Frequently Asked Questions
What are ignition switches?
An ignition switch (also known as a starter switch) activates a vehicle's main electrical system, providing the necessary power to engage a vehicle's ignition system and accessories, such as the radio, power windows, wipers, and signals. When the switch is turned to the off position, it deactivates the electrical system and turns the vehicle off.
How do ignition switches work?
An ignition switch engages a vehicle's main electrical system, allowing voltage to flow from the vehicle's battery to the ignition system. Typically, keyed ignition switches feature a lock cylinder, while push-button ignition switches use a button and remote control system to communicate with a vehicle's computer. Ignition switches can be simple 2-position on/off
