ABSTRACT:
An electric switch used with motor vehicle transmissions is shown in which the switch arm (22') is mounted on a manual shaft (30) to be movable therewith and is received in a housing (44) which has an end freely rotatable about the manual shaft and an opposite end coupled to the detent lever roller (16). Ingress of debris into the housing is prevented, in one embodiment, by annular sealing elements (54, 56) formed of resilient material and having a curved surface extending in a radial direction disposed around the manual shaft (30) on either side of the switch arm between the switch arm and the housing. In a second embodiment a single annular sealing element (56) is used on one side of the switch arm (22") and the switch arm (22") on its opposite side and the base (12") of the housing are formed with matching curved surfaces (27, 29). In another embodiment the switch arm (64) is fixedly mounted on the detent lever (42) through a depending leg (66) with housing (82) having an end rotatably mounted around the leg (66) with the opposite end of the housing coupled to the detent lever roller (16).
