The Cleveland Controls NS2-0556-00 Air Flow Switch is an essential part used in HVAC systems to control the airflow in different equipment. This switch operates based on airflow, and its sensing element is designed to detect presence or absence of airflow. The switch is triggered to shut and create an electrical circuit to indicate the proper functioning of the system. In case of restricted or lack of airflow, the switch opens to produce an alarm or stop the equipment from functioning or getting damaged. This ensures the better performance and energy use as well as protects against risks that come with low airflow to the systems including overheating and or system failure.
