PresAir Air Switch - TVA111A

TVA111A Tinytrol Miniature Air Switch, 1/2 Mounting Threads with 90° Flats. Alternate Latching Air Switch, SPDT, 21 amps

Replacement air switch for use on many pumps, blowers or control systems.

This switch has 3 spade connections present:

• Normally Open
• Normally Closed
• Common

This is very handy if you need to utilise both the NO & NC connections e.g. 2 speed pump change over switch as seen on some Hydropool hot tubs, many other switches available have the normally closed terminal removed.

The Presair Air Switching system uses an air bellow actuator joined by tubing to an air switch contained within the equipment or appliance to be switched. Pushing the actuator creates enough pressure to operate the air switch which safely controls the equipment. There is complete electrical isolation with no voltage ? low or high ?  to worry about at the point of actuation. No external compressed air is required.

The Tinytrol air switches are miniature single or double pole alternate action & momentary action air switches.  Typical distance between Presair actuators and Tinytrol air switch for alternate action is 20 feet, for momentary action distances of tubing up to 35 feet.  Distances of 100 feet are available, please consult factory for more information.
