Claims

[Scope of utility model registration request]

A fixed core attached to a mounting base, an operating coil attached to the fixed core, a movable core that is attracted to the fixed core, and a movable core pin that is placed over the neck formed by providing a step at the top of the movable core. It consists of a movable core support that passes through the neck of the movable core and is connected to the movable core, and a crossbar that is connected to the movable core support by a core connecting leaf spring, and a voltage is applied to the operating coil from a power source. In the switch which sucks the movable core by using the movable core and opens and closes the contacts, the movable core support is formed into a U-shaped cross section, and a notch is provided at the center upper edge of each opposing end portion for inserting a core connecting plate spring. A rectangular ring-shaped guide having a section is disposed outside so as to surround the movable core support, and is also installed on the upper step of the movable core, and the movable core pin is placed on both sides of the guide together with the movable core and the movable core support. A switch characterized by being penetrated.
