ABSTRACT:
A substantially fan-shaped stationary contact base is provided at its pivot of the fan with a shaft hole and at its outer periphery with mounting bosses, each having a through bore. The mounting boss is formed in the middle of the outer periphery of a circular arc to have an enlarged area in the circumferential direction where there is provided an elongated positioning slot which is extended in the radial direction of the shaft hole. A shaft holder supported by a switch case is inserted into the shaft hole and a positioning projection provided on the side of the switch case is then inserted into the elongated positioning slot so that the stationary contact base and the switch case can be assembled together. Since the circumferential direction of the stationary contact base is predetermined by the positioning projection, the stationary contact base is secured, while adjusting its position in the radial direction to the side of the switch case by screws each passed through the corresponding through bore for improving the positioning accuracy of the shaft holder.
