Abstract
A multifunctional switch stalk includes controls for both the front and rear wash and wiper functions. The multifunction switch stalk includes a handle having a shaft extending to an outer end of the handle. A rear control ring is rotatable on the shaft to actuate the rear wiper functions. The rear control ring may also actuate a rear window wash in either of two extreme rotational positions. A spring return returns the rear control ring from each rear window wash position upon release of the control ring by the operator. A control knob is mounted on an outer end of the shaft and is rotatable to selectively actuate the front windshield wiper functions. An axially compressible wash push button is mounted on the outer end of the control knob to selectively actuate a front windshield wash function.
