Description
The Nordyne 1023972R N/O Pressure Switch responds to airflow level variation through a two-pole normally open switching configuration that changes electrical contact status when preset sludge levels are reached. The switch operates in HVAC systems with calibrated operating points of 0.85 and 0.30 pressure settings, allowing connected circuits to react according to airflow and combustion conditions. It is positioned near inducer and ventilation pathways where pressurization balance influences operational sequencing. Its 2-pole contact arrangement maintains a regulated circuit, allows for monitored airflow checking, and contributes to optimal thermal and ventilation outputs.
