How the Ignition Switch works
The ignition switch is the heart of your vehicle. It is the first thing you'll touch when getting ready to start your car and the last thing you would want to be damaged. It is therefore important to repair the ignition switch or replaced when you notice any indications of trouble.
The primary function of the ignition switch is to supply power to other systems of your vehicle like the radio, accessories, and windows. The ignition switch also turns on the starter motor and engine when the key is in the "on" position.
To allow the ignition system to work it must have spark that ignites the air and fuel inside the engine to cause it to start. The ignition coil produces the spark by creating an electric field that surrounds the rotor as the current moves through. The magnetic field is created when the rotor rotates. This creates the ignition spark. This spark could change the pistons of your engine, igniting the engine and causing it to start.
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 sends an unipolar current to the primary windings and breaker points on your ignition coil. This creates a magnetic field that could ignite the spark plugs, and spin the rotor.
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 connection between them is broken, which stops the secondary flow and completes the primary circuit. This allows the breaker points to close, causing a spark at the spark plug which will then fire the engine within a matter of seconds.
