Cleveland Controls NS2-1563-03 Pressure Switch

The Cleveland Controls NS2-1563-03 Pressure switch is applied in HVAC systems for measuring the flow or pressure. It works based on the variation of pressure between two points. When this pressure differential gets to a certain setpoint, the switch makes an electrical contact and can then operate other equipment. This switch is commonly used in HVAC equipment such as a furnace, an air handler, or a rooftop unit which the part checks the functionality of the fans and filters. Confirming that the system has enough airflow to perform optimally and safely, protecting equipment from damage due to blocked filters or failed fans, and preventing the use of heating elements without proper airflow.
