In order for the ignition system to function it must have spark that ignites the air and fuel in the engine of your vehicle to begin. The ignition coil creates the spark by creating an electric field that surrounds the rotor as the current moves through. When the rotor spins the magnetic field builds up, and then the ignition spark is released. This spark could rotate the pistons of your engine, which can ignite the engine and causing it to start.

The ignition switch regulates the current of electricity flowing through your secondary and primary circuits. When the switch is in the "on" position the battery is able to send low voltage current to the primary windings as well as the breaker points of your ignition coil. This creates magnetic fields that spin the rotor, and ignite your car's spark plugs, which will then fire up the engine.

When the ignition switch is set on "start" the primary and secondary circuits will be shut down. As the rotor and distributor cap terminals rotate, the electrical connection between them breaks and the secondary flow and then completes the primary circuit. The breaker points are able to close and produce sparks at the spark plug, which then ignites the engine in just a few seconds.
