Rogetsche Spirale,Roget's Spiral

The Rogetian spiral is a design of a self-breaker which was developed around 1835 by Peter Mark Roget. It consists of a vertically suspended copper wire spiral with a small weight and an iron wire at the lower end. This is dipped into a stainless steel bowl with mercury which is cooled by a water bath. Above the mercury there is a layer of distilled water to suppress the formation of mercury vapour. When a current (approx. 8 amperes) flows in the same direction, parallel conductors are attracted, the spiral contracts slightly and the iron wire is lifted out of the mercury - the current is interrupted. The spiral can relax and makes contact with the mercury again, after which the process is repeated. By changing the weight, the frequency of the spiral can be changed.
Peter Mark Roget (* 18 January 1779 in London; † 12 September 1869 in West Malvern, Worcestershire) was an English doctor and lexicographer [Source:Wikipedia].
Die Rogetsche Spirale ist eine Bauform eines Selbstunterbrechers welche um das Jahr 1835 von Peter Mark Roget entwickelt wurde. Sie besteht aus einer senkrecht aufgehängten Kupferdrahtspirale, an welcher sich am unteren Ende ein kleines Gewicht und ein Eisendraht befindet.Dieser taucht in ein Edelstahlnäpfchen mit Quecksilber welches durch ein Wasserbad gekühlt wird.Über dem Quecksilber befindet sich noch eine Schicht destilliertes Wasser um die Hg-Dampfbildung zu unterdrücken.Da sich bei Stromfluss (ca.8 Ampere) in gleicher Richtung,parallele Leiter anziehen,zieht sich die Spirale etwas zusammen und der Eisendraht wird aus dem Quecksilber gehoben-der Strom ist unterbrochen.Die Spirale kann sich entspannen und nimmt wieder Kontakt zum Quecksilber auf wonach sich der Vorgang wiederholt.Durch ändern des Gewichtes kann die Frequenz der Spirale geändert werden.

Why are there no mercury fumes?

[@xofunkox]

The mercury is covered with distilled water...

[@zohaibhamdule]

@@xofunkox but isnt mercury heavier than water so water should settledown.
