What I have seen is every one talks about turning off the circuit. A switch can also provide a life safety by-pass in a circuit. A switch can be energized electromagnetically and provide an alternative path way for electronics flow.
How is it controlled, by a energized magnet to make or break a switch.
A electromagnetic switch can work either AC or DC and does not discriminate. The gap between the known ground and the energized magnet is about one mill-meter. There is usually three connections. Hot, Neutral for electron flow, and a ground.

Switch open = current can not flow. Switch closed = current can flow.
I suppose you need more than that, as if the imagination cannot help you figure out how a door that is shut would not allow you to walk through it.

it interrupts current flow when the switch is turned off..and allows for a closed circuit(current to flow)..when the switch is turned on

Think of a racetrack with a drawbridge. Instead of cars and a drawbridge, replace them with electricity and a switch. If the Switch (drawbridge) is open electrons (cars) can't drive.

It breaks the electrical connection, so electrons cannot flow.
