Abstract
A vehicular transmission sensor having an electrical output responsive to gear selection is shown having a plurality of sealed electrical switches mounted within the transmission housing. In a first embodiment a cam plate is disposed on a face of the detent lever and is movable therewith relative to the switches. The switches are each provided with a follower which moves between switch contacts engaged and switch contacts disengaged positions in dependence on the angular position of the cam plate. In a second embodiment a switch arm mounting a plurality of first switch contacts is movable with the detent lever into and out of engagement with respective second switch contacts mounted in a sealed stationary housing.
