Locking device for locking arrangement of adapter for fastening e.g. switching device, has level part that is pivotable around pivot axis from adapter, where pivot axis runs perpendicular to surface to yield section from gradated spiral

摘要

The device has a level part (3) pivotable around a pivot axis (32) from an adapter, where the level part has a step-like arranged level with level section surfaces (33) for locking system at a lower side of a feeder rail. The axis runs perpendicular to the surface to yield a section from a gradated spiral. The surfaces run parallel to each other to the system at the rail, where the surfaces at a side facing the axis have a larger depth. The surface of a lowest level has a section with a parallel delimitation edge (34) that is turned away the axis and is rounded off.
