TRM117A | Tinytrol Miniature Air Switch

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 Miniature Air Switch is available in both single and double pole, with alternate and momentary action. 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.

    Only issue was I ordered on a Saturday and payed for S/H and order was not started until following Tuesday and shipped on Wednesday. I would have preferred item to have been shipped that Monday Tuesday at latest.

    Other than that part was exactly what I need to get septic back up and running
