Abstract

A multimode switch includes a line voltage switch, coupled to a line voltage and a device; a switch controller that directs the line voltage switch to provide line voltage to, and subsequently remove line voltage from, the device, and that receives first identifying information and a functional group designation for the device, and that controls the device according to the first identifying information and the functional group designation; and a ground leakage power supply, coupled to an AC hot line and to an earth ground, that generates a regulated voltage to power the switch controller without requiring connection to an AC neutral line, while limiting ground leakage current to the earth ground to a prescribed leakage value.
