About this pressure switch

The Tecmark Pressure Switch 3029 is a single-pole single-throw (SPST) pressure switch designed for spa and hot tub chemical feed systems. This 25-amp rated switch activates at 1-5 PSI pressure range through its 1/8" NPT connection, making it compatible with most standard spa chemical dosing equipment and sanitization systems.

Built to OEM specifications, this Tecmark pressure switch delivers reliable performance for automated chemical dispensing in residential and commercial spa applications. At Bubbles Supply, we guarantee an exact fit for your system with same-day shipping on in-stock items, plus our comprehensive 1-year warranty for complete peace of mind. Verify your existing switch's pressure range and electrical requirements before installation to ensure proper chemical system operation.
