Tactile Switch Full Demonstration | Pin Explanation + LED Control Setup

In this video, I show how a tactile push button works on a breadboard by connecting it with three LEDs, resistors, and an Arduino Nano. You’ll see how each pin of the tactile switch behaves internally, how the LED reactions change when the jumper wire is moved, and why some LEDs glow directly while others work like a proper switch.

This simple and visual explanation will help beginners clearly understand tactile switch pin mapping, internal connections, and practical LED testing.

⭐ What you’ll learn:

How a tactile switch works internally

How pins 1–2 and 3–4 are internally connected

How to connect LEDs and resistors correctly

Why some LEDs turn ON directly

How to control LEDs using different switch pin combinations

Basic breadboard wiring with Arduino Nano


If you're a beginner or making your first electronics project, this demonstration will help you understand tactile switches in the easiest way!
