ABSTRACT:
A multi-function circuit controller provides auxiliary control functions for an existing single-pole, single-throw toggle switch by counting the number of changes of state of the switch that occur within predesignated delay periods from one state change to the next. An encoder responsive to a sequencer counter develops control functions such as dimming and timing functions which attenuate the power delivered to the load and regulate the on-off time of the load. The invention may be used in conjunction with a household lighting circuit to provide these functions for an existing wall-mounted switch, thereby providing dimmer and programmable timing for the lighting normally controlled by the switch.
