PURPOSE: To reduce the cost by composing a lamp terminal for feeding a light emission element to act as a plunger simultaneously.

CONSTITUTION: A lower end of a light emission element feeding lamp terminal 10 provided at a switch operating unit 1 is protruded under a lower end of a plunger 7 for putting on/off a switch main body 14, and a forward end of it is applied to a pushbutton 14a of the switch main body 14. The switch main body 14 is thus put on/off by the lamp terminal 10. If the switch operating unit 1 and a switch unit 2 are put part from each other, therefore, the switch main body 14 can be put on/off without forming the plunger 7 long. By connecting the lamp terminal 10 with a feed terminal 15 provided at the switch unit 2 electrically through a conductive spring 12, feeding a light emission element 8 can be achieved regardless of being on/off of the switch main body 14.
