GEN III Hemi AC Trinary switch.

A/C TRINARY SWITCH . has the ability of Closing contacts only when discharge pressure on Compressor reach’s a Pre Set amount. What does this mean to YOU? It allows you to replace our Standard Binary Switch and gain the ability of having your Electric Cooling Fan(s) to only come on when Discharge Pressure of A/C System reach’s a Preset Amount. This in turn makes your Electric Condenser/Coolant fan only come on when needed. So in other words, traveling down the road at 55-60 MPH, there generally is enough air passing through the condenser to not need your electric cooling fan to run unnecessarily.
