Abstract
An electrically conductive annular elastic contactor is trapped in a cavity in a housing defined by a bottom wall and left and right side walls. A movable operator cammingly engages the contactor, compressively deforming it until an overcenter position is passed, after which the contactor snaps against the opposite side wall to make and/or break contact with stationary contacts mounted on at least one of the walls.The contactor acts both as the movable contact for engaging stationary contacts and as snap action biasing means for effecting switching operations. Due to the resilient deformation of the contactor, there is afforded a torsional shearing of contact welds.
