The main purpose of the ignition switch is to supply the initial power to the other systems of your vehicle, including radio, accessories, and windows. The ignition switch also turns on the engine and starter motor when the key is in the "on" position.
To allow the ignition system to work it must have a spark that can ignite the air and fuel inside your car's engine to start. The ignition coil produces the spark by creating a magnetic field that surrounds the rotor while the current flows through. As the rotor spins the magnetic field grows, and then the ignition spark is released. This spark then turns the pistons inside your engine, firing them up and getting the engine started.
The ignition switch controls electrical current that flows through the secondary and primary circuits of your ignition system. When the switch is in the "on" position the battery transmits a low voltage current to the primary windings and breaker points of your ignition coil. This creates magnetic fields that spin the rotor, and ignite your car's spark plugs that then start firing up the engine.
When the ignition switch is set to'start' the primary and secondary circuits are closed. The electrical contact between the terminals of the distributor cap and the rotor is broken as they spin. This will stop the secondary flow and completes the circuit. This allows the breaker points to close and produce a spark at the spark plug which will then ignite the engine in a matter of seconds.
Remember that the ignition switch could be a delicate piece of equipment that shouldn't be subjected to too much force when it is turned. If you use too much force, the switch could fail and you'll require an expert to take it off for repairs.
