Many hot tubs and spas utilize an air switch to control various functions of the tub. An air switch consists of a pneumatic air button located at spa-side and a pneumatic-activated electrical, air switch located with the spa electronics. The only connection between the two is a small air hose.
What are the air controls on a spa?
Hot tub air controls, which are located at the top of your spa, manage the force of your jets, the air to water ratio, and mix. They act as an air valve, allowing the spa user to dial in that perfect mix and ratio, increasing the action and pressure from the jets in your spa.
How does air switch on hot tub work?
An air switch consists of a pneumatic air button located at spa-side and a pneumatic-activated electrical, air switch located with the spa electronics. This arrangement eliminates the shock hazard of activating a regular switch energized with 120 volts or 220 volts with wet hands while submerged in water.
How do you test an air switch?
With air applied to the pressure switch, place one lead of the ohm meter to one of the loose wires, and the second lead to the second loose wire. The air pressure switch should close when air is applied. If the switch closes, the ohm meter will read zero ohms, indicating the air pressure switch is good.
How does an air switch function?
When the Air Button is pressed, air is compressed in a thin air tube that is connected to the switch. The compressed air triggers the air switch which turns on a power point that activates the device. This means you can sitting in the water an operating an electical device as there is no chance of electric shock.
What is an air switch on a hot tub?
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.
Why isn’t my air switch working in my spa?
More times than many, 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.
How do pneumatic switches work?
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.
How do presair air switches work?
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.
