Description
The Cleveland Controls NS2-1573-00 SPST/SPDT Fixed Differential Pressure Switch is an airflow and pressure sensing component used to monitor positive, negative, or differential air pressure in ducts and equipment systems. It operates within a low pressure range of 0.05 to 10 inches of water column and uses a diaphragm-based mechanism that triggers an internal snap switch when the set pressure threshold is reached. It is installed in air handlers, furnaces, and ventilation systems where airflow verification, filter monitoring, or safety interlocks are required.
