How rotary telephone dials work from a electrical point of view.?

A rotary telephone dial turns your finger movements into electrical signals that tell the phone where to call.

Imagine you're playing with a toy car on a track. When you twist the knob, it moves forward, and the more you twist, the farther it goes. A rotary phone works kind of like that!

When you lift the receiver, the phone knows someone is ready to talk. Then, as you rotate the dial, a small spring inside starts winding up. The faster you turn it, the more winded it gets.

Once you stop turning and let go, the spring unwinds quickly, sending an electrical pulse through wires to the telephone company. That pulse is like a message saying: "Call this number!"

Each full turn of the dial sends one digit (like 1 or 2). If you want to call 345, you turn the dial three times, once for each number.

The phone company gets these signals and connects your line with the person you're calling. Then, you can talk like magic, but it's really just electrical messages working hard behind the scenes!
