The main function of the ignition switch is to provide the initial power to other systems in your vehicle, including radio, accessories and windows. The ignition switch is responsible for turning on the starter motor and engine when the key is turned to the "on position.

The ignition system has to function because it requires a spark to ignite the air and fuel in your car to begin. The spark is generated by the ignition coil which creates a magnetic field around the rotor as the current moves through it. As the rotor spins the magnetic field increases and the ignition spark is released. This spark then turns the pistons of your engine, igniting them up and getting the engine going.

The ignition switch regulates the current of electricity flowing through your primary and secondary circuits. When the switch is set to the "on" position, the battery will send low voltage current through the primary coil's windings and then through the breaker points. This creates a magnetic field that can spin the rotor, and ignite your car's spark plugs that then start firing up the engine.

When the ignition switch is set to'start' the primary and secondary circuits are closed. The electrical connection between distributor cap and rotor terminals is broken as they rotate. This will stop the secondary flow and completes the circuit. This allows the breaker points to close and create a spark at the spark plug, which then ignites the engine within a matter of seconds.
