摘要： Electrode arrangement with liquid-metal electrode of controllable surface, comprising a liquid-metal reservoir, a capillary connected thereto through a controllable valve and contact means being in electric contact with the liquid-metal in the capillary. According to the invention at least one section of the capillary is formed within a metal body not reacting chemically with the liquid-metal, said metal body constituting the contact means. Preferably, the metal body is formed so that an elastic closing element of the valve fits to a surface of the metal body surrounding an opening of the capillary section formed therein.
