The primary function of the ignition switch is to provide power to other systems of your vehicle like the radio as well as accessories and windows. The ignition switch is 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 the fuel and air in your car to start. The spark is created by the ignition coil, which creates an electric field around the rotor when current passes through it. As the rotor spins, the magnetic field grows, and then the ignition spark is released. This spark can then turn the pistons of your engine, firing them up and allowing it to get to start.
The ignition switch controls the electrical current running through your secondary and primary circuits. When the switch is set to the "on" position, the battery is able to send low voltage current through the primary windings of your ignition coil and then through the breakers. This creates a magnetic field that can ignite spark plugs and spin the rotor.
When the ignition switch is set to "start" the primary and secondary circuits are closed. The electrical contact between the terminals for the distributor cap and rotor break when they turn. This will stop the secondary flow and completes the circuit. The breaker points will close and ignite the spark plug. This will start the engine in a matter of seconds.
