               Switch:
                   Switch is an electrical device which can make or break a circuit.
                   A simple switch consists of two terminals that are internally connected to a thin
                    metal strip.
                   It is used to operate an electrical device.
                   When the switch is in ON position, it allows the current to flow through it, forming
                    a closed circuit.
                   When the switch is in OFF position, it doesn't allow electric current to flow
                    through it, forming an open circuit.
                   There are many types of switch: Tap switch, toggle switch and push button etc.
