Abstract: A dimmer switch system electrically connected between a power source and a load includes a primary housing including a primary switch actuatable by a user, a processor structured to change a state of the dimmer switch based on actuation of either the primary switch or the secondary switch, and a secondary switch isolation circuit. The dimmer switch system also includes a secondary housing including a secondary switch actuatable by the user and being electrically connected to the power source. The secondary switch isolation circuit is electrically connected between the secondary switch and the processor, the secondary switch isolation circuit including a transistor electrically coupled between the power source and the processor and being structured to provide impedance between the power source and the processor. The secondary switch isolation circuit is structured to provide a signal to the processor based on a state of the secondary switch.
