International Comfort Products PAPC Air Pressure Switch

The reason for the existence of an air pressure type switch is to figure out if the main blower is doing what it is supposed to do. Most air pressure switches may have a reset feature that is manual, by which you must manually reset it or else the system will cease to function. This pressure switch is part of a small, but important collection of aspects of the whole safety system that is intended to stop injuries or explosions.
