10 Things Everyone Hates About Car Ignition Switch
Common Causes of Faulty Ignition Switches
Ignition switches are the first source of power to your car's accessories and engine. They also determine if the key in your car is in the on, accessory, or off position.
To avoid problems with your ignition switch, keep extra keys and keepsakes on an additional chain separate that is not connected to the car's keys. This will lessen the mechanical stress on the cylinder of your key.
How the Ignition Switch Works
The ignition switch is at the core of your vehicle. It's the first thing you do when getting ready to start your car and the last thing you would want to malfunction. This is why it's essential to have your ignition switch replaced or repaired when you notice any signs of trouble, for example problems starting or a pulsing sound.
The primary function of the ignition switch is to provide electricity to other systems of your vehicle like the radio as well as accessories and windows. The ignition switch is responsible for activating the starter motor and engine when the key is turned to the "on position.
In order for the ignition system to function there must be spark that can ignite the air and fuel in the engine to cause it to start. The ignition coil creates the spark by creating a magnetic field that surrounds the rotor while the current moves through. The magnetic field is created as the rotor spins. This creates the ignition spark. The spark will then turn the pistons of your engine, firing them up and getting the engine 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 sends low voltage current to the primary windings and breaker points of your ignition coil. This creates an electric field that could spin the rotor and ignite your car's spark plugs which then heat up the engine.
When the ignition switch is turned to "start" the primary and secondary circuits will be shut off. When the distributor and rotor cap terminals rotate, the electrical contact between them breaks and the secondary flow and closes the primary circuit. This allows the breaker points to close and create sparks at the spark plug which will then fire the engine in a matter of seconds.
Be aware that the ignition switch can be a delicate device that shouldn't be subjected to excessive force when inserted or turned. If you exert too much force, the switch may fail, and you'll need an expert to remove it to make repairs.
