Claims

[Scope of utility model registration request]

(1) In a device in which a movable core is operated by excitation and demagnetization of an electromagnet to open and close contacts, a fixed core is provided at a position where the movable core approaches and separates depending on the motion, and this fixed core A switch characterized in that it is equipped with a shock absorber installed on either one of the movable iron cores opposite to the movable iron core, and that cushions the impact when the contacts are closed. .

(2) The switch according to claim 1, wherein the buffer has a structure having a damper function.
