    est porté par un contact fixe (15), avec une extrémité (57) tournée vers le bas, et
    peut être pivotée en éloignement sous l'effet de surintensité pour se désencliqueter du support de pont de contact (20) par son extrémité d'encliquetage formée par le fond de la forme en U (56).
  26. Disjoncteur selon l'une quelconque des revendications précédentes, caractérisé en ce que le tenon d'encliquetage (37) du support de pont de contact (20) est flanqué d'une came de déclenchement (65) rajoutée qui, en pressant la perche de commutation (31) au-delà de la position de mise en marche et de repos du support de pont de contact (20), rend exécutable à la main un déclenchement de disjoncteur par la simulation d'un déclenchement par surintensité de courant.
  27. Disjoncteur selon l'une quelconque des revendications précédentes, caractérisé en ce que la partie de châssis (2) peut être introduite dans la pièce de fermeture (3) avec contacts fixes (14, 15) et pièces fonctionnelles de la cinématique de disjoncteur mis en place, à la manière d'un tiroir, en direction opposée à la direction de mise en marche de la perche de commutation (31), et elle peut être fixée à ladite pièce de fermeture en position d'introduction dans laquelle la pièce de fermeture (3) ferme à la manière d'un couvercle, avec sa paroi de recouvrement, la face ouverte de la partie de châssis (2) et ses subdivisions de paroi, et entoure avec ses parois de flanc des flancs antagonistes de la partie de châssis (2).
