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 spring holder is shaped like a chevron with a ridgeline that overlaps the line connecting the centers of the two movable contacts, and is positioned in contact with the upper surface of the movable contact, making the left and right weights of the member unbalanced with respect to the center line. electrical circuit switchgear.

(2) In the device set forth in claim (1) for utility model registration,
An electric circuit switching device characterized in that a hole is formed in a spring receiving member at a position eccentric to a line connecting the centers of movable contacts so that the left and right weights with respect to the center line are unbalanced.
