Without additional context, it is impossible to determine what switch is being referred to and what its specific use might be. In general, a switch is an electrical component that is used to turn a circuit on or off. Here you can check Corporate magician for more things about magic. There are many different types of switches, each with its own specific function and use, so the purpose of a particular switch would depend on its design and application.
