PROBLEM TO BE SOLVED: To provide a switch allowing a switch lever to be mounted and removed simply, easily, and quickly, decreasing the risk of switch lever being damaged at mounting and removal as much as practicable, and allowing mass- production of short switch levers at a low cost. SOLUTION: A switch is structured so that a switch lever 2 is rotatably coupled with a rotation hole 5 in a circuit board 1 furnished with a stationary contact 4, which is slid to a movable contact 3 and rotated so that switching is generated by these contacts 3 and 4. The switch lever 2 is equipped with a rotary shaft 8 to be inserted into the hole 5 in such a way as capable of rotating, a drive part 9 coupled with one end of the rotary shaft 8, and a protruding stopper 7 coupled with the other end of the rotary shaft 8. The board 1 is provided with a passage opening 6 which is in communication with the hole 5 and admits passage of the stopper 7. The switch is arranged so that the lever 2 is rotated in a position where the stopper 7 is not guided to the opening 6 and the switching is generated by the two contacts 3 and 4. |
