Abstract
In this breaker device, a pair of stationary electrodes ( ) are arranged while the protruding wall ( ) is interposed between them and the U-shaped movable electrode ( ) is engaged with them so as to close an electric circuit. The protective protruding section ( ) is arranged at an upper end of the stationary electrode ( ), and the protrusions ( ) are provided on both sides of the protective protruding section ( ). When the movable electrode ( ) is engaged, it is elastically expanded and deformed when it comes into contact with the protrusion ( ). Even in a case in which the protrusion ( ) is scraped away by the friction caused between the protrusion ( )and the movable electrode ( ), since the protrusion ( ) is located at a position shifted from the stationary electrode ( ), the scraped powder never gets into between the movable electrode ( ) and the stationary electrode (
