US 11,445,585 B2 · Non-neutral-based, illuminated electrical load controls

Abstract

An illuminated electrical load control is provided for controlling electrical power to a light-emitting diode (LED) lighting load. The load control includes a wall-box mounted housing, and an electrical switch assembly disposed at least partially within the housing. The switch assembly includes an actuator coupled to transition the switch assembly between an ON state, where AC current flows to the LED lighting load, and an OFF state, where current is interrupted from flowing to the LED lighting load. Further, the load control includes an illumination assembly with an indicator light to illuminate, at least in part, the load control when the switch assembly is in OFF state, and a current-limiting circuit connected across terminals of the switch assembly, and configured to limit leakage current through to the LED lighting load to below an activation current of the LED lighting load when the switch assembly is in the OFF state.
