Patentanspruch :Claim:Flüssigkeitsschalter mit leitender Schaltflüssigkeit, bei welchem bei der Stromunterbrechung
zwischen 'die sich trennenden Kontakte
ein zunehmender Widerstand, gebildet durch die leitende Schaltflüssigkeit, in den abzuschaltenden Stromkreis eingeschaltet
wird, dadurch gekennzeichnet, daß an dem festen und dem beweglichen Kontakt
eine Anzahl rohrförmiger Metallelektroden so angeordnet sind, daß sie bei eingeschaltetem Schalter ineinandergeschoben
sind, sich aber nicht berühren und beim Ausschalten des Schalters mit zunehmender
Kontaktentfernung auseinandergeschoben werden, so daß bei der Stromunterbrechung
der Widerstand nach dem Öffnen des Stromkreises an den Hauptkontakten zwischen den metallenen Rohrelektroden
zunächst noch gering bleibt und erst bei weiterer Trennung der Kontakte allmählich zunimmt. goLiquid switch with conductive switching liquid, in which case the power is interrupted
between 'the separating contacts
an increasing resistance, formed by the conductive switching fluid, switched into the circuit to be switched off
is, characterized in that on the fixed and the movable contact
a number of tubular metal electrodes are arranged so that they slide into one another when the switch is on
are, but do not touch and when turning off the switch with increasing
Contact distance are pushed apart, so that when the power is interrupted
the resistance after opening the circuit at the main contacts between the metal tube electrodes
initially remains low and only gradually increases when the contacts are further separated. go

Circuit which, under the influence of switching voltages, passes on a voltage of any polarity applied to its input terminal from its output terminal, especially for equalizing transmitters for telegraphic characters
Slider switch, the movable contact piece provided with detents for the contact springs under spring action, can be moved in the direction of the switch axis on the switch bolt
