toggling the switch  102  can be detrimental to the operation of the computing device  100  over time. For example, if the switch  102  is configured to slide against one or more curved surfaces within the device housing  104 , such a configuration can lead to racking within the switch  102 . Racking can occur when a portion of the switch rotates in a direction away from a toggling direction of the switch thereby causing stress to the switch  102  that can lead to a malfunctioning of the switch  102 . 
       FIG. 2A  illustrates a cross-sectional view  200  of a typical sliding button  204 . Specifically,  FIG. 2A  illustrates how the sliding button  204  can move along a surface of the device housing  104  in order to toggle the button  206 . When the sliding button  204  is forced to move in the sliding direction  202 , the sliding button  204  forces a knob  208  of the button  206  to move linearly in substantially the same direction as the sliding direction  202 .  FIG. 2B  illustrates a cross-sectional view  210  of the sliding button  204  moving in a sliding direction in order to toggle the button  206  in an opposite direction compared to  FIG. 2A . Toggling the button  206  in this manner can lead to stress on the button  206  when the sliding button  204  moves in a direction that is away from a direction for toggling the button  206 . Additionally, the knob  208  can be bent away from different sides of the button  206  leading to the malfunction of certain electrical connections within the button  206 . In order to cure the deficiencies of  FIGS. 2A and 2B , the pivoting switch described herein is provided. 
       FIGS. 3A and 3B  illustrate cross-sectional views  300  and  310  of the pivot switch  308  configured at a curved surface of the device housing  104 . In order to detail the mechanisms by which the pivot switch  308  operates, the button  206  was not illustrated in  FIGS. 3A and 3B . The pivot switch  308  operates by a sliding motion that can be performed in a pivot direction  302  and a pivot direction  312 . The pivot switch  308  operates according to a rotational movement defined by the combination of a bracket  304  and a pin  306 . The pin  306  can be secured within an aperture or cavity of the bracket  304  in a way that allows the pin  306  to act as an axle for the bracket  304 . The pin  306  can be configured to rotate a total of at least 90 degrees in some embodiments, in order to accommodate a button that can use such a depth of motion. The pivot switch  308  can be configured to abut the device housing  104  or be offset slightly by free space or some other material in order to reduce friction between the device housing  104  and the pivot switch  308 . A switch cavity  314  can be provided in the pivot switch  308  in order to receive a knob  208  of a button  206 . The switch cavity  314  can be configured in a variety of sizes and shapes in order to accommodate different knob  208  sizes. Additionally, as illustrated in  FIGS. 3A and 3B , the switch cavity  314  can be configured to face the pin  306  and/or the bracket  304  at least at some or all points during a pivot motion that toggles the button  206 . In some embodiments, the pivot switch  308  can include one or more pins  306  that are secured to one or more brackets  304 . The pins  306  can be any suitable shape in order to securely grasp or be grasped by the bracket  304 . For example, the pins  306  can be ring or hook shaped in order to grasp an axle that can extend through one or more brackets  304 , allowing the pivot switch  308  to rotate about the axle. Moreover, in some embodiments, the pivot switch  308  can include a flexible portion that allows toggling of a button  206  through bending and flexing of the flexible portion. 
