ABSTRACT:
A locking device for two juxtaposed and spaced electromagnetic switching devices is disclosed. In the switching devices, contact carriers are provided which can be moved back and forth between first and second switching positions. The motion of the contact carriers is regulated by a latching member which can be tilted into a latching position by actuating one of the contact carriers relative to the other contact carrier. The latching member is held in a frame and is preferably in the form of a balance beam. The latching member is pivotable on a support member in the form of a pin. The frame itself is engageable with a shoulder-shaped extension in openings of the housing walls of the electromagnetic switching devices. The locking device can be adapted to different conditions in a simple manner by adjusting the pin which is held in a threaded hole of the frame.
