Abstract
A pushbutton switch is formed by: an insulating body molded of an insulating material and into a box-like shape having an opening at on end, a pair of fixed contact pieces to be electrically connected to and disconnected from each other being embedded in the inner bottom surface of the box-shaped insulating body; a rotary actuator rotatably supported at one end in the insulating body and formed at the other end as a unitary structure with a push button which projects out of the insulating body; and a plate spring formed by a retaining contact piece engaged at one end with the free end of the rotary actuator and a movable contact piece sliding at one end on the inner bottom surface and coupled at the other end with the retaining contact piece in such a manner as to define a V-letter shape between them, the plate spring resiliently biasing by the reaction force from the inner bottom surface of the insulating body the push button in the direction in which it projects out through the opening of the insulating body.
