The primary function of the switch is to sense whether the blower fan is blowing air. This is one of the vitally important safety aspects of the whole safety system that is intended to keep you safe. Some different switches are designed with a reset that is manual instead of automatic, which makes you reset it by hand before you can continue using the system.
