ABSTRACT:
An indicator light for a switch to show when a remote load is energized is provided for installations where no neutral wire is available at the switch box. A circuit including a gas discharge indicator lamp, a diode-resistor charging circuit and a capacitor across the lamp is connected between the load side of the switch and the grounding conductor in the switch housing. Current through the circuit is sufficiently small to create no hazard.
