Auxiliary wiring and switching device of breaker mechanical characteristic tester

The invention relates to an auxiliary wiring and switching device of a breaker mechanical characteristic tester. The device comprises a fixed wiring module which is used for connecting a secondary circuit terminal of a circuit breaker to be detected; the wiring switching module is respectively connected with the fixed wiring module and the circuit breaker mechanical characteristic tester; the wiring switching module is used for controlling the circuit breaker mechanical characteristic tester to be switched among a plurality of test objects through switch switching so as to correspond to a plurality of test tasks respectively; the test objects comprise closing of the circuit breaker, first opening of the circuit breaker and second opening of the circuit breaker, and the test tasks comprise a direct current power supply on-off test, a direct current resistance test and a mechanical characteristic test. By adopting the device, single-phase or three-phase simultaneous action of the circuit breaker can be realized
