Claims

[Claims for Utility Model Registration] (1) A pair of rising pieces are provided on the common terminal disposed on the switch base, a movable contact piece is supported on the rising piece so as to be able to pivot up and down, and the rising piece is sandwiched between the rising pieces. By installing a tension coil spring between the movable contact piece and an actuating piece provided at a position facing the movable contact piece, the actuating piece or the tension coil spring itself is pressed by an external force to release the tension coil. In the switch mechanism that reverses the movable contact piece via a spring and switches the fixed contact piece that comes into contact with the movable contact piece, a pair of convex portions are provided on either the side surface of the rising piece or the operating piece on the other side. A switch mechanism characterized in that a concave portion is provided to engage with the convex portion, and the operating piece is engaged with the rising piece by a circular boss having a concave and convex relationship. (2) The switch mechanism according to claim (1) of the utility model registration, further characterized in that the operating piece is formed of an elastic plate and bent in a U-shape. (3) The switch mechanism according to claim (1) or (2) of the utility model registration, further characterized in that a concave-convex engaging portion is provided on the outside of the pair of rising pieces.
