The Amana-Goodman 11112501S SPST Pressure Switch is important for HVAC systems and it is made to regulate airflow as a pressure switch. This SPST pressure switch is very sensitive and will switch at as low as -0.33 inches of water column pressure. In other words, it is a safety part that stops the system’s operation if the airflow is below a certain point. This is to avoid cases where the equipment is overheated and may cause some serious damage. In more detail, the pressure switch works under the facts of the changes in the air pressure level in the HVAC system. When the airflow reduces the pressure within the system also reduces.
