A rugged, chrome-plated latching pushbutton with a built-in RGB LED ring. Drill a 16 mm hole in any panel up to 6.35 mm (1/4") thick and mount it securely — an included rubber gasket provides a water-resistant seal for enclosures.
The flat metal actuator latches on press and releases on a second press (normally-open contact). The RGB LED ring is electrically separate from the switch, letting you independently control the illumination colour via a microcontroller. Power the common anode at 3–6 V and pull individual cathodes (red, green, blue) to ground — built-in resistors are included. PWM the RGB pins to mix any colour.
Key Features
- Latching Action – Press to close, press again to open (normally-open)
- RGB LED Ring – Common anode with built-in resistors; mix any colour via PWM
- 16 mm Panel Mount – Fits panels up to 6.35 mm thick
- Chrome-Plated Metal – Durable, professional finish
- Water-Resistant Gasket – Rubber seal included for outdoor enclosures
- Electrically Separated – Switch and LED circuits are independent
Specifications
- Mounting Hole – 16 mm diameter
- LED Voltage – 3–6 V (common anode; add 1 kΩ resistor for 12–24 V use)
- LED Current – ~20 mA per colour
- Switch Type – Latching, normally-open
- Contacts – 2 gold pins (switch), 4 pins (RGB LED: 1 anode + 3 cathodes)
- Finish – Black chrome
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.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- 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.
