To allow the ignition system to work, there must be spark that ignites the air and fuel inside the engine to cause it to start. The spark is generated by the ignition coil which creates an electric field around the rotor when the current flows through it. As the rotor spins the magnetic field builds up, and then the ignition spark is released. This spark then turns the pistons inside your engine, igniting them up and getting it going.

The ignition switch controls the electrical current running through your secondary and primary circuits.

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 will be shut off. When the distributor and rotor cap terminals rotate, the electrical connection between them is broken and stops the secondary flow and then completes the primary circuit. The breaker points are able to close, causing sparks at the spark plug, which will then ignite the engine in just a few seconds.
