Two-position electrical switch assembly

Abstract

A two-position electrical switch assembly is disclosed for mounting in an aperture of a metal panel. The housing for the switch assembly is constructed of an electrically non-conducting body having a head portion and a shank portion. The head portion is integrally formed with the shank portion such that the shank portion extends transversely away from a panel contacting surface of the head portion. A central opening is formed through the head portion and extends coaxially with an axial opening formed longitudinally through the shank portion. The shank portion includes means for resiliently mounting the switch assembly housing in the apertured middle panel where the resilient mounting means includes a first electrical conducting member, a pair of spring-biased electrical conducting fingers, and a second electrical conducting member. The pair of spring-biased electrical conducting fingers are disposed longitudinally in the axial bore with their free ends normally biased together. One of the pair of conducting fingers is connected to the first electrical conducting member and the other pair of conducting fingers is connected to a second electrical conducting member which has an electrical terminal portion extending outwardly of the body portion. A plunger element of an electrically non-conducting material is inserted through the central opening to cause the pair of spring-biased fingers to separate and thereby open the electrical conducting path between the first and second conducting members.
