Nordyne 632656 Dual Pressure Switch 0.7/0.2" WC

The Nordyne 632656 Dual Pressure Switch is an integral part of HVAC systems that control airflow. Operating based on the principle of dual pressures, it measures changes in pressure at two points within the system. This switch has two different pressures, 0.7" WC and 0.2" WC. The switch produces electrical signal when the pressure difference gets close or goes over the pre-determined values. Commonly found in furnaces, boilers and air handling units is the Nordyne 632656 with its dual-pressure capacity that allows for accurate control of both air flow rates and system functioning which enhancing effective heating and cooling efforts.
