What is a kill switch in a car?

A kill switch in a car is a device that is designed to stop the engine of the car from running when activated. This can be done manually or automatically, depending on the type of kill switch installed. Kill switches are commonly used as an anti-theft device to prevent unauthorized individuals from starting and driving a car away. They are also used in drag racing cars and other high-performance vehicles to quickly disable the engine in case of an emergency or accident. Kill switches can be wired into various parts of the car, including the ignition system, fuel pump, or other critical components. In many cases, they are hidden and require a specific combination of actions or inputs to activate, making them more difficult for thieves to bypass.
