How the Ignition Switch works

The ignition switch is at the core of your car. The ignition switch is the first component you touch to start your vehicle and you shouldn't want it to be damaged. Therefore, it is essential to repair the ignition switch or replaced as soon as there are any signs of trouble.

The basic purpose of the ignition switch is to supply the initial power to other systems in your vehicle, such as accessories, radio and windows. The ignition switch is also responsible for activating the starter motor and engine when the key is turned to the 'on' position.

In order for the ignition system to work, there must be a spark that can ignite the air and fuel in the engine to cause it to start. The ignition coil creates sparks by creating an electromagnetic field that surrounds the rotor as the current flows through. The magnetic field is created as the rotor spins. This causes the ignition spark. This spark then turns 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 transmits a low voltage current to the primary windings as well as the breaker points of your ignition coil. This creates a magnet field that can ignite the spark plugs, and spin the rotor.

When the ignition switch is set to "start", the primary and secondary circuits are both closed. The electrical contact between the distributor cap and rotor terminals breaks as they rotate. This will stop the secondary flow and completes the circuit. This causes the breaker points to close, causing sparks at the spark plug which will then ignite the engine in just a few seconds.

Remember that the ignition switch could be a delicate piece of equipment that shouldn't undergo too much force when it is turned. If you use too excessive force, the switch can break and you'll need an expert to remove it to repair it.
