Common Causes of Faulty Ignition Switches

Ignition switches supply the initial power to your car's accessories as well as the engine. They also determine if your vehicle's keys are in the accessory, off or on position.

Keep extra keys, keepsakes, and other items on a chain apart from the key of your car to avoid ignition switch issues. This will lessen the mechanical strain on the key cylinder in your car.

How the Ignition Switch Works

The ignition switch is located at the center of your car. The ignition switch is the first part you touch to start your vehicle, so you don't want it to be defective. Therefore, it is essential to get the ignition switch repaired or replaced immediately if there are any signs of trouble.

The primary function of the ignition switch is to provide power to other systems of your vehicle, including the radio, accessories, and windows. The ignition switch also turns on the starter motor and engine when the key is in 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 creates the spark by creating an electric field that surrounds the rotor as the current flows through. As the rotor spins, the magnetic field increases, and then the ignition spark is released. The spark will then turn the pistons in your engine, firing them up and getting it going.

The ignition switch regulates the current of electricity flowing through your secondary and primary circuits. When the switch is in the "on" position, the battery sends 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 your car's spark plugs, which will then fire up the engine.

When the ignition switch is set to'start', the primary and secondary circuits are both closed. The electrical connection between the terminals for the distributor cap and rotor is broken as they spin. 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 crucial to remember that the ignition switch is a delicate piece of machinery, and must not be subjected any force beyond what is necessary when inserting it or turning it. If you apply too much pressure, the switch can break and you'll need a professional remove it for repair.

Certain vehicles have an anti-theft system that requires a key to start the vehicle. The switch will require reprogramming to accept the new key after it's replaced. It's worth noting that this isn't applicable to all vehicles, as older models can be started using any key that works, even if the ignition switch isn't functioning. However, the majority of modern cars require a "chipped" key to start them, so the switch needs to be replaced when the key is replaced.
