In the Chevy Lumina, the ignition switch is separate from the key lock cylinder mounted in the steering column behind the steering wheel. In the Lumina, the ignition switch is mounted low on the steering column and actuated by a gear and rod mechanism attached to the end of the key lock cylinder. The heavy duty contacts in the ignition switch control the supply of electrical energy to the starting, charging and accessory systems in the car.
