Description
The Cleveland Controls NS2-1119-00 DPDT Pressure Switch is a differential air pressure control component used to monitor airflow conditions within heating, and cooling equipment. It is applied in system configurations where accurate pressure sensing is required to verify proper venting and safe operational conditions. In HVAC systems this switch, rated at 0.55″ WC, responds to changes in pressure by opening or closing electrical circuits, supporting controlled system sequencing and safety operation. Installed within the pressure sensing circuit, it helps ensure airflow verification, stable operation and coordinated interaction between combustion control and system safety components.
