Claims

[Scope of utility model registration request]

A movable contact is provided at both ends and is slidably and loosely inserted and held in a window hole of a crossbar, and a fixed contact is placed opposite to the movable contact, and the movable contact is movable and fixed by sliding of the crossbar. In a contact device for a switch that connects and disconnects both contacts to control the opening and closing of an electric circuit, the contact surfaces of a pair of fixed contacts are formed as inclined surfaces in the same direction that are inclined in the longitudinal direction of the movable contact.
