Description

Die Erfindung betrifft eine Wasserwaage, bei der die Libellen, sowohl die senkrechte wie auch die waagerechte, von jeweils zugeordneten Glühbirnen beleuchtet werden. Die Beleuchtung der Libellen über einen gemeinsamen Schalter ist bekannt. Bei dieser bekannten Wasserwaage leuchten infolge der gemeinsamen Schaltung immer beide Glühbirnen zu gleicher Zeit auf. Bei dem Gegenstand der Erfindung ist für jede Libellenbeleuchtung ein zuständiger Schalter angeordnet, so daß jede Libelle für sich nach Bedarf beleuchtet wird. Jede einzelne Glühbirne hat ihre eigene Stromquelle und ihren eigenen Stromkreis. The invention relates to a spirit level in which the dragonflies, both the vertical as well as the horizontal, illuminated by respectively assigned light bulbs will. The lighting of the dragonflies via a common switch is known. With this known spirit level always light up due to the common circuit both lightbulbs on at the same time. The subject of the invention is for each dragonfly lighting a relevant switch arranged so that each dragonfly is illuminated for itself as required. Each individual light bulb has its own power source and their own circuit.

In der Zeichnung ist der Erfindungsgegenstand schematisch dargestellt. Es bedeuten I die Batterien, 2 und 2' die Anschlüsse, 3 und 3' die beiden getrennt zu betätigenden Schalter, 4 und 4' die Glühbirnen, 5 und 5' die beiden Libellen, 6 die Verbindungsdrähte. The subject of the invention is shown schematically in the drawing. I mean the batteries, 2 and 2 'the connections, 3 and 3' the two separately switch to be operated, 4 and 4 'the lightbulbs, 5 and 5' the two dragonflies, 6 the connecting wires.

Da in allen Gebrauchsfällen nur eine Libelle benutzt wird, ist durch die getrennte Schaltung eine wesentliche Stromersparnis gewährleistet. Since only one level is used in all cases of use, it is through the separate circuit ensures significant power savings.
