Patent ID: 7608948

Claim:
A load control device for controlling the amount of power delivered to an electrical load from an AC power source, the load control device comprising: a semiconductor switch operable to be coupled in series electrical connection between the source and the load, the semiconductor switch having a control input for controlling the semiconductor switch between a non-conductive state and a conductive state; a controller operatively coupled to the control input of the semiconductor switch for controlling the semiconductor switch between the non-conductive state and the conductive state; a touch screen actuator having a touch sensitive front surface responsive to a plurality of point actuations, each characterized by a position and a force, the touch screen actuator having an output operatively coupled to the controller for providing a control signal representative of the position of the point actuation; a visual display responsive to the controller; and an audible sound generator responsive to the controller; wherein the controller is operable to cause the visual display to illuminate and the audible sound generator to generate an audible sound in response to the control signal of the touch screen actuator.
