Common Causes of Faulty Ignition Switches
Ignition switches provide the initial power to your car's accessory and engine. They also determine whether your car's keys are in the accessory off or on position.

How the Ignition Switch works
The ignition switch lies at the center of your car. The ignition switch is the first thing you press to start your car and you shouldn't want it to be defective. This is why it's important to have your ignition switch replaced or repaired immediately you spot any indications of trouble, for example problems getting started or a pulsing motor.
The basic function of the ignition switch is to provide the initial power to other systems in your vehicle, such as accessories, radio, and windows. The ignition switch is also responsible for turning on the engine and starter motor when the key is turned to the 'on' position.
To allow the ignition system to work, there must be spark that ignites the air and fuel in your car's engine to start. The ignition coil generates sparks by creating an electromagnetic field that surrounds the rotor as the current moves through. The magnetic field is created when the rotor turns. This generates the ignition spark. The spark will then turn the pistons of your engine, firing them up and allowing it to get to start.
The ignition switch regulates the electrical current flowing through your secondary and primary circuits. When the switch is set to the "on" position, the battery sends low voltage current through the primary windings of your ignition coil and then through the breakers. This creates a magnetic field that can spin the rotor, and spark the spark plugs in your car which then heat up the engine.
When the ignition switch is turned to "start", the primary and secondary circuits will be shut off. As the rotor and distributor cap terminals rotate, the electrical contact between them break and the secondary flow and completes the primary circuit. This allows the breaker points to close, causing a spark at the spark plug which will then fire the engine in just a few seconds.
It is essential to keep in mind that the ignition switch is a delicate piece machinery, and should not be put under any force that is too strong when inserting or turning it. If you put too much pressure, the switch can break and you'll require a professional to remove it to repair.
