The Nordyne 632487R Pressure Switch (-0.90" Water Column, SPST) is a safety control device designed to monitor airflow and draft pressure in HVAC heating systems. It senses the negative pressure created by the inducer motor and closes its electrical contacts when the required vacuum level is reached, allowing the furnace ignition cycle to proceed. If proper pressure is not detected, the switch interrupts the circuit to prevent unsafe operation. Commonly used in gas furnaces and packaged heating units, it helps ensure proper venting, reliable combustion, improved system safety, and consistent heating performance.
For an efficient and reliable HVAC system, the Nordyne Pressure Switch Water Column SPST -0.90 Inch is a great choice for optimal system performance.
