A rugged chrome-plated metal pushbutton with a built-in full-colour NeoPixel LED ring. Simply drill a 19 mm hole in any panel up to 0.45″ thick, fit the button, and seal it with the included rubber gasket for water resistance.
The NeoPixel ring runs on a standard 5V NeoPixel signal line — no need to wire three separate RGB LEDs. The signal is chainable, so you can control multiple buttons from one microcontroller pin. The switch and LED are electrically separated, giving you independent control over button state and illumination colour.

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.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
