A device for a controlled electrostatic discharge in persons consists of two electrically non-conductive elements (1) mutually spaced by at least one spring (2) and arranged in a housing (3), wherein at least one element (1) is arranged in the housing (3) in a way to come closer parallel to a second element (1) when force is exerted on it from the outside, wherein electric pins (5) are arranged on adjacent surfaces (4) of both elements (1) and arranged on each surface (4) at a mutual distance (a) and the two surfaces (4) are arranged at a mutual distance (b) and simultaneously the rows of pins (5) on one and the second element (1) are offset, so that the pins (5) of one row lie in the middle of the distance (a) and both rows of pins (5) are spaced from each other by a distance (b), wherein the first pin (5) in the row on one element (1) and the last pin (5) in the row on the second element (1) are connected in series to a discharge electric circuit comprising a section (6) on the element (1), pins (5) and a grounding conductor (7). An air gap (c) defining the breakdown strength of the air is a sum of diagonal distances (d) between the closest pins (5) of the first and the second row of pins (5).
