Signal feedback mechanism for vacuum circuit breaker and vacuum circuit breaker

The invention is suitable for the technical field of vacuum circuit breakers, and provides a signal feedback mechanism for a vacuum circuit breaker and the vacuum circuit breaker, and the signal feedback mechanism comprises a mechanism accommodation box, a driving mechanism and a feedback mechanism. The driving mechanism comprises a transmission box, the transmission box is vertically and fixedly connected to one side face of the mechanism containing box, one side face of the transmission box is fixedly connected with a protection box, and an inner cavity of the protection box is fixedly connected with a motor. According to the signal feedback mechanism for the vacuum circuit breaker and the vacuum circuit breaker, the lifting plate drives the second elastic block to be in contact with the second microswitch to monitor the switching-on state, and when the rack plate drives the lifting plate to descend, the first elastic block is in contact with the first microswitch to monitor the switching-off state; the sit
