A switch is necessary to be able to turn the electrical circuit on and off, otherwise it would stay "on" all the time, until either the source of power stops giving out power - like a battery which goes dead - or part of the circuit stops working, like a light bulb that fails to work after a long time or a that motor siezes-up, overheats and eventually burns out.
Even if you just disconnect a wire from the source of power, you are doing the same thing as a switch.

What does a push switch do in a circuit?
A push switch is an electronic component that completes or breaks an electrical circuit when it is pressed. Pressing the switch physically moves its internal contacts to connect or disconnect the circuit, allowing current to flow or stop flowing. This type of switch is commonly used to turn devices on or off.
It closes the electrical circuit.?
The definition of a switch is a device that closes and opens an electrical circuit.
What is the device to break a circuit?
A switch is a device used to break a circuit. By opening the switch, the circuit is interrupted and electricity stops flowing. This allows for controlling the flow of electricity to different components in a circuit.
What are switches used for in a circuit?
A switch is a means of making (on) or breaking (off) an electrical circuit.
Does closing a switch allows electrical charges to flow in a circuit?
Closing a switch makes a closed circuit Opening a switch opens, or breaks the circuit
Does blu-tack break an electrical circuit?
No, an electrical approved switch is used to break an electrical circuit.
What is a switch's purpose?
A switch is used to make or break an electrical circuit.
What is switch purpose?
A switch is used to make or break an electrical circuit.
What is the three way switch symbol used for in electrical circuit diagrams?
The three-way switch symbol in electrical circuit diagrams is used to show a switch that can control a light or other electrical device from two different locations.
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.
Is the circuit breaker switch loose in your electrical system?
Is the circuit breaker switch loose in your electrical system?
When a switch in an electrical circuit is turned off what will happen?
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
What a switch does in an electrical circuit?
opens and closes the circuit
What does a push switch do in a circuit?
A push switch is an electronic component that completes or breaks an electrical circuit when it is pressed. Pressing the switch physically moves its internal contacts to connect or disconnect the circuit, allowing current to flow or stop flowing.

What is the purpose of a snap switch in an electrical circuit?
The purpose of a snap switch in an electrical circuit is to control the flow of electricity by opening or closing the circuit when activated.
What is a device used to break or open an electrical circuit?
A switch, switching transistor, circuit breaker, and fuse are all used for that job.
It closes the electrical circuit.?
The definition of a switch is a device that closes and opens an electrical circuit.
