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 equipped with a pin mounting leg that has a pin through hole that passes through the neck of the movable core, and a crossbar that is connected to the movable core support by a core connecting plate spring. In a switch that attracts a movable core by applying a voltage to open and close contacts, the pin through hole of the movable core support is formed to be somewhat larger than the outer diameter of the movable core pin, so that the neck of the movable core and the movable A switch characterized in that a cushioning rubber is interposed between a central flat plate part of an iron core support.
