Abstract: An electrical contact assembly, in which a first and a second contact element are electrically insulated from one another by at least one insulation element or an electrically insulating coating. In both contact elements, a through hole is formed, into each a pin can be introduced. On the first contact element and/or the first pin and the inner lateral surface of the second contact element and/or the outer lateral surface of the second pin, a groove-shaped depression is formed, having at least one annular spring element inserted which is formed from an electrically conductive and elastically deformable material, it is geometrically formed and dimensioned such that the wall facing radially outwards and/or radially inwards acts with a pressure force against the surface of a pin and the surface of the contact elements in a groove-shaped depression. The contact elements and pins are connected to an electrical voltage source.
