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.


  • Internal LED turns on when the button is pressed down
