What is an Ignition Switch and its Function?

An ignition switch is an electrical component of a vehicles ignition system. It is responsible for energizing the electrical system in order to start the engine. The switch also controls the flow of current from the battery to other parts of the ignition system such as the starter motor and distributor. In some vehicles, the ignition switch serves several other functions such as controlling power windows, radio, lights, and other accessories.

What Does It Do?

The main purpose of an ignition switch is to control the flow of electricity from the battery to all components that need it to operate. When you turn your key in the ignition, it activates a series of events which allow fuel to be injected into the engine and spark plugs to ignite it. The switch also helps ensure that all components in your car are working correctly when they receive power from the battery.

How Does It Work?

When you turn your key in the ignition, it sends a signal through a series of electrical pathways that activate several switches within your cars wiring harness. These switches then send power to various components such as starter motors, alternators, fuel injectors, spark plugs and more. If any component fails or does not receive enough power from these switches, then your vehicle will not start or run properly.
