🔁 How It Works

• When button is pressed → Circuit closes (ON)

• When released → Circuit opens (OFF)

This type of switch is called a momentary switch because it only stays ON while being pressed.

📌 Pin Configuration

The 4 pins are internally connected in pairs:

• Two pins on one side are connected together

• Two pins on the opposite side are connected together

Pressing the button connects both sides, completing the circuit.
