Description
The Cleveland Controls DDP-109-318 pressure switch is used in HVAC systems to monitor air pressure and confirm proper air flow within the unit. It responds to pressure changes inside ducts or equipment and controls an electrical connection when set conditions are met. This component is typically placed in furnaces, air handlers, and ventilation sections where airflow verification is required for normal operation in HVAC systems. Its role is to ensure the system operates only under correct pressure conditions, assisting avoid issues related to restricted airflow or improper system cycling.
