What is an Ignition Switch?
The ignition switch is a crucial component in your vehicle’s electrical system. It controls the power to many of the electrical components, including the starter motor, ignition system, and other accessories. The ignition switch is typically located on the steering column, and it is activated by turning the key.
The ignition switch has several positions, including off, accessory, on, and start. In the off position, the switch shuts off all electrical power to the vehicle. In the accessory position, the switch provides power to some of the electrical components, such as the radio, without turning on the engine. In the on position, the switch provides power to all of the electrical components in the vehicle, but the engine is not yet running. In the start position, the switch provides power to the starter motor, which cranks the engine, and the engine starts running.
