 gehäuse und der andere mit einem in diesem isoliert angeordneten Kontakt verbunden, wobei die als Brücke dienende Membran isoliert im Metallgehäuse gelagert wird. Diese Isolierung wird in einfachster Weise dadurch erzielt, dass die Auflagefläche und   Aussenkante   der Membran mit einer Isolierschicht aus streichbarem, erhärtendem Material wie z. B. Lack, versehen wird. Zur grösseren Sicherheit der Isolierung kann auch noch der für, die Auflage der Membran dienende Rand der Membrankapsel mit einer ähnlichen Isolierschicht überzogen werden. 



   Die Zeichnung veranschaulicht den Erfindungsgegenstand in Fig. 1 in Draufsicht bei abgenommener Membran und in Fig. 2 in Schnittansicht. 



   Die mit den Gesenken für die Kohlekömer ausgebildete Elektrode ist in zwei Hälften 1

 housing and the other connected to a contact arranged in this isolated manner, the membrane serving as a bridge being stored in an isolated manner in the metal housing. This isolation is achieved in the simplest way that the support surface and outer edge of the membrane with an insulating layer of paintable, hardening material such as. B. paint is provided. For greater security of the insulation, the edge of the membrane capsule, which is used to support the membrane, can also be covered with a similar insulating layer.



   The drawing illustrates the subject matter of the invention in FIG. 1 in a plan view with the membrane removed and in FIG. 2 in a sectional view.



   The electrode formed with the dies for the carbon grains is in two halves 1
