閉器。 A permanent magnet that is rotatable around a fulcrum between both magnetic poles, a magnetic body placed near one pole tip of the permanent magnet, and a superconducting magnet placed between this magnetic body and the pole tip of the permanent magnet. A magnetic shield body made of material, a movable contact provided at a predetermined portion of the permanent magnet, and a fixed contact that comes into contact with and separates from the movable contact according to the rotational position of the permanent magnet, the magnetic shield body The temperature is characterized in that the permanent magnet and the magnetic body are repelled or attracted to each other by bringing the permanent magnet and the magnetic material into two states of a high temperature below or above a critical temperature, thereby causing the contact points to connect and separate. switch.
