Abstract

Die Erfindung betrifft einen elektrischen Schalter 1 für Energieversorgungsnetze, insbesondere einen Mittelspannungsschalter, mit schwenkbar gelagertem Schalthebel 6, der mittels eines Betätigungsorgans 71 zwischen einer Schließstellung und einer im Winkel hierzu stehenden Offenstellung schaltbar ist. Der Schalthebel 6 ist wenigstens zweiteilig ausgebildet, wobei zwischen den beiden Teilen 61 und 62 eine Federeinrichtung derart wirkt, daß der Schalthebel 6 in der Schließstellung unter Spannung gerät und die Federkraft an den Lagerstellen 41 und 51 des elektrischen Schalters 1 unter Bildung des elektrischen Kontakts abgestützt ist. Mit einem derartigen elektrischen Schalter 1 lassen sich kurze Schließstrecken und geringe Schließzeiten mit hoher Flächenpressung an den Kontaktstellen verwirklichen. Dabei liegen die Kontaktflächen gut aneinander an und weisen große Flächeninhalte auf. Dadurch können auch hohe Ströme zuverlässig und dauerhaft übertragen werden. Ferner sind nur relativ geringe Betätigungskräfte zum Schalten erforderlich.
