What is a GM Column Ignition Switch?

The GM column ignition switch is a key component of the electrical system in many General Motors vehicles. This switch is responsible for controlling the flow of electricity to the engine and various other parts of the vehicle. The column ignition switch is typically located at the base of the steering column, and is activated by turning the vehicle key.

One of the key benefits of the GM column ignition switch is that it provides a consistent and reliable source of power to the engine, even in harsh conditions. This helps to ensure that your vehicle is always running smoothly, no matter what the driving conditions may be.

How Does a GM Column Ignition Switch Work?

The GM column ignition switch works by directing electrical current from the vehicle’s battery to the starter motor, fuel system, and other components. When the vehicle key is turned, the switch sends a signal to the starter motor to engage, allowing the engine to begin running. From there, the switch directs current to other parts of the vehicle as needed.

Most GM column ignition switches also include additional features, such as a steering lock or anti-theft system. These features are designed to help prevent unauthorized use of the vehicle, and can provide an additional layer of security.
