Common Causes of Faulty Ignition Switches
The ignition switch is the first source of power for your car's engine and accessories. They also determine if your vehicle's keys are in the accessory, off or on position.

How the Ignition Switch Works
The ignition switch is the heart of your vehicle. It is the first thing you'll touch as you prepare to start your car and the last thing you would want to malfunction. This is why it is crucial to get your ignition switch replaced or repaired when you spot any indications of trouble, for example problems getting started or a pulsing motor.
The primary function of the ignition switch is to provide electricity to other systems of your vehicle like the radio as well as accessories and windows. The ignition switch is 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 can ignite the air and fuel in the engine to cause it to start. The spark is produced by the ignition coil, which creates a magnetic field around the rotor as current passes through it. As the rotor spins the magnetic field grows, and then the ignition spark is released. The spark will change the pistons of your engine, sparking the engine and causing it to start.
The 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 is able to send an unipolar current to the primary windings and breaker points on your ignition coil. This creates an electric field that could spin the rotor, and ignite the spark plugs of your car, which will then fire up the engine.
When the ignition switch is set to'start', the primary and secondary circuits are closed. The electrical connection between the terminals for the distributor cap and rotor break as they rotate. This stops the secondary flow, and completes the circuit. The breaker points will be closed and spark the spark plug. This will ignite the engine within a matter of seconds.
It is important to remember that the ignition switch is a delicate piece of machinery, and should not be put under any force that is too strong when inserting or turning it. If you exert too much force, the switch can fail, and you'll need an expert to take it off to repair it.
