Abstract
A switch including a housing and an actuator configured to move axially within the housing. The actuator includes a guide wing on a first side and a cam wing on a second side, wherein the cam wing has a cam surface on one face. The switch also includes respective first and second contact terminals partially extending from the housing, as well as a movable contact element retained within the housing proximate the contact terminals. The movable contact element includes a fixed branch, a first elastically deformable conductive blade, and a second elastically deformable conductive blade. The cam surface on the actuator is configured to cooperate with the first elastically deformable conductive blade to deform or relax the first elastically deformable conductive blade so as to selectively contact the first contact terminal dependent upon the axial position of the cam wing within the housing.
