FIELD: physics, radio engineering.
SUBSTANCE: invention is related to the field of radio engineering and may be used in computer means, systems of automation and control, radio communication systems, and also in other fields of science and engineering. Invention is based on the task of energy-information-protected keyboard development, in which higher screening degree brings better energy-information protection, and also provides for lower keyboard height due to elimination of volume buttons comprising contact pairs and installed on wire board, and higher stability of key stems under mechanical action of operator's hand on key by introduction of the second guide in the upper part of stem.
EFFECT: development of energy-information-protected keyboard.
