Nordyne 632452R Pressure Switch ensuring hole-pattern alignment and simplifiedThe Nordyne 632452R Pressure Switch is a critical OEM safety component for gas fired furnaces and HVAC systems. As a Single Pole Single Throw (SPST) air pressure sensing switch, it is calibrated to a precise 1. 00" WC (Water Column) set point. This switch serves as the direct 632390 replacement, ensuring proper airflow verification for the combustion process. When the inducer motor or draft booster creates the required negative pressure, the switch
