Series circuit of a number of electric current consumption units (2) connected in series, such as lamps for example, or groups of such units, each consumption unit having a by-pass circuit, which will be activated and divert the current in case of failure or breaking down of an accompanying consumption unit during current transporting operation, so that the current going through the series circuit (1) will not be interrupted, in which each by-pass circuit has at least one switch (4) which is switched on by the occurring voltage rise on cut-off of the current through its consumption unit (2) and which, regardless of the current intensity through the series circuit (1), is kept in switched-on condition by the hold-function of a memory element (5), and which switch can only be switched back by an external signal (8). |
