Abstract

A roller contact switch, designed for use in a housing having opposed ends of an interrupted electrical circuit, includes an axially extending, electrically non-conductive member. The non-conductive member includes an axially extending portion, which is substantially rigid against any transverse movement, partially received in the housing for sliding axial movement relative thereto, and an axially extending portion which is substantially resilient for a transverse movement of said flexible portion relative to said rigid portion and has a transversely biased free end defining a roller seat. The non-conductive member is biased for sliding axial movement towards one of the on and off positions. An electrically conductive rigid roller has a transversely extending cylindrical body supported by the roller seat for rotation within the housing relative thereto and for movement with the non-conductive member distal end between a first position, wherein the roller operatively connects opposed ends of an interrupted electrical circuit in the housing, and a second position wherein the roller is offset therefrom, the roller being biased by the roller seat in a transverse direction towards the opposed ends of the interrupted electrical circuit in the housing.
