Summary:The use of a Gray code ganged wiper switch and an electronic circuit controlling the washer-pump motor and wiper motor allow the use of a minimal number of wires in the overall interval wiper system than found in conventional systems. Circuit redundancy and Gray coding method provides several added reliability features at a low manufacturing cost. The system further provides a resistorless control of the several power output functions of the system.
