## Description

#### Introduction

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.
