ABSTRACT:
An additional switchblock is laterally connected to a contactor of a magnetic control relay. The terminals of the switchblock and contactor are provided for on the front side opposite that of the support bar. A hook connection is used between the two lateral surfaces. When the hooks formed on the additional switchblock are inserted into corresponding recesses in the contactor, a formed-on ring portion of the additional switchblock actuating element engages with a switch position indicator extending from the front side of the contactor so that the actuating coupling is assured. The detent preventing the additional switchblock from sliding back away from the contactor is accomplished via detent arms formed on the additional switchblock arms and having wedge shaped projections which engage recesses in the contactor cover.
