Procedure of solenoidal blocking of switching

When the lever of the choice of transfer is in situation "P", the ignition key is in the provision of "ON" ("VKL") and pressing of a pedal of a brake causes receipt of electric current to the solenoid. When draft of the solenoid of blocking of switching (or a blocking plate) moves to the solenoid in this state, the blocking cam (or a latch hairpin) is released that allows the lever of the choice of transfer to switch further from situation "P" in any other situation.

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

In this state draft of the solenoid of blocking of switching (or a blocking plate) is pushed from the solenoid with effort of a spring, and it obstructs the traffic of a cam of blocking (or latch hairpins). Thus, the button does not work at the lever of the choice of transfer, even when pressing, and the lever of the choice of transfer does not switch.

Type-1

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

Type-2

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