A switch is a device which can be used to make or break a circuit.
If that circuit carries a voltage which would be dangerous to people or animals then the handle of the switch must be made of a good insulator and the rest of the switch must be well shielded to stop anyone - or anything else - from touching any live wires.
If you get a chance to visit a science museum ask them to show you a "knife switch". Another place to see one is the Physics Lab at your local college or high school. Once you have seen a knife switch you will understand exactly how a basic switch works. It's quite simple really

∙ 13y agoA switch can be used to allow or disallow current to pass through a certain part of a circuit.

∙ 13y agoA switch simply opens a circuit, stopping the flow of electricity.
For example: a simple circuit would be two wires from a battery, one of which goes to a switch, and the other goes to a light bulb. A third wire goes from the other side of the switch to the other conductor of the light bulb.
With the switch closed the circuit is complete and the light goes on. Open the switch and the circuit is broken and the light goes off.

∙ 13y agoThe job of a switch in a domestic lighting circuit is to stop or start the flow of current and voltage by mechanically creating an open or closed circuit on the live wire that goes to the light fitting.

Electrical switch is used to perform all the logical operations in a digital circuit.
There is no digital electronics with out an electrical switch.
Usually (in positive logic), The logic level is considered as HIGH (1) when switch is OFF, and as LOW (0) when switch is ON.

How does a switch control an electric device?
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.
What opens or closes an electrical 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".

What is a device used to open and close an electric circuit?
The device is called a switch.
What function in a circuit for a switch?
A switch is a make - break device. Its function is a circuit is to make and break the current flow of the circuit that it is in. This action then starts and stops the load that is connected in the circuit.
What is the function of the closed switch in the circuit?
what does closed switch mean
What is the function of electric circuit control device?
the function of the control device is that you can know if the circuit is on or off
What happens to an electric current at a light switch?
When an electrical switch is in the off position, the circuit is interrupted. When the switch is on, the circuit is open and complete.
What is happening when you turn an electric circuit off?
When you switch off an electrical circuit you tend to create a 'break' in the circuit, preventing the electric current to flow around the circuit, this can be caused by a simple switch or a break in the circuit, e.g a disconnected wire.
What is the function of resistor in electric circuit?
the function of a resister is to lower the voltage.

What is the function of the voltmeter in an electric circuit?
A voltmeter is a device to measure the voltage in a electric circuit, and must have be connected in parallel to it.
What device opens and closes an electric circuit?
A switch is a device that is used to open and close an electrical circuit that is is connected into.
