Abstract

L'invention porte sur des conducteurs (13) qui sont enfouis en exerçant une pression dans un corps (12) constitué d'une composition et préparé par pétrissage de 35 à 60 % en volume d'une charge en poudre conductrice avec un composant polymère cristallin de sorte que les conducteurs (13) soient partiellement dégagés de la surface du corps constitué de la composition. Des électrodes de platine (14A, 14B) sont formées par placage sur le corps (12) constitué de la composition. La charge conductrice en poudre contient au moins un type de TiC, WC, W¿2?C, ZrC, VC, NbC, TaC et Mo¿2?C. L'adhésion entre la composition à coefficient de température positif et les électrodes est bonne, et la résistance au contact entre elles, faible. Ce dispositif à coefficient de température positif présente une excellente stabilité contre les applications répétées de courant.
