The Tecmark 3902 and its close cousin, the 3903, were the standard pressure switches used on Gecko control systems for many years.

This pressure switch has a black plastic 1/8" universal thread. The exterior diameter of the thread is 9.5 mm at the widest point. It has terminals which accept either spade or forked connectors.

Many Gecko heaters use this pressure switch, including the 2 kW SSPA and 3 kW universal heaters.

The pressure switch is among the most important pieces of safety equipment found in your spa system. It constantly monitors water flowing through the heater and helps protect the integrity of critical components if ever a problem arises (like overheating).
