摘要： An electromagnetic switching device includes an electromagnetic drive device and at least one electrical contact that, when a starting current is applied to the drive device, can be transferred by the drive device from a disconnect position (contact opened) into a bridging position (contact closed). When the switching device is fully installed, the contact can be blocked in the disconnect position and can be mechanically blocked in the disconnect position by an arresting element that can be connected to the switching device. As a result, the contact remains in the disconnect position even when the starting current is applied to the drive device.

摘要： 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.
