Title: SWITCH
Abstract:
Proposed is a switch that can cope with a conduction failure by using the switching operation of the switch. A switch 1 is provided with a center rod 5, a movable rod 12, upper-side fixed contact points 13, and lower-side fixed contact points 15. The movable rod 12 is provided with a movable contact point base. The movable contact point base is provided with an upper-side movable contact point plate 17, a lower-side movable contact point plate 19, and an auxiliary plate 21. At the time of closing as a result of movable contact points 21 and 23 coming into contact with the fixed contact points 13 and 15, respectively, the upper-side movable contact point plate 17 and the lower-side movable contact point plate 19 deform from curved surfaces that are concave upward and downward, respectively, into flat surfaces, thereby achieving a wiping action between the movable contact points and the fixed contact points and thus achieving the removal of insulating material etc. In addition, when the upper-side fixed contact points 13 and the upper-side movable contact points 21 are fused, forcible separation is possible as a result of the center rod 5 pressing down the movable rod 12.
