About this pressure switch

The DETC-2 Pressure Switch 510AD0249 is a genuine Gecko Alliance chemical dosing pressure switch designed for spa systems that require precise chemical monitoring and control. This SPST (Single Pole Single Throw) switch operates at 1 amp capacity with a 2.0 PSI activation threshold, making it ideal for automated chemical feeders and sanitization systems in hot tubs and spas equipped with Gecko control systems.

Built to OEM specifications, this pressure switch ensures reliable chemical system operation by monitoring water pressure and triggering chemical dispensing as needed. At Bubbles Supply, we guarantee an exact fit for your spa's chemical system, with same-day shipping on in-stock items and a full 1-year warranty for complete peace of mind. Verify your existing switch specifications and wiring configuration before installation to ensure proper chemical system function and safety.

Before you buy — quick checklist

  • Confirm your existing switch is rated 1A / 2.0 PSI — do not assume all DETC switches share the same rating
  • Verify your spa uses a Gecko Alliance control system with an integrated chemical dosing circuit
  • Check the wiring configuration on your current switch before removal — photograph connector orientation
  • Confirm the part number 510AD0249 on your existing switch or system documentation before ordering
  • Inspect the chemical feeder line fittings to ensure the replacement switch will thread or connect without adapter hardware

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