A switch is a means of making (on) or breaking (off) an electrical circuit.

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.

∙ 15y agoThe simple explanation is the best one. A switch is a device that is designed and engineered to interrupt or break a circuit. When the switch is closed, things are powered up. Open the switch and it stops electron flow by opening the path current was using. It's by either "making" or "breaking" the circuit that the switch controls 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.
When a switch is on is a circuit open or closed?
If the switch is what is keeping the load from turning on, then yes, there is a voltage across the open switch.
What are normally open and close circuits?
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.
Why does an electric circuit have to be closed for it to work?
yes it does have to be a closed circuit
What is the electric circuit where current flows through all parts of the circuit?
complex circuit
What is a device used to open and close an electric circuit?
The device is called a switch.
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.
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 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.
What part in an electric circuit opens and closes the circuit?
A switch, switching transistor, or circuit breaker usually does.
What would happen if there is no an electric switch in a curcuit?
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.
How can you start and stop electric circuit?
Using a switch device which starts and stops the electric current around the circuit
Which electric element should be used so as to open the closed electric circuit?
A switch, circuit breaker, fuse, or switching transistor can do that.
What is the thyristor firing circuit?
The thyristor is basically used a switch in an AC circuit to control the amount of power fed to the load. To turn on this switch an "electric" pulse should be applied to the Gate terminal of the Thyristor. A circuit which supplies the "electric" pulse is called the firing circuit.
How does a circuit turn a switch on and off?
A switch makes a physical break in the electric circuit. With the circuit broken the electricity can not flow. When the switch is turned the other way the circuit is completed and the current/electricity can flow.
What is a switch in a circuit?
A switch is a non automatic mechanical device capable of opening or closing a circuit under normal load conditions
