AI Technical Summary
Technical Problem
In the prior art, the breaker operating mechanism opens and bounces, resulting in unreliable bounces of the auxiliary switch contacts, causing unstable electrical indication signals, and the auxiliary switch is susceptible to burning, affecting its conversion and electrical life.
Method used
An auxiliary switch is designed, including a micro switch, a trigger and a push-up member. Through the coordination of the give way slot and the projection, the contacts are ensured to switch stably between the disconnection position and the trigger position, and avoid unnecessary bounce.
Benefits of technology
It effectively ensures that the electrical indication signal of the auxiliary switch is stable and reliable, extends the service life and reduces the risk of burning.

Abstract
The utility model discloses an auxiliary switch and a circuit breaker, belonging to the technical field of low-voltage electrical appliances, the auxiliary switch comprises a base, a microswitch, a trigger piece and a pushing piece, the microswitch is arranged on the base, the microswitch comprises a switch body and a contact, the trigger piece is arranged on the base in a sliding manner along a first direction, and the pushing piece is arranged on the base. The trigger piece comprises a lug boss arranged opposite to the contact in the first direction; the abutting piece is arranged on the side, opposite to the contact, of the triggering piece in the first direction, a receding groove is formed in the side, facing the triggering piece, of the abutting piece, and the groove bottom width of the receding groove in the second direction is larger than the width of the protruding part in the second direction. The abutting piece slides in the second direction so that the protruding part can be arranged in the receding groove or be separated from the receding groove, and therefore the microswitch can be disconnected and triggered. According to the auxiliary switch provided by the utility model, stable triggering and breaking of the microswitch are effectively ensured, stable and reliable electrical indication signals of the auxiliary switch are effectively ensured, and the service life of the auxiliary switch is effectively prolonged.
