ABSTRACT:
A switch operating mechanism associated with a motor driven hydrostatic system operative in forward or reverse directions with respect to a neutral inoperative state, for rendering a motor starting circuit operative only when the hydrostatic system is in its neutral state. An axially movable switch operating shaft has a notch therein which receives a detent on the control stem of the switch, only when the shaft is in a position generally centrally between opposite limits of its axial movement, to close the switch. A centering spring urges the shaft toward its centrally disposed position.
