How the Ignition Switch Works
The ignition switch lies at the heart of your vehicle. It is the first thing you'll touch when getting ready to start your car and the last thing you want to malfunction.

The ignition switch's primary function is to provide electricity to other systems of your vehicle, including the radio, accessories, and windows. The ignition switch is responsible for activating the engine and starter motor when the key is turned to the 'on position.
In order for the ignition system to function there must be spark that ignites the air and fuel inside the engine to cause it to start. The spark is produced by the ignition coil which creates an electric field around the rotor whenever the current moves through it. The magnetic field is created as the rotor rotates. This causes the ignition spark. This spark could turn the pistons of your engine, igniting the engine and causing it to start.
The ignition switch regulates the electrical current flowing through your primary and secondary circuits. When the switch is in the "on" position the battery is able to send an unipolar current to the primary windings and breaker points of your ignition coil. This creates a magnetic field that can ignite spark plugs and spin the rotor.
When the ignition switch is set to "start" the primary and secondary circuits are both closed. When the distributor and rotor cap terminals rotate, the electrical contact between them break and stops the secondary flow and closes the primary circuit. The breaker points will be closed and ignite the spark plug. This will fire the engine within a matter of seconds.
Remember that the ignition switch could be a delicate machine that shouldn't be subjected to extreme force when it is inserted or turned. If you exert too much force, the switch could fail, and you'll need an expert to take it off to make repairs.
