Claims

[Scope of utility model registration request]

(1) A loss bar that has a through hole in the side surface and is movable in the axial direction, a movable contact that passes through the through hole and is supported on the cross bar by a spring, and both ends of the movable contact that protrude laterally from the cross bar. In the electric circuit switching device, the shape of the movable contact is set to 2 at both ends of the movable contact, and a pair of fixed contacts are disposed so as to face each other.
The movable contact has a chevron shape with a ridgeline that overlaps the line connecting the centers of the four movable contacts, and the cross-sectional shape of the movable contact in the direction perpendicular to the line connecting the centers is asymmetrical with respect to the line connecting the centers. An electrical circuit switching device characterized by:

(2) In the device set forth in claim (1) for utility model registration,
An electric circuit switching device characterized in that the cross-sectional shape of a movable contact is made asymmetrical by providing a groove at a position offset from its center line.
