The main job of the switch is to determine whether the primary blower is running. The air pressure switch is part of the safety system in place to keep you safe from any injuries. A good number of pressure switches today are constructed with a manual reset, which means it would need to be reset before you can continue using the system.
How to Know when the Switch is About to go Bad
