Claims

[Scope of utility model registration request]

A reversible first part made of an elastic conductive material is disposed within the case.
A movable contact is disposed below the first movable contact, a recoilable second movable contact made of an elastic conductive material is disposed, and a first movable contact in contact with the first movable contact is disposed in the case. A fixed contact is provided, and a second fixed contact is in contact with the second movable contact, and a center contact is provided in which the center of the second movable contact is brought into contact with and separated from the first movable contact. Due to the reversal operation, the first movable contact contacts the second movable contact to connect the first fixed contact and the second fixed contact, and the second movable contact due to the reversal operation of the first movable contact. In the switch device, the second movable contact contacts the center contact due to the reversal operation of the movable contact, thereby connecting the first and second fixed contacts and the center contact. 2 fixed contacts are arranged at one location in opposite directions centering on the center contact, and portions of the first and second movable contacts that abut the bottom surface of the case and the first or second fixed contact. A switch device characterized in that a wear-preventing tongue piece is provided on each of the sides.
