When an electrical switch is in the off position, the circuit is interrupted. When the switch is on, the circuit is open and complete.

Complete circuit.
When the switch is open, the circuit is not a complete circuit. Electricity needs a complete circuit of conductive material. The switch breaks the circuit causing the flow of electricity to be disrupted. When you close the switch, a full circuit is restored thus restoring the flow of electricity.
To turn on a light switch, simply flip the switch upwards or to the right, depending on the type of switch. This will complete the electrical circuit and illuminate the light.

very carefully!!
If the circuit is complete then it shouldn't matter where the switch is located. All a switch is specifically is a segment of the circuit that can be connected and disconected.
A switch is placed in an electrical circuit in order to place a gap when the switch is off, so the circuit is broken. When the switch is on, the circuit is complete and the electricity can flow round the circuit.
