Abstract

Un appareil comprend un contact constitué d'éléments micro-électromécaniques, les éléments micro-électromécaniques comprenant une chambre étanche contenant un élément diélectrique, et des conducteurs dans la chambre étanche. Les conducteurs sont disposés de manière à ce que l'application d'une tension supérieure à une tension prédéterminée à au moins un des conducteurs cause la dégradation par ionisation de l'élément diélectrique pour former un parcours conducteur de l'électricité entre les conducteurs. Dans une autre réalisation, un contact comprend un émetteur d'électrons à nanotube ou un émetteur d'électrons à isotope radioactif.
