Tinytrol Miniature Air Switches

Presair Tinytrol Miniature Air Switches are single function controls that provide safe on/off actuation of electrical devices from remote locations such as motors, lights, pumps, or other applications.

Presair air switches are designed to use an air bellow actuator joined by tubing to an air switch contained within the equipment. Pushing the actuator creates enough pressure to operate the air switch which safely controls the equipment. There is complete electrical isolation with no voltage to worry about at the point of actuation.


Wide variety of options available to meet original equipment manufacturers product requirements.


Highly stable with good repeat accuracy. All switches are 100% tested at high & low settings, &  at proof pressure.


Remote operation with complete electrical isolation. UL Recognized. Costs less than conventional controls


Presair switches are designed & manufactured in Eau Claire, Wisconsin, U.S.A.

Presair Tinytrol miniature air switches deliver complete electrical isolation with zero voltage at the point of actuation.

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.

Frequently Asked Questions


What is a momentary action versus alternate latching action?

A momentary action air switch is when the circuit opens or closes while air pressure is being constantly applied. Whereas an alternate latching action is when air pressure is applied the circuit changes states, and requires air pressure to be applied again to change the circuit’s state again.

How do I choose the right air switch?

There are a few factors that come into play when choosing the correct air switch for your application. Here is a quick checklist:

  1. How will you mount the switch in your system?
  2. Will you need the switch to operate momentary or alternate latching?
  3. What is the current rating of your system the air switch is controlling?
  4. What is the distance of air tubing from the pressure source to the air switch?
