The ignition switch is also responsible for activating the starter motor and engine when the key is turned to the “on' position. The ignition system has to function because it needs sparks to ignite air and fuel inside your car for it to start. The spark is generated by the ignition coil which creates a magnetic field around the rotor whenever current passes through it. As the rotor spins the magnetic field increases and the ignition spark is released. This spark then turns the pistons in your engine, firing them up and getting it started. 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 a low voltage current to the primary windings and breaker points of your ignition coil. This creates an electric field that could spin the rotor, and ignite your car's spark plugs which then heat up the engine. When the ignition switch is set to “start” the primary and secondary circuits are closed. As the rotor and distributor cap terminals rotate, the electrical connection between them break, which stops the secondary flow and completes the primary circuit. The breaker points will close and spark the spark plug. This will fire the engine within a matter of seconds.
