磁開閉器の復帰装置。 A main contact provided in the power path, an electromagnetic drive mechanism that operates by energization from the power path each time an operation switch is operated, and an electromagnetic drive mechanism that opens the main contact each time the electromagnetic drive mechanism operates. It is connected to an electromagnetic switch that is provided with a contact switching mechanism that alternately drives from close to open and from close to open, and opens and closes together with the main contact provided in a path parallel to the operation switch. an auxiliary contact and a break contact, an actuator that holds the break contact open when the power path is connected by the main contact and closes the break contact when the power is cut off; A delay circuit is provided that delays opening of the break contact until the main contact is opened by the electromagnetic drive mechanism when the power is cut off when the main contact is in a closed state and the power is turned on again. Return device for electromagnetic switch.
