Summary:PURPOSE:To ensure safety and avoid a remote control impossible state by providing a slide plate interlocked with the opening and closing of a door and slid by a slide plate operating metal fitting to control a safety switch and a lock lever. CONSTITUTION:A slide plate 25 is slid by a slide plate operating metal fitting 23 fixed to a door, when the door is opened and closed, to open and close a manual handle insert hole 39 and also operate a safety switch for turning ON/OFF the power supply of an electric control device. A lock lever 17 is operated by a lock lever operating plate taking two stable positions to the ON and OFF/trip of a circuit breaker 1, and engaged with and disengaged from a lock metal fitting 44 fixed to the door. An interlock device with the door is integrated to a mounting frame 35, whereby it is not required to provide a safety switch for cutting the operating power source when the door is opened, and the space can be saved. Since the careless manual operation when the door is opened is prohibited by the double safety structure, safety can be ensured, and a remote control impossible state can be avoided.
