The ignition system needs to function because it requires sparks to ignite air and fuel in your car to begin. The spark is generated by the ignition coil, which creates a magnetic field around the rotor whenever current passes through it. The magnetic field is created as the rotor rotates. This generates the ignition spark. This spark can rotate the pistons of your engine, sparking them and starting it.

The ignition switch regulates the electrical current flowing through your secondary and primary circuits. When the switch is in the "on" position, the battery sends low voltage current through the primary coil's windings and then through the points of the breaker. This creates an electric field that could spin the rotor, and ignite the spark plugs of your car which then heat up the engine.

When the ignition switch is turned to "start", the primary and secondary circuits will be shut down. As the rotor and distributor cap terminals rotate, the electrical contact between them is broken and stops the secondary flow and then completes the primary circuit. The breaker points close and spark the spark plug. This will start the engine within a matter of seconds.
