Claims

[Scope of utility model registration request]

A cylindrical electromagnetic coil is installed inside the yoke, and a fixed core is attached to one end of the yoke. A plunger-shaped movable core is supported so as to be able to move freely, and this movable core is attracted to the fixed core by the energization of the electromagnetic coil, and is moved back outward by a compression spring when the electromagnetic coil is deenergized. A contact part is attached to the outer end of the fixed iron core, and a fixed contact is attached to the inside of this contact part frame, and it passes through the center part of the fixed iron core and is movable in the axial direction. A movable contact is attached to the tip of the supported support rod and corresponds to the fixed contact at a distance, and when the movable iron core is attracted to the fixed iron core, the support rod or pusher is moved and the movable iron is attached to the fixed iron core. An electromagnetic switch device, characterized in that the movable iron core portion is provided with a ventilation hole that communicates from the inner end side to the outer end side.
