Abstract

A pair of closed contacts having moving contacts (27A), (27B) and fixed contacts (25A), (26A), (25B), (26B) are provided in a mutual locking device (3) and excitation circuits of two electromagnetic contactors which are inversely connected to respective closed contacts to effect electrical interlocking. The moving contacts (27A), (27B) are held by respective levers (36A), (36B) interlocked with driven members (5A), (5B) to be driven by corresponding moving contact supports of the electromagnetic contactors and opened when the electromagnetic contactor closes. Thus, electrical interlocking may be simultaneously effected using a mutual locking device for mechanically preventing two electromagnetic contactors reversibly connected from simultaneously closing.
