The act of switching the key to the "off" position cuts the electrical power to the ignition system, thereby stopping the spark required for combustion in a gasoline engine. A diesel engine is stopped by cutting off the fuel supply since there is no spark.

When you turn the key off, power is interrupted to the coil, which means no high voltage spark to the plugs. Also the fuel pump stop running, so no fuel. No spark + no fuel = engine stops.

On a gasoline engine, the power is cut off to the ignition system.
With diesel engines and modern gasoline engines, the fuel pump and fuel injection system are also switched off.

It stops the power to the coil wich stops the spark plugs from sparking. No spark, no explosion. It also stops teh injectors from injecting fuel.

kills power to the igniton system and the fuel system if the vehicle is fuel injected or has an electric fuel pump.
