The Cleveland Controls NS2-0220-00 Pressure Switch of SPDT is meant to monitor and act upon fluctuating air pressure in HVAC systems. Maintaining a standard pressure of 1.25 inches of water column this switch functions as a pressure sensor in different processes. If the pressure in the system rises above 1.25 inches of water column, the switch inside changes the electrical circuit to cause a response. This response can include turning on alarms, operating fans, or changing the position of dampers in a bid to get the right system performance and efficiency.
