ABSTRACT:
A switch having a carriage with a pair of substantially opposite sides and a contact surface of conductive parts facing one of the sides and a reaction surface facing the other of the sides in spaced relation therewith, and wherein the carriage is movable relative to and substantially parallel with the contact surface and the reaction surface, and has an improved contact mechanism carried by the carriage. The carriage has plural openings extending therethrough perpendicular to the contact surface and the reaction surface. The contact mechanism comprises a respective plurality of plungers, springs, conductive contact members and a common conductive retainer. Each contact member is slidably disposed in a respective one of the carriage openings and is adapted for engagement with the contact surface. Each spring is interposed in compression between a respective contact member and a respective plunger. Each plunger is in contact with the reaction surface to urge the respective contact member into engagement with the contact surface. Each plunger includes a head portion and a pin depending from the head portion. Each contact member is hollow and open at its end facing the reaction surface and includes a shoulder in the hollow which faces the open end. The retainer is structured to allow limited resilient deflection of one end relative to the other in a direction axially of the carriage openings, but to be substantially rigid to forces applied in a transverse direction.
