Quick overview
- Hydroquip part 34-0002 The factory replacement switch, ordered by part number.
- SPDT Single pole double throw, so one common contact switches between two outputs.
- Rated 25 amps Sized for the load the original switch was carrying.
- Air actuated A deck button sends an air pulse down tubing to trip the switch, which keeps line voltage away from the bather.
- A normal wear item Air switches give up from contact wear and moisture, and the symptom is a button that no longer does anything.
- Check the tubing too A cracked, pinched or water filled air line looks exactly like a dead switch, so test both before you order.

Product details
Hydroquip 34-0002 is a replacement SPDT air switch rated at 25 amps. It is the switch an air button actually operates inside the equipment pack.
How the circuit works
Nothing electrical runs out to the button on the deck. Pressing it sends a pulse of air down a length of small bore tubing to this switch, and the switch handles the load. That arrangement is why an air button can sit within reach of the water in the first place.
Single pole double throw
SPDT means one common contact that connects to one of two outputs. It is worth checking the configuration of the switch you are replacing, because latching and momentary versions and different contact arrangements are used across equipment packs.
Before you order
A dead button is not always a dead switch. Trace the air tubing first and look for cracks, kinks and water sitting in the line. If the tubing is sound and the button still does nothing, the switch is the next thing to change.
