Description
The Cleveland Controls NS2-1366-03 SPDT Air Pressure Snap-Acting Sensing Switch W/0.25″ Barbed Fitting is a pressure-actuated control component used to monitor airflow condition in heating, and cooling equipment. It is applied in system configurations where accurate detection of differential air pressure is required for safe operation. In HVAC systems, this switch responds to pressure changes by rapidly opening or closing electrical contacts to verify air flow, venting, or inducer performance. Installed within the pressure sensing circuit, it supports safety interlocks, system startup sequencing, and communication between air flow monitoring and control components.