       FIGS. 4A and 4B  illustrate cross sectional views  400  and  402  of the pivot switch  308  toggling a button  206  that is proximate to a curved surface of the device housing  104 . Specifically,  FIG. 4A  illustrates the knob  208  being moved in a linear direction similar to the pivot direction  302  in order to toggle the button  206 .  FIG. 4B  illustrates the knob  208  being moved in a linear direction similar to pivot direction  312  in order to toggle the button  206  to a position different than that of  FIG. 4A . The knob  208  can be at least partially enveloped by the switch cavity  314  in order to force the knob  208  to move with the pivot switch  308 . Although the bracket  304  and button  206  are illustrated as floating features in the figures, it should be noted that the bracket  304  and button  206  can be secured to any suitable surface in the device housing  104 . The bracket  304 , pin  306 , and pivot switch  308  can be made from any suitable material for providing a mechanism to toggle the button  206 . Each of the bracket  304  and the button  206  can be secured to a surface in the device housing  104  in a way that causes a portion of the pivot switch  308  to at least partially protrude from an aperture in the device housing  104 . Additionally, the sides of the pivot switch  308  that are adjacent to the partially protruding portion can be configured to abut a curved interior surface of the device housing  104 . Moreover, the button  206  can be configured to abut at least a portion of a surface of the bracket  304  in order to provide an anchor for the button  206  when the knob  208  is being shifted by the pivot switch  308 . In some embodiments, the button  206  is secured to a different surface than a surface of the bracket  304 . In this way, the leverage applied to the knob  208  by the pivot switch  308  can be adjusted by modifying the proximity of the pin  306  to both the knob  208  and an end of the pivot switch  308  opposing the pin  306 . 
     Although the pivot switch  308  is illustrated as a separate entity than the button  206  and knob  208 , in some embodiments, the knob  208  is integral to the pivot switch  308 . In this way, the knob  208  can be caused to move in a curved or non-linear sliding direction with the pivot switch  308 . This can be especially useful when the button  206  is a rotating button that is toggled when the knob  208  is moved through a curved or non-linear sliding direction. In some embodiments, the button  206  can be a 2-way, 3-way, or N-way switch (where N is any suitable whole number) in order to provide a variety of modes that the button  206  can be toggle between. In some embodiments, the button  206  can be configured to act as a power switch, audio-off switch, vibrate-on switch, or any other suitable switch that can toggle between various device modes. 
       FIGS. 5A-5C  illustrate views of the pivot switch  308  according to some embodiments discussed herein. Specifically,  FIG. 5A  illustrates a perspective view  502  of the pivot switch  308  having a pin  306  abutting the bracket  304  at a distal end of the pivot switch  308 .  FIG. 5B  illustrates a perspective view  504  that sets forth a side of the pivot switch  308  opposing a side of the pivot switch  308  illustrates in  FIG. 5A . The pivot switch  308  can include one or more pins  306  that can abut one or more portions of the bracket  304  in order to secure the pivot switch  308  between an inner surface of the device housing  104  and the bracket  304 .  FIG. 5C  illustrates a cross-sectional view  506  of the pivot switch  308  and an axis of rotation  508  of the pivot switch  308 . The axis of rotation  508  can be defined by one or more pins  306  and be parallel to a surface of the button  206 . When the pivot switch  308  is rotated about the pins  306 , the switch cavity  314  transfers a force to the knob  208  that moves the knob  208  in a linear direction relative to the direction of rotation of the pivot switch  308 . For example, the linear direction of the knob  208  can depend on whether the pivot switch  308  is rotating clockwise or counter clockwise about the axis of rotation  508 . In some embodiments, instead of a switch cavity  314 , the pivot switch  308  can include a lip that protrudes toward the button  206  and can push the knob  208  in different linear directions when the pivot switch  308  is rotated about the axis of rotation  508 . 
       FIG. 6  illustrates a perspective view  600  of a switch  602  that is secured to a switch body  610  by a cover  604 . The cover  604  is secured to the switch body  610  using a latch  608 . The latch  608  is configured to grip the switch body  610  on multiple sides of the switch body  610  and be held in place by a lip  606 . The switch body  610  can include one or more lips  606  that protrude from one or more surfaces of the switch body  610  in order to provide a locking mechanism for the cover  604  and latch  608 . However, because of the movement of the switch  602 , the lip  606  can degrade over time allowing the latch  608  to become loose. As a result, the switch  602  can be displaced from the switch body  610  thereby permitting the switch  602  to move in a non-linear path that the switch  602  was not originally designed to move in. This can lead to malfunctions of the switch  602  and loss of some functionality in the mobile device that the switch  602  is operable within. 
