ABSTRACT:
A switch comprises a plunger, a retainer, a pair of terminals and an electrically-conducting wiper contact having a curved or bent middle portion defining two oppositely directed legs on either side of the middle portion. The retainer cooperates with the plunger to carry the wiper contact as the plunger moves between a normal and an actuated position. The terminals have facing contact surfaces for biased engagement with the portions of the legs exposed by the plunger and retainer to form an electrical path between the terminals when the plunger is in the actuated position. The plunger and the retainer are coupled together by arms which project from either the plunger or the retainer. The wiper contact is secured between the plunger and retainer without the need for forming a central loop in the wiper contact for engagement by the plunger.
