Alternate action push-push switch

摘要

An alternate action push-push switch is disclosed, having a housing with a dielectric bar portion; a plurality of conductive terminals; a plurality of conductive spring contactors having an inclined segment in proximity to the dielectric bar portion and a contact segment in proximity to the terminal contact portion; at least one push member slideably disposed at least partially within the housing; an alternate action switch mechanism having a closed loop cam slot, a cam follower, and a resilient spring disposed between the housing and the push member, to provide unidirectional travel of the cam follower in the cam slot as the push member is alternately biased between first and second operating positions. More than one push member may be used to supply multiple switching configurations. A protrusion on a first push member may be adapted to actuate an adjoining second push member, while allowing the second push member to be operated independently of the first push member. This switch provides a snap action, sliding contact and release which is particularly useful for D.C. switching.
