Description
The Cleveland Controls AFS-405-112 Air Pressure Sensing Switch is a pressure-operated control module used to detect changes in air pressure within connected circuits. With an adjustable operating range from 0.05″ to 12″ WC, it responds to variations in airflow conditions and activates electrical switching based on preset pressure levels. It is commonly applied in duct systems, air handling sections, and other HVAC systems where airflow confirmation or pressure-based signaling is required. The switch connects to sensing points within the airflow path to transmit pressure changes into control circuit responses during system operation.
