15 Reasons You Shouldn't Ignore Car Ignition Switch
Common Causes of Faulty Ignition Switches

The ignition switch is the main source of power for your car's engine and other accessories. They also determine if your vehicle's key is in the on or off position.

Keep extra keys, keepsakes and other items on a chain separate from the car keys to avoid issues with the ignition switch. This will lessen the mechanical stress on the key cylinder.

How the Ignition Switch Works

The ignition switch is the heart of your vehicle. The ignition switch is the first thing you touch to start your vehicle and you shouldn't want it to be defective. It is therefore important to have the ignition switch repaired or replaced when you notice any signs of trouble.

The primary function of the ignition switch is to supply electricity to other systems of your vehicle including the radio as well as 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 needs to function because it needs sparks to ignite the air and fuel in your car to begin. The spark is produced by the ignition coil which creates an electric field around the rotor when the current flows through it. When the rotor spins the magnetic field builds up, and then the ignition spark is released. This spark can then turn the pistons in your engine, firing them up and getting it going.

The ignition switch controls the electrical current running through your primary and secondary circuits. When the switch is in the "on" position, the battery sends a low voltage current to the primary windings and breaker points of your ignition coil. This creates a magnet field that can ignite spark plugs, and spin the rotor.

When the ignition switch is turned on "start" the primary and secondary circuits will be shut down. When the distributor and rotor cap terminals rotate, the electrical contact between them break, which stops the secondary flow and then completes the primary circuit. The breaker points are able to close and produce a spark at the spark plug which will then ignite the engine in a matter of seconds.

Make sure to keep in mind that the ignition switch could be a delicate device that should not undergo extreme force when it is inserted or turned. If you use too much force, the switch could fail, and you'll need an expert to take it off for repairs.

This can cause the ignition switch to overheat, which can accelerate its internal wear and degradation. Extreme temperatures and harsh climates can negatively affect the materials and lubricants used in the ignition switch, speeding up its degrading process over time. The environmental contaminants and moisture may affect the switches' internal components, leading to poor connectivity.
