Abstract
A switching apparatus for an electrical switching device is disclosed, in particular an electrical circuit breaker, for safeguarding at least two poles. A tripping element is included for each pole, supported moveably between a rest position and a tripping position. A common switching frame, movable between a pre-tension position and a switching position, is actively connected for force transmission to frame sections of the at least two tripping elements for the movement of the switching frame into the switching position upon movement of the tripping element into the tripping position. At least one spring element is embodied to apply force to the frame sections of the at least two tripping elements in the direction of the rest position of the at least two tripping elements.
