Abstract
A switching mechanism in a circuit breaker having a latch being locked from moving when the circuit breaker is in a normal "on" state, a toggle link having a striking part being coupled to the latch and elastically urged with an elastic force by a switching spring at times when the circuit breaker is in the normal state and released from said urge at times when the circuit breaker is tripped or changed from the normal state to a tripped "off" state, and a stopper disposed adjacent the striking part of the toggle link in that when the circuit breaker is tripped, the latch is released to cause the striking part of the toggle link strike the stopper intermediate in the tripping action so that the time required for completing the tripping of the circuit is reduced.
