Pool or Spa Air Switch

Did Your Jets Stop Working? 

Did your jets suddenly stop working with the press of a button? It is most likely an air switch that is causing the problem. Many air switches are used to control various functions of hot tubs or spas. The air switch assembly has an pneumatic push button located spa side and a pneumatic air switch located in the spa’s controller. There is a piece of air tubing that leads from the push button to the switch. This pneumatic control is a safe switching mechanism as it eliminates the possibly of user’s experiencing electrical shock, as there is no electricity at the point of actuation.

Troubleshooting your Spa Air Switch

More times than not, when customers call Presair, we are able to help them find a solution to why the air switch in a spa isn’t working. Typically the operator is finding a kink or leak in the airline that is not allowing air to pass to the air switch to open or close the contacts. This can be easily fixed by either replacing the tubing or relocating it.

Keep in mind, the issue can be with the push button or the switch. To determine where the failure is happening, follow the steps below:

  1. First, the operator can press on the air button assembly and listen for a ‘click’ sound in the air switch.
    1. If the ‘click’ happens, then the push button is sending enough air to trigger the air switch.
    2. On the other hand, if no click is heard, the air switch isn’t sensing air pressure therefore the issue lies with the air tubing or push button.
    3. If the switch doesn’t click, but makes a hissing sound like air is leaking from the air switch, then unfortunately the air switch diaphragm has blown and a new switch is necessary.
  2. Determine the type of switch for the suspect switch by looking up the identification number or by contacting the pool/spa dealer.

Hear a ‘Click’ but there is still nothing happening? 

  1. Verify the correct operation of the switch circuit.
  2. Connect the multi meter to a set of power leg/switch leg poles.
  3. Since there are only two poles on a SPST air switch, make the connection to each pole. Operate the air button.
  4. The multi meter should, alternately, show continuity and no continuity, as the air button is operated.
  5. If the multi meter does not show continuity of the air switch, replace the switch.
Spa Air Switch 

Tinytrol Air Switch

Presair 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. Additionally, there is complete electrical isolation with no voltage to worry about at the point of actuation.
