Carrier 48GP048130300 Air Pressure Switch
The job of the pressure switch is to sense whether the primary air circulator is running properly. Some particular air pressure switches have a manual reset feature, which means it will have to be manually reset or the entire system will not run. This pressure switch is just one of many devices designed to stop injuries or explosions.
