ABSTRACT:
Shaft holes 12 and 22 are formed on each pivot portion of a switch case 10 having an unfolded fan shaped concave body 11. A stationary contact base 20 covers the concave body, and a corresponding end portion of a shaft holder 40 are fitted into the respective holes to rotate freely. In addition, positioning through-holes 18 and 27 are formed at each corresponding portion of the switch case 10 and the stationary contact base 20. Either the switch case 10 side or the stationary contact base side 20 is set on an assembly jig 80 toward these shaft holes 12 and 22 and the positioning holes 17 and 27. As a result, the lever 72 can be engaged from either side of the switch case 10 or the stationary contact base 20.
