What is They used switches?

They use switches to turn things on and off, just like you use a light switch to make your room bright or dark.

Imagine you have a toy that plays music. When you press the button, it starts playing. That button is like a switch, it tells the toy what to do. In real life, switches are used in lots of places, like on your phone, fridge, and even in computers!

Think of a switch as a door between two rooms. When the door is open, the music can travel from one room (the toy) to the other (your ears). When you press the button (or flip the switch), the door opens or closes, that's how it turns things on and off.

Some switches are like buttons you push, others are like levers you flick up or down. No matter what they look like, their job is always the same: to let electricity flow through or stop it, just like a door lets people pass through or stops them!
