Ignition Starter Switches
The ignition system is the primary system for the start up of the vehicle. It is like a mini distributor for the initial systems of the car. It gets the voltage going so that the combustion can start. After the engine starts, other systems take over the initial job of the ignition system. The ignition start switch is like the gear box for all these primary operations. It usually has five positions: start, run, accessories, lock, and off. The start position is spring loaded and signals the draw from the battery that gets amplified and eventually results in the starting of the engine. When the engine starts, the switch automatically goes to run position until the key is turned to a different position. Most vehicle drivers use the accessories position less frequently. It is designed to supply power to accessories in the car like the radio or the lights when the engine is not running.
