Electric transfer case switching drive for four-wheel drive vehicles of the Niva 4x4 2121, 21213, 21214, 2131 and their modifications. The set consists of two mechanisms, each individually driven by an electric motor. The mechanisms are installed and fixed to the regular places of the transfer case housing instead of the diagnostic cover and the cover of the lock-on alarm sensor attachment. The installation of mechanisms does not require significant changes to the design of standard parts and components of the transfer case. Switching modes of the transfer case is carried out by switches located on the instrument panel.
