Abstract
In the breaker device, a pair of stationary electrodes are arranged on the front and the rear side of the protruding wall , that is, the pair of stationary electrodes are collected at one place. Therefore, the pair of stationary electrodes have a space round both the stationary electrodes in common. Accordingly, the size of the breaker device can be reduced. Further, when the radius of curvature of the continuity section connecting the pinching pieces is made large, concentration of stress in the movable electrode can be relieved. Therefore, the pinching forces of both the pinching pieces can be increased. Accordingly, it is possible to ensure a sufficiently high contact pressure between the movable electrode and the stationary electrodes
