Abstract

Eine elektrisch leitende Gelenkanordnung umfaßt einen schwenk­ bar gelagerten Kontakthebel (18) zum Öffnen und Schließen von Schaltkontakten (10, 12). Ein die Schwenkachse (22) des Kon­ takthebels (18) umgebender Gelenkbereich (20) wirkt mit einer ortsfesten Leiteranordnung (24) zusammen, die zwei Teilstücke (26, 28) einer ortsfesten Anschlußschiene (16) und hieraus geformte kontaktgebende Endteile (34, 36) aufweist. Diese übergreifen mit wenigstens drei ebenen Kontaktflächen (32, 38) zangenartig den Gelenkbereich (20) des Kontakthebels (18), Eine Erhöhung der Andruckkraft im Gelenkbereich wird durch parallele Strompfade (A, B) erreicht, die durch eine Abkröpfung wenig­ stens eines der Endteile (36) gegenüber dem anderen Endteil (34) der Teilstücke (26, 28) der Anschlußschiene (16) gebildet sind. An electrically conductive hinge assembly includes a pivot bar mounted contact lever (18) for opening and closing Switch contacts (10, 12). A the pivot axis (22) of the con Articulated area (20) surrounding the clock lever (18) acts with a stationary conductor arrangement (24) together, the two sections (26, 28) a stationary connecting rail (16) and from there has shaped contacting end parts (34, 36). These overlap with at least three flat contact surfaces (32, 38) the joint area (20) of the contact lever (18), pliers-like Increasing the pressure force in the joint area is due to parallel Current paths (A, B) achieved by a little bend least one of the end portions (36) opposite the other end portion (34) of the sections (26, 28) of the connecting rail (16) are formed are.
