Procedure of solenoidal blocking of switching

When the lever of a choice of transfer is in position “P”, the ignition key is in position “ON” (ВКЛ) and pressing of a pedal of a brake causes electric current receipt to the solenoid. When draught of the solenoid of blocking of switching (or a blocking plate) moves to the solenoid in this condition, the blocking cam (or a latch hairpin) is released that further allows the lever of a choice of transfer to be switched from position “P” in any other position.

Even when the lever of a choice of transfer is in position “P” if the ignition key is in position “LOCK” ("BLOCKING") or “ACC”, or the brake pedal is not pressed, the electric current does not arrive to the solenoid.

In this condition draught of the solenoid of blocking of switching (or the blocking plate) is pushed from the solenoid with effort of a spring, and it obstructs to traffic of a cam of blocking (or latch hairpins). Thus, the button on the lever of a choice of transfer does not work, even by pressing, and the lever of a choice of transfer is not switched.

Тип-1

1 — the lever of a choice of transfer
2 — a blocking cam
3 — draught of the solenoid of blocking of switching
4 — the solenoid of blocking of switching

Тип-2

1 — the lever of a choice of transfer
2 — a latch hairpin
3 — a latch plate
4 — a blocking plate
5 — the solenoid of blocking of switching
