Air Switches
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.
Our Air Switches are available to perform single or multiple functions sensing.
Pressure Switches
Presair pressure switches make electrical contact when a certain set pressure has been reached on its input. These switches are available either field adjustable or factory set allowing each micro switch to operate at a different setting.
Vacuum Switches
Presair mechanical vacuum switches make electrical contact when a certain set vacuum has been reached on its input. These switches are available either field adjustable or factory set allowing each micro switch to operate at a different setting.
Air Actuators
All air push button actuators have a sealed internal air bellow to prevent water from entering the air tube that connects the air button to the air switch.
