About this pressure switch

The Balboa SPST Pressure Switch 30408 is an OEM chemical system pressure switch designed for spa equipment requiring precise pressure monitoring at 2 PSI activation. This single-pole, single-throw switch handles 3 amp electrical loads and works with Barksdale/Balboa chemical feed systems to ensure proper sanitizer delivery when water pressure conditions are met.

Built to exact OEM specifications, this genuine Balboa pressure switch delivers the exact fit guaranteed for reliable chemical system operation. We ship same-day from our Canadian warehouse and back every part with our comprehensive 1-year warranty for complete peace of mind. Verify your existing switch's amperage rating and PSI setting before installation to ensure proper chemical system function.

Before you buy — quick checklist

  • Confirm your existing switch is rated 2 PSI activation — do not substitute a different PSI setting
  • Verify your system uses a single-pole single-throw (SPST) configuration, not SPDT
  • Confirm the load does not exceed 3 amps — check your chemical feed pump or ozonator draw
  • Check whether this switch is plumbed inline or mounted to a barb/tee fitting on your existing system
  • Verify this is a Balboa or Barksdale chemical system before ordering

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