Abstract: A circuit breaker assembly incorporating a light emitting diode as an indicator when an overload condition is present and the circuit has been blown and further wherein the assembly includes an integral, internally placed load in the form of a capacitance sufficient to energize the light emitting diode when the load normally present in the circuit has been removed. The capacitance is connected in series with the light emitting diode as well as an external ground contact for providing the ground return for energizing the light emitting diode.

Abstract: An improved circuit breaker with overload condition illuminated indicator having a secondary switch coupled to the movement inherent in conventional circuit breaker levers. The improved circuit breaker is self-powered with batteries thereby insulating itself from possible power failures.

Abstract: A magnetically actuated illuminating warning device for conventional circuit breakers of the type that have a switch assembly with three possible positions for its switch lever. A battery powered illuminating device is mounted in the vicinity of the breaker and the illuminating circuit is interrupted by a magnetically actuated switch that is closed when a permanent magnet mounted on the switch lever comes within a predetermined distance. The position of the magnetic switch is selected so that it is actuated or closed when the switch lever is in the overload position.
