Amana-Goodman C6456508 SPST Pressure Switch -0.54" WC

The Amana-Goodman C6456508 SPST Pressure Switch is an essential part of HVAC systems because its main function is to measure and regulate airflow. This pressure switch is a single-pole single-throw type that carries one normally open contact that will close when the pressure in the system is at a certain level. It functions within a pressure range of -0.54 inches of water column and is capable of detecting small changes in pressure. In other words, this is a kind of protection and optimization switch. When airflow obstruction is present, for example, a blocked filter, or a defective blower motor, the pressure inside the system can either decrease or increase. This pressure switch measures these pressure fluctuations and responds in the correct manner.
