Carrier 58STA110 Air Pressure Switch
The main function of this type of switch is to determine whether the air blower is doing what it is supposed to do. A lot of switches are equipped with a manual reset feature, which means it would need to be reset before the HVAC system will continue. This pressure switch is one of the critical safety creations designed to keep you from harm.
