Claims

[Scope of utility model registration request]

The crossbar includes a movable contact provided on the movable contact disposed surfaces at both ends, and a movable contact that is slidably and loosely inserted and held in a window hole of the crossbar, and a fixed contact disposed opposite to the movable contact. In a switch contact device in which both the movable and fixed contacts are connected and separated by sliding to control the opening and closing of an electric circuit, the movable contact mounting surfaces at both ends of the movable contact are both relative to the longitudinal direction of the movable contact. 1. A contact device for a switch, characterized in that the movable contacts are twisted in the same direction, and the movable contacts are opposed to the fixed contacts in an oblique direction.
