Cleveland Controls NS2-1063-00 Air Pressure Switch

The Cleveland Controls NS2-1063-00 Air Pressure Switch is a safety-monitoring part that identifies airflow or differential pressure in HVAC systems. It works by detecting variations in air pressure in ducts or heat exchangers, and switching an internal switch when preset pressure limits are exceeded. The switch is installed in the pressure tubing network of the system with the correct orientation and is connected to control circuits to allow or break electrical connections. It is to verify that there is sufficient draft or blower functionality and guard against unsafe furnace, boiler, and air handler HVAC equipment.
