ABSTRACT:
A system, device and method to allow communications between switches in an electrical circuit containing three-way and four-way switches. The system, device and method allow any switch in an electrical circuit using conventional wiring for three-way and four-way switches to indicate when voltage is being supplied to the electrical load device in the electrical circuit; if a dimmer is present in the electrical circuit, to indicate the dim level of the load device in the electrical circuit and to command to dim level from any switch; and if a timer is present, to allow any switch to provide a warning indication prior to the timer shutting off the load device, and to allow any switch to reset the timer, preventing the shutoff.
