The pressure switch is a switch which closes when a certain set pressure has reached on its input. The switch is most likely to have been designed to make contact on pressure rise or on pressure fall.
Another pressure switch detects force e.g. A pressure sensitive mat is used to automatically open doors on commercial buildings.
The pressure switch might have a differential range around its set point in which small changes of pressure do not change the state of the contacts. Some types allow adjustment of the differential.
