The ignition system needs to function because it requires a spark to ignite the air and fuel in your car to begin. The ignition coil generates the spark by creating an electromagnetic field that surrounds the rotor while the current moves through. The magnetic field is created as the rotor turns. This causes the ignition spark. This spark can then turn the pistons of your engine, igniting them up and getting it started.
The ignition switch regulates the current of electricity flowing through your secondary and primary circuits. When the switch is set to the "on" position the battery sends low voltage current through the primary coil's windings and then through the points of the breaker.

This allows the breaker points to close, causing sparks at the spark plug, which will then ignite the engine in just a few seconds.
