Abstract

Provided is a push switch which has less variations in load characteristic and operation life among products and the deformation of a press member is kept small. The push switch includes a case including a recess, first and second fixed contact points arranged on a bottom surface defining the recess, a bulging dome-shaped movable member placed on the bottom surface so that an end portion thereof is in contact with the first fixed contact point, the movable member electrically connecting the first and second fixed contact points when the dome configuration is inverted by pressing, a protective sheet covering the recess, and a press member clamped between the protective sheet and the movable member, pressing the movable member and including a top surface which is in contact with the protective sheet, and a flat bottom surface which is smaller than the top surface and is in contact with the movable member.
