Patent ID: 8212165

Claim:
A switch comprising a blade-type moving contact, which is rotatably and pivotally supported and reciprocates such that a free end of the blade-type moving contact draws a rotation locus, and a fixed contact that has conduction members with which the moving contact comes into contact, wherein the fixed contact comprises a pair of the conduction members that are arranged opposedly and substantially in parallel to each other such that tip ends of the conduction members are oriented toward an opening, a pedestal member that tiltably supports bases of the conduction members, a pressurizing member that biases the conduction members in a direction in which the tip ends of the conduction members approach each other, and a shielding member that covers peripheries of at least the conduction members and the pressurizing member and shields them from an outside electric field, the pressurizing member is arranged on an outer side of the opposed conduction members, and the shielding member engages with the tip ends of the conduction members, overcomes a biasing force of the pressurizing member, and maintains an opening width between the tip ends of the conduction members at a predetermined width.
