Amana-Goodman 20197314 SPST Pressure Switch -0.16" WC

This Amana Goodman 20197314 SPST Pressure Switch is used in HVAC systems, to measure and control pressure in these systems. It works as a single pole single throw switch and opens or closes the circuits depending on the pressure set for it. In HVAC systems this switch usually measures static pressure in the ducts. If the pressure goes below a certain level the switch operates and the system alters the airflow or performs other corrective measures. This means minimizing the chances of a case where things like inadequate airflow or undue stress to some component is experienced to compromise the system.
