Supco SMR440 M/R High Pressure Switch 440 PSI Cut-Out

The Supco SMR440 M/R High Pressure Switch 440 PSI Cut-Out contains a control component designed to check the refrigerant pressure in the HVAC systems and therefore stops the compressor operation. It operates by detecting the changes in pressure by utilizing an inner diaphragm and closing electrical contacts to interrupt the circuit. It is fitted in air conditioning and heat pump systems with the pressure line. This switch not only improves the protection but also minimizes the chances, and it also enables the stable operation.
