This generates the ignition spark. This spark could turn the pistons of your engine, sparking the engine and causing it to start.
Your ignition switch controls the electrical current that flows through the primary and secondary circuits of your ignition system.

The electrical connection between terminals of the distributor cap and the rotor breaks as they rotate. car ignition replacement stops the secondary flow and completes the circuit. This allows the breaker points to close and create sparks at the spark plug which will then fire the engine within a matter of seconds.
