We are Closing(Completing) the circuit so as to make the electric appliance start working.
Explanation:
When we Switch ON the electric appliance the circuit gets closed(complete) and Voltage gets induced in it and currents starts to flow in it because of which the electrical appliance starts working.
For Example:
Attached is the diagram of Light bulb circuit with switch.
When Switch is "OFF".
The Circuit is an open circuit and voltage is not induced because of which current is not flowing and result of this is that Light bulb doesn't glow.
When Switch is "ON".
The Circuit is a closed circuit and voltage is induced in it because of which current starts to flow and result of this is that Light bulb starts glowing.
