Lennox 49M50 Pressure Switch R-410A this air pressure sensing switchThe Lennox 49M50 is a high performance HVAC high pressure switch designed for critical system monitoring in residential and commercial cooling applications. This genuine OEM Lennox pressure switch functions as a primary safety control, specifically calibrated for a 640 psig cut out (C O) threshold. When refrigerant pressures exceed this safety limit, the switch breaks the electrical circuit to the compressor, preventing catastrophic component failure
