               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.
