Common Causes of Faulty Ignition Switches

How the Ignition Switch Works
The ignition switch is at the core of your vehicle. It's the first thing you'll touch when you are getting ready to start your car and the last thing you would want to malfunction. This is why it is essential to have your ignition switch repaired or replaced as soon as you notice any signs of trouble, for example difficulty starting or a pulsing sound.
The basic function of the ignition switch is to provide the initial energy to other systems within your vehicle, including radio, accessories, 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 has to function because it needs sparks to ignite the air and fuel inside your car for it to start. The spark is created by the ignition coil, which creates an electric field around the rotor when the current flows through it. The magnetic field is created as the rotor turns. This creates the ignition spark. This spark can then turn the pistons of your engine, igniting them up and getting the engine started.
The ignition switch controls the electrical current that runs through the primary and secondary circuits of your ignition system. 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 an electric field that could spin the rotor and spark the spark plugs in your car that then start firing up the engine.
When the ignition switch is set to "start" the primary and secondary circuits are closed. The electrical contact between the terminals of the distributor cap and the rotor is broken when they turn. This stops the secondary flow, and completes the circuit. This allows the breaker points to close, causing sparks at the spark plug which then ignites the engine in a matter of seconds.
Remember that the ignition switch can be a delicate device that shouldn't undergo extreme force when it is inserted or turned. If you use too excessive force, the switch can fail and you'll require a professional to remove it to make repairs.
