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.
