Binary A/C Pressure Switch K301-370-1 – Alltrux ATX922-1231

The Alltrux ATX922-1231 Binary A/C Pressure Switch replaces OEM K301-370-1 and is designed as a service replacement for heavy-duty truck HVAC and air conditioning systems. This M10 binary pressure switch monitors refrigerant system pressure and helps protect the compressor and related components by cycling the system on or off when pressure thresholds are reached, supporting reliable climate control operation in fleet and vocational environments. Binary A/C pressure switches play a critical role in HVAC system protection by preventing compressor operation under unsafe low or high pressure conditions. As original switches wear electrically, develop internal faults, or lose calibration, HVAC performance and compressor reliability can be affected. Replacing worn binary switches helps restore proper pressure monitoring, improve system safety, and reduce unplanned HVAC service events.
