Abstract
The contactors for a pair of switchgears are coupled via a blocking body in such a way that upon activation of one switchgear the other switchgear, which acts upon the blocking body in a sense opposite to that of the first switchgear is blcoked in its activation motion. To this end, each slide that is guided in a guide housing is rigidly connected with a tappet in the direction of motion via the collar of a collar screw which screwed into the slide. Each of the lobes of the heart-shaped blocking body are essentially rigidly connected with one of the tappets via dogs in the direction of motion.
