10 Misconceptions Your Boss Shares About Car Ignition Switch

Common Causes of Faulty Ignition Switches

Ignition switches supply the initial power to your car's accessory and engine. They also determine if the vehicle's keys are in the accessory off or on position.

How the Ignition Switch works

The ignition switch lies at the center of your car. The ignition switch is the first component you press to start your car, so you don't want it to malfunction.

To allow the ignition system to work there must be a spark that can ignite the air and fuel in the engine of your vehicle to begin. The spark is created by the ignition coil, which creates a magnetic field around the rotor whenever the current flows through it. The magnetic field is created when the rotor turns. This generates the ignition spark. This spark can then turn the pistons in your engine, firing them up and getting it going.

Your ignition switch controls the electrical current that flows through the secondary and primary circuits of your ignition system. When the switch is in the "on" position, the battery sends low voltage current through the primary coil's windings and then through the points of the breaker. This creates an electric field that could spin the rotor and ignite the spark plugs of your car, which will then fire up the engine.

When the ignition switch is set to "start" the primary and secondary circuits are closed. When the distributor and rotor cap terminals rotate, the electrical contact between them break, which stops the secondary flow and then completes the primary circuit. The breaker points will be closed and ignite the spark plug. This will start the engine within seconds.
