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. It helps prevent equipment operation when airflow is insufficient, supports reliable combustion, improves system safety, and protects heating and ventilation components from potential damage.

For an efficient and reliable HVAC system, the Cleveland Controls Air Proving Switch is a great choice for optimal system performance.
