Claims (1)

[Scope of utility model registration request] An electromagnet that is housed in a housing and generates mechanical displacement according to the energized state, a movable frame that is biased by a return spring in response to the mechanical displacement of the electromagnet, and a movable contact that is attached to the movable frame. In an electromagnetic contactor consisting of a movable contact plate that is attached to the housing, and a fixed contact plate that is fixed to a housing and has a fixed contact that faces the movable contact, a slide is provided in the housing with an operating lever that projects from the movable frame. A latch means is provided that protrudes from the hole and latches the movable frame when the movable frame is slid by the operating lever a predetermined distance in a direction in which both contacts come into contact against the return spring, and the latch means for the movable frame is provided. A latch release means is provided to appropriately release the latch from outside the housing, and when the movable frame is slid by a predetermined distance slightly beyond the mechanical displacement range caused by the electromagnet using the operation lever, the latch means is activated and both contacts are brought into contact. An electromagnetic contactor characterized in that both contacts are opened by maintaining the latch and operating a latch release means.
