About this pressure switch

The Tecmark 3038 Pressure Switch is a single-pole, single-throw (SPST) chemical automation component designed for spa and hot tub sanitization systems. This 1-amp rated switch activates at 1-5 PSI pressure range, making it ideal for controlling chemical feeders, ozonators, and other low-pressure spa equipment across most residential hot tub brands.

Built to OEM specifications, this genuine Tecmark pressure switch ensures reliable performance in demanding spa environments. At Bubbles Supply, we guarantee an exact fit for your system and back every switch with our comprehensive 1-year warranty. Most orders ship same-day from our Canadian warehouse, getting your spa back to optimal chemical management quickly. Verify your existing switch's pressure rating and electrical specifications before installation to ensure proper system operation.

Before you buy — quick checklist

  • Confirm your existing switch is rated 1A — do not substitute a higher-amp switch without verifying system compatibility
  • Verify your system operates in the 1–5 PSI activation range — check your existing switch label or equipment manual
  • Confirm SPST wiring configuration matches your control system
  • Check the port size and thread type on your existing switch before ordering
  • Inspect the tubing or sensing port for damage or blockage before replacing the switch — a blocked port can mimic switch failure

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