The main job of the pressure switch is to determine whether the primary air circulator is running properly. This is one of the most crucial aspects of the whole safety system that is intended to keep you from harm. Most air pressure switches are constructed with a manual reset, which forces the system to be reset physically or the entire system will not run.
