Abstract

In a circuit breaker switching mechanism in which when a latch is released by setting a handle lever at the "on" position, a toggle link unit made up of upper and lower links with a center pin therebetween is elastically reversed thereby to trip the circuit breaker, an interfering stopper is held in contact with the periphery of the upper link to limit the operation of the latter thereby to cause the center pin to move straightly when tripped, whereby the period of time required for opening the circuit breaker is minimized.
