PURPOSE:To surely detect that a circuit breaker is moved to a breaking position, by providing switches in an operating position and a breaking position in a switchboard case and opening/closing the switches by the interlocking pin of the circuit breaker. CONSTITUTION:A microswitch 13 is provided in the operating position A of a microswitch fitting metal 15 in a circuit breaker lockup metal 10. Another microswitch 14 is provided in the breaking position B of the fitting metal 15 in the metal 10. When the interlocking pin 11 is operated, the microswitches 13, 14 are also operated. Thereby, the operating position and the breaking position of the circuit breaker can be surely detected. |
