ABSTRACT:
A load control device for controlling the 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; a controller operatively coupled to the control input of the semiconductor switch for controlling the amount of power delivered to the load; an actuator operatively coupled to the controller such that the controller is operable to determine a desired amount of power to be delivered to the load in response to actuations of the actuator; and a visual display responsive to the controller; wherein the controller is operable to illuminate the visual display to a first intensity upon actuation of the actuator and to subsequently illuminate the visual display to a second intensity less than the first intensity after a predetermined amount of time has elapsed since the actuation of the actuator.
