Vehicular transmission sensor apparatus responsive to gear selection

A switch system for use with motor vehicle transmission apparatus having a detent lever with a plurality of detents on an outer edge surface thereof, each detent corresponding to a specific transmission gear selection, the detent lever being pivotable about an axis, a roller movable toward and away from the axis biased toward the outer edge surface, a switch housing mounted within the transmission adjacent the detent lever, the switch housing having an end pivotably mounted and an opposite and coupled to the roller so that the detent lever, when pivoted about the axis, moves relative to the switch housing, switch means having first and second electrical contacts movable relative to one another between contacts engaged and contacts disengaged positions, means to cause the contacts to move into a contacts engaged positioned at a selected angular position of the detent lever and means for electrically energizing the switch means and for outputting a signal therefrom corresponding to the respective contacts engaged and disengaged position.

A switch system for use with motor vehicle transmission apparatus having a pivotably mounted manual shaft and a detent lever with a plurality of detents on an outer edge surface thereof, each detent corresponding to a specific transmission gear selection, the detent lever being mounted on the shaft so that the angular orientation of the detent lever is fixed to that of the shaft, comprising a switch housing fixedly mounted adjacent the detent lever, the switch housing having a base, a switch arm mounted on the shaft so that the angular orientation of the switch arm is fixed to that of the shaft, the switch arm extending into the switch housing generally parallel to and spaced from the base, switch means mounted within the switch housing including at least one first electrical contact being mounted on one of the switch arm and the base, and at least one spring biased second electrical contact being mounted on the other of the switch arm and the base, one of the first and second electrical contacts being slidable between respective contacts engaged and contacts disengaged position with the other electrical contact as the manual shaft and switch arm are pivoted, and means for electrically energizing the switch and for outputting a signal therefrom corresponding to the respective contacts engaged and disengaged position.
