Stud-mounted push-button switch for application on printed circuit board has contacts projecting from its mounting surface, providing pressure engagement with conductive areas on the board when the switch is mounted thereon, and also has a locating pin engageable with a hole in the board to assure and maintain axial orientation. The movable member has a plate slidably received in the switch housing, and a plunger extending from the plate into a mating recess in the housing. A coil spring surrounds the plunger and serves the dual functions of biasing the movable member to retracted position, and of retaining in position against the plate a bridging contact member adapted to complete an electrical circuit between the first-mentioned contacts when the movable member is advanced to operative position by pressure on the push-button.
