ABSTRACT:
An interlock mechanically locks out of one of two electromagnetic switching devices which are located side by side while the other switching device is in its closed position. The interlock achieves this lockout by adapting the moving parts of the switching devices, which are to be coupled, to locking elements. The locking elements are preferably slide bars which extend from the interlock. The moving parts of the switching devices form coupling members for auxiliary switches. These auxiliary switches can be set onto the switching device. The slide bars conform to the coupling members. This makes it possible to mount an interlock, for two electromagnetic switching devices located side by side, in place of or in addition to auxiliary switch units.
