The Cleveland Controls NS2-1166-01 Air Proving Switch is an HVAC safety control designed to monitor airflow and verify that adequate air pressure is present during equipment operation. It operates by sensing differential air pressure; when the required pressure level is reached, the internal contacts change state and provide an electrical signal to the control circuit. This switch is commonly used in furnaces, unit heaters, rooftop HVAC systems, air-handling equipment, and commercial heating appliances.
