This is a simple LED-illuminated self-lock switch button. It’s just like a basic switch button, but it lights up color(red/yellow/green/blue/white) when pressed down, which gives you visual feedback. These little buttons can be used with micro: bit to realize various fun interactive projects, such as switch, backlight keyboard, music player panel, and recording control panel.
Note: The module comes with self-lock function. When the button is pressed down, the module outputs High, and the LED lights up. When being pressed again, the module outputs Low and the LED turns off.

Plain-language definitions for the technical terms used above.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- 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.
