A switch in a circuit will quickly allow you to break the circuit, without changing the wiring. For example, a light switch. By turning a light switch off, you are breaking the circuit and, thus, turning the light off.

∙ 11y agoswitches are important because they could break the circuit if too much current is being used ,whch could cause an electrical fire
Wiki User
∙ 12y agoSo the torch can be turned on by the circuit being complete (connected).
Wiki User
∙ 13y agoso you can stop power going through the circuit when you want to and stop the appliance, eg. light bulb, can be turned off without taking circuit apart
Wiki User
∙ 6y agoThe switch is not just useful, but essential to put on or put off the circuit as and when needed.

∙ 7y agoThe switch lets you disconnect the circuit quickly without having to undo anything.

How does a torch work for kids?
In a torch (flashlight), the current passes from the positive terminal, through the bulb, and returns back in the negative terminals, making a complete circuit. When the switch is moved to the on position, a metal piece inside the case touches the positive terminals of the battery, the circuit is completed, and the torch turns on. Move the switch to the off position, the metal piece no longer touches the positive terminals of the battery, and the torch turns off.
How does a switch control the flow of electricity?
When the switch is open, the circuit is not a complete circuit. Electricity needs a complete circuit of conductive material. The switch breaks the circuit causing the flow of electricity to be disrupted. When you close the switch, a full circuit is restored thus restoring the flow of electricity.
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.
Does a switch have to go in a certain place to power a circuit?
If the circuit is complete then it shouldn't matter where the switch is located. All a switch is specifically is a segment of the circuit that can be connected and disconected.
What could you add to the circuit to control the bulb?
Switch
What is the job of the switch in a torch?
the switch in a torch allows the circuit in the torch to be completed
What materials are conductors in a torch?
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
How does a torch work-circuit'?
A torch is simply a circuit containing a battery, a bulb and a switch. The three components are connected in series (one after the other) to form a loop. The switch simply completes the circuit so that power flows from the battery to the bulb.

Why is it important to keep a torch in a dry clean place?
because it dirt can get into the switch so it will break
How does a torch switch work?
It provides the light in the torch
What is an electric torch?
A torch consist of a plastic casing,a bulb ,electric cells. a slide switch and a reflector. Firstly complete the circuit and then put two electric cells or batteries into the plastic case.when you close the switch the circuit will be complete and the bulb will glow. The reflector will pass the light too the big distance and and lighten the distance upto where the light the goes.
Why is it important for the switch of the circuit to be opened at the start?
maybe because its a rule or law...

What does a push switch do in a circuit?
it starts a circuit by connecting the circuit and the initials are ptm and its a spdt switch
