Circuit breaker auxiliary switch conversion counting device

The utility model relates to the technical field of circuit breakers, and discloses a circuit breaker auxiliary switch conversion counting device which comprises a main shaft crank arm, a first connecting rod and a counter. When the circuit breaker is switched from an opening state to a closing state, the main shaft crank arm rotates and drives the first connecting rod to rotate along the first direction, so that the first connecting rod drives the rotating end of the counter to rotate. In the process that the circuit breaker is switched from the closing state to the opening state again, the main shaft crank arm rotates and drives the first connecting rod to rotate in the direction opposite to the first direction, the first connecting rod drives the rotating end of the counter to continuously rotate, at the moment, the circuit breaker passes through the opening-closing-opening process, one is added to the number displayed by the counter, and the number displayed by the counter is calculated. And one is added
