How the Ignition Switch Works
The ignition switch is the center of your vehicle. The ignition switch is the first part you touch to start your vehicle and you shouldn't want it to be damaged. It is therefore crucial to have the ignition switch repaired or replaced as soon as there are any signs of trouble.
The ignition switch's primary function is to provide the power to other systems in your vehicle, including the radio, accessories, and windows. The ignition switch is also responsible for turning on the engine and starter motor when the key is turned to the 'on' position.
In order for the ignition system to work, there must be spark that can ignite the air and fuel in the engine to cause it to start. The ignition coil produces sparks by creating a magnetic field that surrounds the rotor while current passes through. As the rotor spins the magnetic field increases, and then the ignition spark is released. This spark can change the pistons of your engine, which can ignite them and triggering it.
Your ignition switch controls the electrical current that flows through the primary and secondary circuits of your ignition system. When the switch is set to the "on" position the battery will send low voltage current through the primary windings of your ignition coil and then through the points of the breaker. This creates a magnetic field that can ignite spark plugs and turn the rotor.
When the ignition switch is set to "start", the primary and secondary circuits are closed. The electrical connection between distributor cap and rotor terminals is broken as they spin. This stops the secondary flow, and completes the circuit. The breaker points will be closed and spark the spark plug. This will start the engine in a matter of seconds.
Remember that the ignition switch could be a delicate device that shouldn't be subjected to too much force when it is turned. If you apply excessive pressure, the switch could break, and you will require a professional to remove it for repair.
