One-Touch Wipers

When the wiper stalk is pushed momentarily away from the driver, the wiper motor's low speed brush is grounded through the one-touch switch long enough for the wiper to move away from its PARK position. Once moved, it will continue to sweep because the wiper motor's low speed brush is now grounded through the wiper motor switch, the timing circuit, and the wiper switch. After one cycle, when the wiper returns to its PARK position, ground will be removed from the low speed brush and wiper operation will cease. Also, the wipers will continue to operate for as long as the wiper stalk is held in the one-touch position.
