  • Multifunction stalk-mounted switch
    Patent number: 6624364
    Abstract: A multifunction stalk switch combines a pivoting lever and an internal rod which can be independently rotated and slid in an axial direction to control multiple functions, including separate control of wiper on/off/intermittent settings, an intermittent delay setting, and a washer spray function. A robust design is achieved by avoiding the need for any wiring or circuit boards within the lever arm itself and locating all electrically conductive components in the base. Relief notches in the lever prevent sliding contacts from moving away from the circuit board when the lever arm is pushed in a direction perpendicular to the desired pivot plane.
