By popular demand, we now have rugged metal buttons with a full-color NeoPixel LED ring light! These chrome-plated metal buttons are rugged, but certainly not lacking in flair.
This is a 19mm Latching version of the RGB pushbutton. Simply drill a 19mm hole into any material up to 0.45" thick and you can fit these in place – there's even a rubber gasket to keep water out of the enclosure. On the front of the button is a flat metal actuator, surrounded by a plastic RGB LED ring.
To use the NeoPixel Color LED: Power the internal NeoPixels with +5V, ground and a NeoPixel signal line - it's a lot easier than wiring up 3 separate RGB LED diodes. Best of all, the NeoPixel signal is chainable, so you can light up multiple switches in one panel.
This pushbutton has both normally-open and normally closed contacts, and unlike our other rugged metal pushbuttons, these come with a detachable 7-wire cable harness to make wiring easy. Follow the datasheet for the wiring pinout.
The switch and LED are electrically separated, so to change the color, use a microcontroller to both read the contact pins and control the NeoPixel.
We also carry a Momentary version.
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- 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, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
