Abstract

Un contacteur fin (142) comporte une couche inférieure (144) et une couche supérieure (160). Des premier et deuxième conducteurs (148, 162) situés sur la couche inférieure (144) forment deux chemins conducteurs séparés, une tension étant appliquée à ces conducteurs (148, 162). La couche supérieure (160) comprend un conducteur de masse (172). Des intercalaires (178) sont positionnés entre les couches supérieure et inférieure (160, 144). Lorsque des forces sont appliquées de l'extérieur, les intercalaires (178) s'affaissent et le conducteur de masse (172) touche les premier et deuxième conducteurs (148, 162) et établit un chemin conducteur entre eux.
