Answer:

The switch simply makes of breaks the electrical connection between the electrodes.

Explanation:

The switch in question would typically be inserted into the live wire between the power supply and the device being controlled.

When the switch is in the 0 position, there is not electrical connection between the two electrodes on the switch which means that no current flows and the device is off.

When the witch is in the 1 position, there is an electrical connection between the two electrodes on the switch which means that current does flow and the device is on.

This is the normal situation for light switches etc.