       FIG. 7  illustrates a perspective view  700  of a switch  602  having a welded cover  702  that is welded, according to some embodiments discussed herein. The welded cover  702  can extend over a surface of the switch body  610  and at least partially reside on a surface of the switch  602  in order to sustain the switch  602  against the switch body  610 . The welded cover  702  can include an aperture for the switch  602  to move and toggle according to a force applied by a user of a mobile device in which the switch can be operable. The welded cover  702  can include one or more welded arms  704  that extend in a direction that is substantially perpendicular to a surface of the switch body  610  on which the switch  602  resides. Additionally, in some embodiments, the welded arms  704  can extend in a direction that is parallel or non-parallel to the surface of the switch body  610  on which the switch  602  resides. In yet other embodiments, the welded arm  704  can extend at least partially across a surface of the switch body  610  that opposes the surface on which the switch  602  resides. The welded arm  704  can include one or more cover welds  706  that bind the welded arm  704  and welded cover  702  to the switch body  610 . The welded cover  702  can be made from stainless steel or any suitable material for receiving a weld. The welded cover  702  can include multiple welded arms  704  that can extend onto multiple surfaces of the switch body  610  to further secure the welded cover  702  to the switch body  610 . In some embodiments, the cover welds  706  are included at multiple surfaces of the switch body  610 , and at least one or more of the surfaces can include multiple adjacent cover welds  706 . In other embodiments, a single cover weld  706  can be used to bind the welded arm  704  to a surface of the switch body  610 . The welded arm  704  can be welded to the switch body  610  using any suitable method for welding a switch cover to a switch. For example, in some embodiments, one or more welding methods such as heat staking, cold staking, laser welding, deposition, insert molding, or any other suitable binding method can be used to secure the welded arm  704  to the switch body  610 . Although the cover welds  706  are illustrated as circular in  FIG. 7 , it should be noted that the cover welds  706  can be any suitable shape, such as elliptical or polygonal, in order to provide a secure weld for the welded cover  702 . 
       FIG. 8  illustrates a perspective view  800  of the welded cover  702  having an electrical contact  802 . The electrical contact  802  can provide a conductive pathway to one or more components included in the switch body  610 . The electrical contact  802  can be included in a portion of the welded cover  702  that extends parallel or non-parallel to a surface of the switch body  610  that supports the switch  602 . In some embodiments, the electrical contact  802  can replace one of the cover welds  706  in order to provide an electrical contact at the welded arm  704 . In this way, an electrical contact  802  can be provided at multiple surfaces of the switch body  610  while the cover welds  706  can concurrently bind the welded cover  702  to the switch body  610 . In some embodiments, the electrical contact  802  can be used to provide electrostatic discharge protection for the switch  602  and connect to a common ground of the mobile device in which the switch can be operable. Moreover, in some embodiments the electrical contact  802  can be provided on a surface of the switch body  610  that opposes the surface on which the switch  602  resides in order to allow the switch to be exclusively surface mounted onto an electrical connection or circuit. 
       FIG. 9  illustrates a method  900  for welding a switch cover to a switch. The method  900  can be performed by any suitable machine, controller, computer, or apparatus suitable for performing welding functions. The method  900  can include a step  902  of manufacturing a switch cover having one or more arm features each including one or more apertures. The apertures can define the placement of the welds, such as the cover welds illustrated in  FIGS. 7 and 8 . The method  900  can further include a step  904  of disposing the one or more arm features onto one or more surfaces of a switch. Thereafter, at step  906 , the one or more arm features are welded at the one or more apertures to one or more surfaces of the switch. In this way, the welds can contemporaneously abut the surfaces of the switch through an aperture of the each of the arm features. Using the method  900 , a more secure cover can be provided for switches having a propensity to malfunction as a result of the switch cover separating from a surface of the switch.
