Brake Switch (Cruise Control): Description and Operation
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.
