ていることを特徴とするスイツチ。 The base end of an elastic contact piece, which has a movable contact at the tip that corresponds to a fixed contact provided on the wiring board, is fixed to the wiring board, and is a metal that expands and contracts thermally due to temperature changes caused by energization. One end of the wire is
The metal wire is connected to the contact piece near the point where the contact piece and the wiring board are fixed, and the metal wire is pulled out from the connection point with the contact piece to the tip side of the contact piece. The other end is fixed to the engaging piece provided on the wiring board side, and further, the length is longer than the length from the swinging fulcrum of the contact piece, which swings as the metal wire expands and contracts due to heat, to the connecting point. A switch characterized in that the length from the swinging fulcrum to the movable contact is longer.
