Shop AC pressure switches for heavy-duty truck air conditioning systems at All Pro Truck Parts. Pressure switches protect the AC system by shutting down the compressor when system pressure goes too high or too low — a failed switch can allow the compressor to run in unsafe conditions, leading to compressor damage or a system blowout. We carry high-pressure, low-pressure, and combination pressure switches for the most common Class 6 through Class 8 truck platforms.
Visit our help center if you need help finding the right AC pressure switch for your truck.
