Variable transparent cabinet, is designed in the form of an insulating panel with a standard border (90) being filled with a moisture absorbtion substance (91) and connected to the light polarizing panels (P) and (A) over a primary substance (92) and a secondary substance (93). Between the polarizers (P) and (A) there is at least one movable biaxially directed panel (R) which, due to the rotation under the angle the value of which is less than 46 degrees, leads to the change in the optical transparency of the screen (To), the given value depends exclusively on the actual position of the panel (R). Moving of the external ferromagnetic plate (Q) in a housing (W) due to the impact of a permanent magnetic field induces identical moving of internal ferromagnetic plate (L), in a housing (M) which moves, a thread (K) being drawn through a tubular guide (J) in its ends connected onto the internal ferromagnetic plate (L) and connected to tha panel (R), thus causing the rotation of the panel (R) which has in each characteristic periferral referent point, distancers (99) on both sides, that provide a mechanical stability thereto during its movement and prevent surface friction against the polarizers (P) and (A). Variable transparent cabinet provides efficient protection of privacy from outside views, protection from external temperature, accoustic and mechanical influences from the environment, protection from light, particularly from the sunlight and solar energy, it has a reliable and permanent exploitation along with using standard procedures for manufacture, assembling, control, maintenance and disassembling, and repair thereof.
