In order for the ignition system to function it must have spark that ignites the air and fuel inside the engine to cause it to start.

This causes the ignition spark. The spark will rotate the pistons of your engine, which can ignite them and starting it.
The ignition switch controls the electrical current that runs through the primary and secondary circuits of your ignition system.

When the ignition switch is set to "start", the primary and secondary circuits will be closed. The electrical connection between terminals of the distributor cap and the rotor break as they spin. This stops the secondary flow, and completes the circuit. The breaker points will be closed and spark the spark plug. This will ignite the engine within seconds.
