PURPOSE:To eliminate the need of a separate spring, facilitate assembling, and reduce the size by operation to move the free end part of a pushbutton, when it is pushed, slightly about a support point along a circle so as to operate a tact switch by a switch operating boss part protruding at the free end part. CONSTITUTION:If a pushbutton 1 is pushed, a pushbutton main body 2 moves its free end part slightly along a circle about a support point against the resiliency of a tongue part 26 having spring effect to operate a tact switch 5 by a switch operating boss part 24 protruding at the free end part. If pushing operation to the pushbutton 1 is released, the pushbutton main body 2 returns to an original position by the resiliency of the tongue part 26, releasing pressure to the tact switch 5 by the switch operating boss part 24. Assembling can thus be performed easily, and the need of a separate member of a spring, etc., is eliminated to reduced cost, and the structure itself can be more compact. |
