Okay kiddo, imagine you are in a room with three doors. Each door takes you to a different place. Let's call these doors A, B, and C.
Now, imagine you have a magical switch in your hand. When you press this switch, it opens one of the doors randomly.
If you press the switch and door A opens, you can go through that door and see where it takes you. If you press the switch again, it might open door B or C, and you can choose to go through that door instead.
This switch is like a decision-maker. It helps you randomly choose one option out of several. Just like how you can randomly open a door and explore what's behind it, a switch can randomly select one option out of many to help you make a choice.
In electronics, a switch is a component that can turn something on or off, and it usually has two states. It can be compared to a light switch that turns the lights on and off in your room.
So, when people say "switch56", they might be talking about a specific type of switch that has 56 different positions. This means that it can randomly select one of 56 different options, just like how your magical switch can randomly open one of three doors.
