Common Causes of Faulty Ignition Switches
Ignition switches are the first source of power to your car's accessories as well as the engine. They also determine if the vehicle's keys are in the accessory on or off position.

How the Ignition Switch Works
The ignition switch is the center of your car. The ignition switch is the first thing you touch to start your vehicle and you shouldn't want it to be damaged. This is why it is essential to have your ignition switch replaced or repaired as soon as you begin to notice signs of trouble, like problems getting started or a pulsing motor.
The basic purpose of the ignition switch is to provide the initial energy to other systems within your vehicle, including the radio, accessories and windows. The ignition switch is also responsible for activating the engine and starter motor when the key is turned to the 'on' position.
To allow the ignition system to function there must be spark that can ignite the air and fuel in the engine of your vehicle to begin. The ignition coil creates the spark by creating an electromagnetic field that surrounds the rotor while the current flows through. When the rotor spins the magnetic field grows and the ignition spark is released. The spark will then turn the pistons in your engine, firing them up and getting it to start.
The ignition switch regulates the current of electricity flowing through your primary and secondary circuits. When the switch is set to the "on" position the battery sends low voltage current through the primary coil's windings and then through the breaker points. 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 on "start" the primary and secondary circuits will be shut off. The electrical contact between the terminals for the distributor cap and rotor is broken when they turn. This will stop the secondary flow and completes the circuit. The breaker points close and spark the spark plug. This will start the engine within a matter of seconds.
Make sure to keep in mind that the ignition switch can be a delicate machine that shouldn't undergo excessive force when inserted or turned. If you put excessive pressure, the switch may fail, and you'll need to have a professional take it off for repair.
