The device is called a switch.
Generally we use electric switches to put on or off the light,fan,computer,music system,etc.An electric switch is a device that is used to open or close an electric circuit.when we open an electric circuit the flow of electric current inthe circuit stops and when we close an electric circuit an electric current flows through it.
When a plug key is open , the circuit is incomplete and is call open circuit.. To be continued..
An open circuit.
The type of circuit you are describing is known as a simple circuit. It consists of a power source (electric cell), a switch, a conductor (usually wire), and a resistor to control the flow of electric current.
A switch, circuit breaker, fuse, or switching transistor can do that.
A switch is a device that is used to open and close an electrical circuit that is is connected into.
A switch.
A switch in an electrical circuit is a device that can open or close the circuit, allowing or preventing the flow of electricity. When the switch is closed, it completes the circuit, allowing the electricity to flow, while when it is open, it interrupts the flow of electricity. This allows users to control the flow of electricity to a particular device or component in the circuit.

A basic manual operating switch is able to open or close a circuit. There are electronic components that will also control the working of a circuit.
That function was traditionally implemented in the form of a mechanical deviceknown as a "switch".The practice became so firmly embedded in the art and science of electricitythat the word became the generic term for any device that could performany similar function, so that now we have "switching transistors", integrated"CMOS switches", and even central office telephone-circuit "switches".
The electric path which starts from the positive terminal of a cell or battery ends at its negative terminal, without any break, is called closed electric circuit or complete electric circuit. The electric path,which starts from the positive terminal of a cell or battery, is broken at some point, is called open electric circuit or incomplete electric circuit.
A light switch
A closed circuit is a kind of electric circuit in which the path that the electrons follow forms a complete circuit.
A device that opens and closes a circuit is called a switch.
which electric element should be used so as to open the closed electric circuit
A switch basically represents a gap in the electric circuit. Electric current can pass through a circuit only if it is complete. An incomplete circuit can never pass a current through it. When the switch is in the 'off' position, the circuit has a break (gap) in it. When you put the switch in 'on' position, the circuit wire join and the circuit gets completed.
