The invention relates to medicine and can be used for persons with paralysis of upper and lower limbs. The inventive device comprises a signal processing and transmitting module (1), a coordinate unit (2), functional contacts (3), control contacts (4) and an elastic base plate (5) which is symmetrical with respect to a longitudinal axis and is provided with an unbendable projection (6) on the front part thereof. The plate consists of a central circle (7), peripheral circles (8) which are radially spaced away from the central circle, connecting straps (9) mating with the central circle (7) by one end thereof, whilst the other end is coupled with the respective peripheral circle (8). The unbendable projection is made in a shape of an equilateral trapezoid adjacent to the central circle by the larger base thereof and is upwardly bent at about 20 to 60° angle with respect to the plate plane. The signal processing and transmitting module is arranged on the top surface of the central circle of the plate. The coordinate unit is arranged on the lower surface of the central circle. Each functional contact is fixed to the lower surface of the respective peripheral circle. The control contacts are fixed to the lower surface of the unbendable projection. The plate together with operating elements fixed thereto is enveloped with a waterproof film (10). The shape of the film matches the external outlines of the plate with edge allowance (11) and the edge thereof is provided with V-shaped notches (12). Said invention makes it possible to improve the operational characteristics, to simplify the production of the device and to reduce the costs thereof.
