摘要：
Disclosed is a switching mechanism for a motor protection circuit breaker capable of reducing a force required to adjust a handle, and capable of enhancing the reliability to break a circuit. The switching mechanism for a motor protection circuit breaker comprises a push link having an outer circumferential curved surface of a varying cam profile, so as to enhance a function to break the circuit by pressing movable contact plates.
