Nordyne 632520R SPST Pressure Switch -0.80" WC

The Nordyne 632520R SPST Pressure Switch is an essential part of HVAC systems, its main function being to measure the pressure of air in the systems. Located at a pressure of -0.80 WC, this single pole, single-throw switch guarantees the proper and safe working of the system. When the pressure drops below the desired level, the switch turns on or off the system to begin or halt operation to avoid harm from low pressure. This pressure switch is widely applied in different heating and cooling equipment such as gas furnaces and air conditioning units, where the pressure should be controlled.
