Common Causes of Faulty Ignition Switches
Ignition switches supply the initial power to your car's accessories and engine. They also determine whether your car's keys are in the accessory, on or off position.
Keep spare keys, keepsakes, and other items on a chain apart from the key of your car to avoid ignition switch issues. This will help reduce the mechanical strain on your key cylinder.
How the Ignition Switch works
The ignition switch is located at the center of your car. The ignition switch is the first component you use to start your vehicle, so you don't want it to malfunction. This is why it's crucial to get your ignition switch repaired or replaced as soon as you notice any signs of trouble, such as problems starting or a pulsing engine.
The ignition switch's primary function is to supply power to other systems of your vehicle, including the radio as well as accessories and windows. The ignition switch also turns on the engine and starter motor when the key is in 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 an electric field around the rotor when the current moves through it. As the rotor spins, the magnetic field increases, and then the ignition spark is released. This spark then turns the pistons inside your engine, firing them up and getting it started.
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 is able to send low voltage current through the primary windings of your ignition coil and then through the breakers. This creates a magnetic field that could ignite the spark plugs and spin the rotor.
When the ignition switch is set to "start" the primary and secondary circuits will be shut off. The electrical contact between the distributor cap and rotor terminals breaks when they turn. This stops the secondary flow and completes the circuit. The breaker points close and ignite the spark plug. This will fire the engine in a matter of seconds.
It is essential to keep in mind that the ignition switch is a delicate piece of machinery and should not be subjected to any force beyond what is necessary when inserting it or turning it. If you use too much force, the switch may fail, and you'll need an expert to take it off to repair it.

This could cause the switch to overheat and accelerate internal degradation and wear. Extreme temperaturesHarsh climates may negatively impact the lubricants and materials in the ignition switch. This can speed up its breakdown with time. Moisture and environmental contaminants can also impact the switches' internal components, leading to poor connectivity.
Manufacturing Defects
