Abstract

The invention relates to a mechanical locking device for two mechanically or electromechanically operated switchgears, arranged side-by-side, for preventing the simultaneous switching on of both contactors, a slide being coupled to each contactor and each slide acting on a locking device which is arranged such that it can move between the two slides, and the locking device being designed as a angled lever which can rotate about a rotation axle, which is designed to be fixed in position on the housing, and whose one end is connected in a jointed manner to one of the two slides via a rotation axle whose position can vary and which is aligned on an axis parallel to the fixed rotation axle, and the other angled arm of the angled lever can be moved, by rotating the angled lever, into a position locking the second slide. <IMAGE>
