Circuit breaker anti-bounce auxiliary contact

Disclosed is a circuit breaker anti-bounce auxiliary contact. The circuit breaker anti-bounce auxiliary contact is characterized by comprising an auxiliary contact bracket; a micro switch group is fixedly mounted in the auxiliary contact bracket; a lever is mounted in the auxiliary contact bracket and can turn; one end of the lever is in linkage with the micro switch group while the other end is in linkage with a cam lever; the cam lever is mounted in the auxiliary contact bracket and can turn; one end of the cam lever is in linkage with the lever while the other end is in linkage with a mechanical rotary arm; and one end of a reset spring is mounted on the auxiliary contact bracket and the other end is mounted on the cam lever. The circuit breaker anti-bounce auxiliary contact is additionally provided with multi-stage lever transmission mechanisms, so that the mechanical rotary arm does not trigger the auxiliary micro switch in the bounce process, thereby avoiding the technical shortcoming of inaccurate swit
