Answer 1

Hint
A switch is something that controls the flow of electric current. It is used to connect or disconnect a circuit. Switches can be of different types from a normal ON OFF to calculator switches.

Complete step by step answer
Switch monitors the path of an electric circuit. It helps in connecting or disconnecting the flow of current. Toggle is a kind of switch which consists of a lever or handles to control the current flow. It is used to switch between on and off. Pushbutton is a simple type of switch. In many cases pushbuttons are connected together such that pressing one button stops another button. Joystick is an input device which has a stick that rotates connected to a base, often containing buttons. It is used in controlling vehicles, machines etc. Movement of joystick is nothing but a signal for the circuit which makes the joystick a kind of switch. Thus toggle, push button, joysticks are few types of switch.
Hence option (D) is correct.

Note
Switches need not be of ON and OFF like in houses. One switch can control more than one circuit. Switches are not only for controlling power from an external source to a device but also within a device.
