Abstract
An electrochemical time switching device comprising a hollow body (1). The hollow body (1) is filled with a liquid electrolyte (12), in which a disintegrable anode (11) and a cathode (8) are arranged, between which a charge flows through the electrolyte (12) when a voltage is applied between the anode connection (6) and the cathode connection (7). An elastic sleeve (9) is arranged in the hollow body (1) between the anode connection (6) and the anode (11) and this sleeve encloses an electrical lead-in wire (10) interconnecting the anode connection (6) and the anode (11). The cross-section of the lead-in wire (10) is smaller than the cross-section of the anode (11) and its length is smaller than the length of the relieved sleeve (9).
