(FR) MICROCONTACT DE COMMUTATION
Abstract
(DE)
Die Erfindung betrifft einen mechanisch schließenden elektrischen Mikroschalterkontakt (1) mit zwei elektrisch leitenden Kontaktelementen (7, 8), die zur Kontaktierung mit jeweilingen Kontaktflächen miteinander in Berührung treten. Erfindungsgemäß besteht nun mindestens eine der Kontaktflächen zumindest teilweise aus hochdotiertem leitfähigem Diamant, Siliziumcarbid, Galiumnitrid, Bornitrid, Aluminium-Galiumnitrid und/oder Aluminiumnitrid.
(EN)
The invention relates to a mechanically closing, electric microswitching contact (1) comprising two electrically conductive contact elements (7, 8) whose respective contact surfaces come into contact with one another. According to the invention, at least one of the contact surfaces is at least partially comprised of highly-doped conductive diamond, silicon carbide, gallium nitride, boron nitride, aluminum gallium nitride, and/or aluminum nitride.
(FR)
L'invention concerne un microcontact de commutation électrique (1) à fermeture mécanique, qui comprend deux éléments de contact (7, 8) électroconducteurs qui entrent en contact l'un avec l'autre pour établir le contact avec des surfaces de contact respectives. Selon l'invention, maintenant au moins une des surfaces de contact est constituée, au moins partiellement, de diamant conducteur hautement dopé, de carbure de silicium, de nitrure de gallium, de nitrure de bore, de nitrure d'aluminium et de gallium et/ou de nitrure d'aluminium.
