Abstract

A multi-function control switch for electrically operating devices, such as a lighting system, is disclosed. The multi-function control switch includes a rocker-type actuating arm for actuating a plurality of momentary switches. When actuated, the momentary switches send signals to an electronic operating module which houses a control logic circuit. The control logic circuit receives input keying sequences from the user, and interprets the input to determines whether the input keying sequence is associated with any of the command logic elements stored in its memory, and whether the system may validly switch from the current operating function to the new operating function. If the transition is valid, the control logic circuit signals the electronic operating module to execute the command logic element associated with the new operating function.
