When closing the switch, the light bulb turns off, switching it's state from I to O.
WHY AND HOW DID IT HAPPEN?
Everything that is electrically powered needs electricity, the switch acts as a toggle signal for the electricity whether it should pass or not depending on which state the switch is on.
I = state means turned on.
O = state means turned off.
