Presair single pole, double throw (SPDT) air switches are single function controls that provide safe actuation of electrical devices from remote locations. SPDT air switches are connected to an air button with air tubing and will control components like a pump. The air switches are available either momentary or alternate latching.

Presair air switches deliver complete electrical isolation with zero voltage at the point of actuation. The air switching system connects the air switch to an air bellow using air tubing. When the air bellow is pressed, it sends a pulse of air through the tubing actuating the air switch.

Presair air switches cost is comparable or lower than conventional controls to meet the needs of the original equipment manufacturer.

Presair’s air switching system is commonly used in pool and spa application, home appliances, medical applications, industrial applications, and many others!
