About this maintenance/tool

The PresAir VS11106E vacuum switch is a professional-grade sensor designed for spa and hot tub applications requiring reliable air pressure detection. This SPDT (Single Pole Double Throw) switch handles up to 21 amps and features a standard 1/8" NPT connection, making it suitable for various spa control systems where vacuum sensing is critical for proper operation.

Built to OEM specifications, this PresAir vacuum switch delivers the exact fit guaranteed you need for seamless replacement in your spa's pneumatic control system. We ship same-day from our Canadian warehouse and back every part with our comprehensive 1-year warranty for complete peace of mind. Ensure your spa's existing plumbing connections match the 1/8" NPT threading before installation, and verify proper electrical compatibility with your control system's amperage requirements.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

Spa jets won't activate via pneumatic button
Air button press has no response
Spa feature (blower, light, pump) fails to toggle on or off
Intermittent or unreliable response from air button
Control system activates randomly without button press

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

Confirm your existing switch uses a 1/8" NPT port connection — mismatched threading will prevent installation
Verify your control system's amperage draw does not exceed 21A
Check whether your current switch is SPDT (Single Pole Double Throw) — this switch will not substitute for SPST or DPDT configurations
Trace the air tubing from your pneumatic button to the switch to confirm vacuum-type actuation is used (not direct contact or digital)
Inspect the air tubing for cracks or disconnections before replacing the switch — a leaking tube can mimic switch failure

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
