The basic function of the ignition switch is to supply the initial energy to other systems within your vehicle, such as radio, accessories and windows. The ignition switch also turns on the starter motor and engine when the key is in the "on" position.
The ignition system has to function because it requires a spark to ignite the fuel and air in your car to begin. The ignition coil produces the spark by creating an electric field that surrounds the rotor as the current flows through. The magnetic field is created when the rotor spins. This generates the ignition spark. This spark can turn the pistons of your engine, igniting them and triggering it.
Your ignition switch controls the electrical current that runs through the secondary and primary circuits of your ignition system. When the switch is in the "on" position the battery transmits an unipolar current to the primary windings and breaker points on your ignition coil. This creates a magnetic field that can ignite the spark plugs and spin the rotor.
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 contact between them break and the secondary flow and closes the primary circuit. The breaker points will close and spark the spark plug. This will ignite the engine in a matter of seconds.
