1. A load control device for controlling an amount of power delivered from an AC power source to an electrical load, the load control device comprising:

  • a bidirectional 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 sensitive front surface adapted to be pressed;

    a touch sensitive device responsive to the touch sensitive front surface being pressed, the touch sensitive device having an output operatively coupled to the controller for providing a control signal representative of a position at which the touch sensitive front surface is pressed; 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 a first audible sound in response to the control signal of the touch sensitive device when the touch sensitive front surface is pressed, and to generate a second audible sound in response to the control signal when the touch sensitive front surface is released.
