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, on or off position. Keep spare keys, keepsakes and other items on a chain apart from the car keys to avoid issues with the ignition switch. This will help reduce the stress on your car's key cylinder. How the Ignition Switch works The ignition switch is the heart of your vehicle. The ignition switch is the first thing you use to start your vehicle, so you don't want it to malfunction. It is therefore crucial to repair the ignition switch or changed as soon as there are any signs of trouble. The primary 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 also turns on the engine and starter motor 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 inside the engine to cause it to start. The spark is generated by the ignition coil, which creates an electric field around the rotor as current passes through it. The magnetic field is created when the rotor spins. This causes the ignition spark. The spark will then turn the pistons inside your engine, igniting them up and allowing it to get started. The ignition switch regulates the electrical current flowing through your secondary and primary circuits. When the switch is in the “on” position the battery is able to send low voltage current to the primary windings and breaker points of your ignition coil. This creates magnetic fields that 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 both closed. As the rotor and distributor cap terminals rotate, the electrical contact between them is broken and stops the secondary flow and completes the primary circuit. The breaker points will be closed and spark the spark plug. This will fire the engine within seconds. Make sure to keep in mind that the ignition switch can be a delicate piece of equipment that shouldn't be subjected to excessive force when inserted or turned. If you exert too excessive force, the switch may fail, and you'll need a professional to remove it to repair it.

It's worth noting that this doesn't apply to all vehicles, since even older models can be started with an ordinary key if the ignition switch isn't functioning.
