The main purpose of the ignition switch is to supply the initial power to the other systems of your vehicle, such as accessories, radio and windows. The ignition switch is also responsible for turning on the starter motor and engine when the key is turned to the 'on' position. The ignition system must work because it needs a spark to ignite the air and fuel in your car to begin. The spark is created by the ignition coil which creates a magnetic field around the rotor whenever the current flows through it. As the rotor spins, the magnetic field increases and the ignition spark is released. This spark can change the pistons of your engine, sparking them and triggering it. Your ignition switch controls the electrical current that flows through the primary and secondary circuits of your ignition system. When the switch is in the “on” position the battery sends low voltage current through the primary coil's windings and then through the breakers. This creates a magnet 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. The electrical contact between the terminals for the distributor cap and rotor is broken as they spin. This will stop the secondary flow and completes the circuit. The breaker points will be closed and spark the spark plug. This will start the engine within seconds. It is important to remember that the ignition switch is a delicate piece machinery and should not be subjected to any force beyond what is necessary when inserting it or turning it. If you apply too much pressure, the switch can break and you'll need a professional take it off for repair.
