A Miniature pressure switch interfaces from pressure signals to electrical control circuits and from vacuum signals to electrical systems. The switch operation is based on the actuation of a precision snap-acting switch acting against a diaphragm. The extremely short stroke and small volume permit fast response making it ideal for precise pressure and vacuum sensing.

Presair designs and manufactures a wide variety of switches that focus on pneumatic actuation. Specifically, Presair specializes in foot switches, air switches, hand or palm switches, pressure switches and vacuum switch for many different applications. All of these different types have different product categories depending upon the type of application you are using. All Presair switches are made in the U.S.A.
