Abstract

Die Erfindung betrifft Niederspannungsschalter mit Sperrhebel, die als Trenn- oder als Schutzschalter ausgeführt sein können und bei denen der Sperrhebel die Überführung des Betätigungshandgriffes in die Ausschaltestellung verhindert, wenn die Kontakte des Schalters blockiert sind. The invention relates to low-voltage switches with locking levers can be designed as a disconnector or as a circuit breaker and at which the locking lever the transfer of the operating handle in the off position prevents when the contacts of the switch are blocked.

Der Sperrhebel ist als Sperrlasche (11) ausgebildet, die hinter der oberen Kniegelenklasche (6) in gleicher Ebene wie die Kniegelenk­ lasche angeordnet ist, derart, daß ein Ende der Sperrlasche (11) orts­ fest drehbar am Schloßhalter (10) gelagert und das andere Ende mit dem Antriebshebel (13) gekoppelt ist, und das mit dem Antriebs­ hebel (13) gekoppelte Ende der Sperrlasche (11) während des Aus­ schaltens an die obere Kniegelenklasche (6) zum Anliegen kommt. The locking lever is designed as a locking tab (11) behind the upper knee joint tab (6) in the same plane as the knee joint tab is arranged such that one end of the locking tab (11) in place firmly rotatably mounted on the lock holder (10) and the other end with the drive lever (13) is coupled, and that with the drive lever (13) coupled end of the locking tab (11) during the off switches to the upper knee joint tab (6).
