A pull-out frame for a switching device with a threaded spindle and a tripping device which can be actuated by a tool provided for actuating the threaded spindle. In the switching device, a coupling member is arranged which transmits the motion of the tripping device of the pull-out frame to a tripping device of the switching meachanism of the switching device. A latching device controlled by the positioning drive makes provision that the tripping device is released only in the course of the travel motion of the switching device for resetting.
