National Comfort Products 14265029 High Pressure Switch is a protective control device that is applied in HVAC refrigerant systems. It serves to measure the pressure of the system and stops its work in case of excess pressure, which helps the compressor and other parts to avoid damage. This switch is factory calibrated to fit in compatible National Comfort Products units and is normally mounted on the high side of the refrigerant circuit, wired in directly to the safety control system of the unit.
