Combination Cruise/Stop Light Switch


A separately mounted vacuum release valve is used with this combination switch. When the brake pedal is depressed, the switch resets the cruise function to a non-cruise condition and illuminates the brake lights. Two sets of electrical contacts are used in the switch: one to operate the stop lights, and the other to operate the cruise release function.
