When the ignition switch is set to "start", the primary and secondary circuits are both closed. When the distributor and rotor cap terminals rotate, the electrical connection between them is broken and stops the secondary flow and closes the primary circuit. The breaker points are able to close, causing sparks at the spark plug which then ignites the engine in just a few seconds.
