  • Contact mechanism for temperature switch using thermal expansion member
    Patent number: 4368449
    Abstract: A contact mechanism for a temperature switch using a thermally expandable member wherein a plate making a circular arc motion is provided at a tip of a piston which is moved by the thermal expansion member, and a coil spring is mounted between a middle of a movable member having a fulcrum in an almost center of the plate and a stationary end of a terminal. The movable member is reversibly mounted. The plate is moved by the motion of the piston. When a point of power of the movable member is shifted, the movable contact is shifted instantly to the stationary contact side, and the movable contact slides on the stationary contact by the motion of the piston. The coil spring doubles as the return spring.
