How the Ignition Switch Works

The ignition switch is at the core of your car. The ignition switch is the first component you press to start your car, so you don't want it to malfunction. It is therefore important to have the ignition switch repaired or changed immediately if there are any indications of trouble.

The ignition switch's primary function is to supply electricity to other systems of your vehicle including the radio as well as accessories and windows. The ignition switch also activates the starter motor and engine 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 in the engine of your vehicle to begin. The spark is produced by the ignition coil which creates an electrical field around the rotor when the current flows through it. When the rotor spins the magnetic field grows, and then the ignition spark is released. This spark can then turn the pistons in your engine, firing them up and allowing it to get started.

The ignition switch controls the electrical current running through your primary and secondary circuits. When the switch is in the "on" position, the battery sends low voltage current to the primary windings as well as the breaker points of your ignition coil. This creates a magnetic field that can ignite the spark plugs and spin the rotor.

When the ignition switch is turned to "start" the primary and secondary circuits will be closed. The electrical connection between distributor cap and rotor terminals break when they turn. This stops the secondary flow and completes the circuit. This causes the breaker points to close, causing sparks at the spark plug, which will then fire the engine in just a few seconds.
