Description
The Amana-Goodman 20197311 SPST Pressure Switch is an essential part of the HVAC systems and is used to measure pressure and switch in the airflow of a system. It is a Single Pole Single Throw switch which works on the principle of pressure differences in the ducts. When the pressure drops below a certain level, the switch turns on, and sends a signal to the HVAC system. It can trigger a number of functions to get a particular blower motor or change the damper positions for right airflow and required running of the framework.
