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 install a 2 wire 3 way switch in a circuit?
To install a 2 wire 3 way switch in a circuit, first turn off the power to the circuit. Then, connect the two wires from the switch to the two wires in the circuit. Make sure to follow the wiring diagram for the specific switch model. Finally, secure the switch in place and turn the power back on to test the switch.
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.
How to eliminate a 3-way switch in a circuit?
To eliminate a 3-way switch in a circuit, you can rewire the circuit to remove the switch and connect the wires directly. This will convert the circuit to a standard single-pole switch setup. Make sure to turn off the power before working on the circuit and follow proper safety precautions.
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
What does a push-to-make switch do in a circuit?
A push-to-make switch completes the circuit and allows electricity to flow through when the switch is pressed or engaged. When the switch is released, the circuit opens, interrupting the flow of electricity.
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 can I properly wire a switch in my electrical circuit?
To properly wire a switch in your electrical circuit, first turn off the power to the circuit. Connect the hot wire to one terminal of the switch and the load wire to the other terminal. Make sure to ground the switch if necessary. Secure the connections with wire nuts or screws. Test the switch to ensure it is working correctly before turning the power back on.
