ABSTRACT:
An improved shock resistant auxiliary switch mechanism for a circuit breaker includes a common conductor having a conduction plate that is slidably translatable between electrically conductive contact with first and second conductors. The conduction plate is biased by a spring in a direction toward contact with the first conductor. An improved shock resistant circuit breaker including the improved auxiliary switch mechanism includes a crossbar that is operatively engageable with the conduction plate to releasably retain the conduction plate in a position in contact with the second conductor. When the circuit breaker is in an ON position, the conduction plate is operatively interposed between the crossbar and the bias of the spring.
