Note: The location and purpose of the switches installed on the vehicle in the instrument panel and in the floor tunnel trim are shown in the chapter "Controls and Instruments".
In the power supply circuit of most of the electrical equipment of the car, voltage comes through the ignition switch. To increase 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 switch housing is attached to the steering column with four special bolts with breakaway heads. At a certain tightening torque, the heads break off, and after that it becomes impossible to unscrew the bolts with keys.
The ignition switch is additionally equipped with a steering shaft locking mechanism. After removing the key from the ignition switch, a spring-loaded latch is released. When attempting to turn the steering wheel, the latch fixes the steering shaft in a certain position.
Switches for the interior light lamp are installed in the doorways on the front and middle pillars. When the door is closed, the switch disconnects the interior light lamp from the ground and the light goes out.
The switch for the reverse lights is installed in the gearbox housing next to the starter. When the reverse gear is engaged, the switch contacts close, supplying voltage to the corresponding lamps in the rear lights.
The brake light switch is mounted under the instrument panel on the brake pedal bracket. When the switch rod is recessed (the brake pedal is released) its contacts are open, and when the rod is extended (the brake pedal is pressed) - closed.
