GERMAN The invention relates to switching from parallel connection to series connection and vice versa of three electrical consumers, such as those used, for example, as a power-saving circuit for lighting purposes. There is already an economy circuit for three incandescent lamps in which the three incandescent lamps are used in parallel or can be connected in series. A disadvantage of this known economy circuit is in it see that a special, not commercially known roller switch must be used for this, the also gives rise to disturbances due to considerable spark formation. In contrast, the invention enables a power-saving circuit, for example, for three incandescent lamps in easiest way. The invention consists in that the parallel connection, based on the series connection of three electrical Consumer, is effected by the fact that the middle of the three consumers by means of a conventional double-pole on-off switch is cross-connected to the voltage source. In »on« switch position of the double-pole switch, for example, every single one of the three light bulbs is full Operating voltage, and thus the three light bulbs get their usual light intensity. In the "off" switch position all three bulbs are connected in series. Accordingly, each incandescent lamp receives only a third of the operating voltage, whereby the watt consumption goes back to about the 7th part. the Series connection naturally has incandescent lamps of the same type, i.e. incandescent lamps with the same voltage drop a prerequisite. When using three incandescent lamps of 25 watts each, the parallel connection leads to a total expenditure of 75 watts, while switching over to a series connection of the incandescent lamps the necessary effort by determining a watt meter goes back to 11 watts and the Luminous intensity decreases even more strongly according to the lowered filament temperature. These Luminosity is just enough to still be able to recognize people and to distinguish objects from one another. This economy circuit is z. B. for emergency lighting, for night lighting in railroad cars as well as for air protection and the like are particularly suitable, since the weak light does not linger if the light is negligently darkened outside penetrates. In the drawing, an embodiment of the invention is shown, and it shows the figure Circuit diagram of the power-saving circuit. Switching from parallel connection

Bremen, Vegesacker Str. 86 Marie Kuckuck, née Mahler, Bremen,
has been named as the inventor 1 with the power line serving as a voltage source is indicated, from which the supply lines 2, 3 are branched. Between the two supply lines 2, 3, the lead-through line 4 is provided, which connects the lighting points 5, 6 and 7 in series. In addition, the supply lines 2, 3 are each connected to a clamping pole 8, 9 of the two-pole on-off switch, while the connecting lines 10, 11 shown crossed are connected to sections of the feed-through line 4. Here, the line 10 is connected once to the clamping pole 13 and the opposite end to the line 4 between the lamps 5, 6. The line 11, on the other hand, is connected to the clamping pole 12, the opposite end to the line 4, between the lamps 6, 7 . The power-saving circuit is switched off by a main switch (not shown).
