  • Light emitting diode assembly installed on the back of an electrical switch wall plate to indicate, in the dark, the location of the switch, or to indicate at any time an electrical circuit is carrying current
    Patent number: 4755913
    Abstract: A light emitting diode assembly is preliminarily installed on the back of an otherwise essentially standard switch wall plate of a standard electrical switch assembly, and thereafter connected optionally, either to indicate the location in the dark, of a turned off electrical switch assembly, by using a green light emiting diode connected across the terminals of the electrical switch assembly, or to indicate if the circuit is energized to carry current, upon the turning on of an electrical switch assembly, by using a red light emitting diode connected in the load circuit. A resistor and a direct current diode are utilized to modify the voltage and current for the light emitting diode. A plastic material is used to hold in place a substantial portion of the light emitting diode assembly on the back of the switch wall plate, while portions of the light emitting diode extend through a hole in the switch wall plate, to be observed throughout the space to be lighted.
