This chrome-plated metal pushbutton is built tough and looks great doing it. Simply drill a 16mm hole into any panel up to 12.7 mm thick, drop it in, and tighten the included nut — a rubber gasket keeps water out of your enclosure. The flat metal actuator is surrounded by a blue LED ring that lights up when powered.
The switch and LED are electrically separate, giving you full control over when the ring illuminates — wire it to light on press, stay always on, or whatever suits your project.

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
