In the power circuit of most electrical equipment of the car, voltage is supplied through the ignition switch. To improve the anti-theft properties of the car, the switch is combined with the lock, so this device is often called the ignition switch.
The ignition lock housing is attached to the steering column with four special bolts with detachable heads. At a certain tightening torque of the bolts, the heads come off, and after that it becomes impossible to unscrew the bolts with keys.
The ignition lock is additionally equipped with a steering shaft lock mechanism. After removing the key from the ignition lock, the spring-loaded latch is released. When you try to turn the steering wheel, the latch locks the steering shaft in a certain position.
In the doorways on the front and middle pillars, there are switches for the lamp of the ceiling lamp for interior lighting. When the door is closed, the switch opens the connection between the interior light bulb and the «weight» and the lamp goes out.
The reversing light switch is located in the gearbox housing next to the starter. When reverse gear is engaged, the switch contacts are closed, supplying voltage to the corresponding lamps in the rear lights.
The brake light switch is located under the instrument panel on the brake pedal bracket. With recessed switch stem (brake pedal released) its contacts are open, and when the stem is extended (brake pedal pressed) - closed.
