Claims

[Scope of utility model registration request]

a coil, a fixed core disposed within the coil,
A movable core that is attracted to the fixed core by the excitation of the coil, a contact section that opens and closes when the movable core attracts and opens the fixed core, and a contact section that slides into both end faces of the movable core to attract and open the movable core. In a switch consisting of a mounting base for accommodating and arranging the coil, fixed iron core, movable iron core, etc., and guided by the inner wall surface, the movable iron core, which has a large number of laminated thin iron core plates, is pressed from both sides in the stacking direction. The movable iron core is characterized by comprising a fixed plate that clamps and fixes the movable iron core, and a sliding piece that extends from the end of the fixed plate and is located between the inner wall surface of the mounting base and the end surface of the movable iron core. Switch electromagnetic device.
