Common Causes of Faulty Ignition Switches Ignition switches are the first source of power to your car's accessories as well as the engine. They also determine if the vehicle's keys are in the accessory, on or off position. To avoid problems with your ignition switch, keep extra keys and keepsakes on a separate chain from the car's key. This will help reduce the stress on the key cylinder. How the Ignition Switch works The ignition switch lies at the heart of your vehicle. It's the first thing you do when you are getting ready to start your car, and the last thing you want to be faulty. This is why it is essential to have your ignition switch replaced or repaired as soon as you spot any indications of trouble, for example difficulties starting or a pulsing engine. The primary function of the ignition switch is to provide electricity to other systems of your vehicle including the radio, 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 needs to function because it requires sparks to ignite fuel and air inside your car for it to start. The ignition coil produces sparks by creating an electromagnetic field that surrounds the rotor while current passes through. The magnetic field is created when the rotor turns. This creates the ignition spark. The spark will rotate the pistons of your engine, which can ignite them and starting it. Your 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 low voltage current to the primary windings and breaker points on your ignition coil. This creates a magnet field that can ignite spark plugs and turn the rotor. When the ignition switch is turned to “start”, the primary and secondary circuits will be closed. The electrical connection between terminals of the distributor cap and the rotor breaks as they spin. This will stop the secondary flow and completes the circuit. This allows the breaker points to close, causing sparks at the spark plug, which will then fire the engine in just a few seconds. It is essential to keep in mind that the ignition switch is a delicate piece of machinery that must not be subjected any force that is too strong when inserting or turning it. If you apply too much force, the switch may break and you'll need an expert to remove it for repairs.
