Common Causes of Faulty Ignition Switches

How the Ignition Switch Works
The ignition switch is at the core of your vehicle. The ignition switch is the first part you touch to start your vehicle, so you don't want it to be damaged. It is therefore important to get the ignition switch repaired or changed immediately if there are any signs of trouble.
The ignition switch's primary function is to supply the power to other systems in your vehicle like the radio as well as accessories and windows. 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 requires sparks to ignite fuel and air inside your car for it to start. The spark is generated by the ignition coil which creates an electrical field around the rotor when the current flows through it. The magnetic field is created when the rotor spins. This creates the ignition spark. The spark will then turn the pistons of your engine, firing them up and allowing it to get going.
The ignition switch controls electrical current that flows through the secondary and primary circuits of your ignition system. When the switch is in the "on" position, the battery is able to send low voltage current through the primary coil's windings and then through the breakers. This creates magnetic fields that 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 both closed. The electrical contact between the terminals of the distributor cap and the rotor break as they rotate. This will stop the secondary flow and completes the circuit. The breaker points close and spark the spark plug. This will fire the engine within a matter of seconds.
Make sure to keep in mind that the ignition switch could be a delicate machine that should not undergo extreme force when it is inserted or turned. If you apply excessive pressure, the switch may break, and you will need a professional remove it for repair.
