Abstract

A circuit breaker is shown having movable contacts carried by an operating member which moves between a circuit breaker contacts closed position and a circuit breaker contacts open position. An auxiliary switch has electrically conductive, flexible contact members adapted to engage an electrically conductive bridging shaft element carried by the operating member when the operating member is in one of its two positions to provide means for indicating the status of the circuit breaker.
