BINARY and TRINARY TM Switches R12/R134a Compatible Binary Switches perform two functions; A. Prevents compressor operation if system has refrigerant loss or ambient temp. drops too low. B. Prevents compressor operation if high side pressure rises too high. Automatically resets when pressure drops to normal. Trinary II Switches are found on systems equipped with radiator shutters and/or electric or air fan clutches. They perform three functions: A. Prevents compressor operation if system has refrigerant loss, or ambient temp. drops too low. B. Prevents compressor operation if high side pressure rises too high. Automatically resets when pressure drops to normal. C. Overrides shutter/fan control to keep head pressure within normal range.

SOLENOID VALVES AN AIR OPERATED SOLENOID VALVE is an electronic control used to operate (engage & disengage) the air actuated engine fan clutch and/or radiator shutters on the vehicle. It can be plumbed to operate in either a normally open (N.O.) or normally closed (N.C.) position, depending upon the type of fan on the vehicle, and the specific inlet port used on the solenoid.
