Abstract
An electrical switch system () for use with a motor vehicle transmission has a movable contact assembly () mounted on an insulative base member () in turn mounted on a detent lever (). The detent lever () is mounted on a manual shaft () for pivotal movement therewith while a housing is rotatably mounted on the manual shaft facing the detent lever. A plurality of side-by-side arcuate contact strips are insert molded in the housing wall with contact segments () exposed on a wall facing the movable contact assembly. The housing is maintained in one fixed angular position while movable contacts sweep across the contact segments upon pivotal motion of the manual shaft. A control gap is provided by ledges () formed in the housing with a lip () of the insulative base member () mounting the movable contact assembly received in the control gap to ensure that appropriate contact engagement between the movable contact assembly and control segments is maintained. In a modified embodiment an additional lip (') and corresponding housing ledge (′) is provided at an opposite side of the insulative base member.
