In North America, the use of a two pole single throw switch is used for this purpose. The reason that a two pole switch is used instead of a single pole switch is that code requires that both legs to the 240 volt load has to be broken so as to isolate the load completely from the supply voltage. If a single pole switch was used in this situation one leg of the 240 volt supply would still be "hot" to ground. Someone that is inexperienced with the system could get a nasty shock by just using the switch to isolate the circuit when working on it instead of using the supply breaker to isolate the circuit.
In the UK it is a different scenario as the load across the 240 supply returns to a grounded neutral. In this case just a single pole single throw switch will isolate the circuit.

How do you make sure power is turned off?
if the switch in the circuit is switched off, the power is turned off on the object.
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 components are needed to make an electric circuit works?
Globe Switch Wires(to connect) power Pack
How do you make a 2 way switch which breaks the circuit only when both the switches are turned off?
Send power to the 1st switch and then send the power from that switch when it is in the on position to the second switch. Then send power to the light from the second switch. That way both switches will have to be in the on position for the light to be on.
How a switch controls the flow of electric current?
The switch is designed to make or break the circuit. This gives the operator control over whether the power flows or not.
What materials will you need to make a parallel circuit?
Lightbulb(load),Battery(Power source),Switch,Copper wire
Is a switch needed to make a circuit work?
Not always. Depends on the circuit.
What is switch purpose?
A switch is used to make or break an electrical circuit.
What is a switch's purpose?
A switch is used to make or break an electrical circuit.
What components do you need to make a simple series circuit to light on bulb?
You need a Battery, Light Bulb, Ammeter, Switch.
What do you need to make a simple series circuit to light a bulb?
To make a simple series circuit to light a bulb, the simplest components are a power source (such as a battery); a switch (to turn the power on or off); the bulb (obviously !); and some wires to connect everything together.
What are the componets that make up a circuit?
A circuit can have as little as two components 1 Must have a power source 2. Something for that power source to power, for example a light *Assuming you already know you need wires to complete the circuit
