Abstract
A multifunction switch assembly includes a handle having an actuator mounted at an inner end. The actuator and handle are pivotally mounted in a housing. First and second return springs mounted in the housing bias the actuator towards the neutral position from the left and right turn positions, respectively. The first return spring preferably imparts a higher force against the actuator than the second return spring, in order to counter the effects of gravity acting upon the handle. The first and second return spring preferably both impart opposite forces on the actuator when in the neutral position in order to eliminate play.
