Abstract
An engaging relay for starter devices of internal combustion engines as a pull-in winding of which is to be switched on via an auxiliary relay. It is provided for the purpose of a space saving, cost effective arrangement and design of the auxiliary relay that the auxiliary relay is arranged in the contact space of the engaging relay. One end of its relay winding is electrically connected in this case to the magnet core, which conducts frame potential, of the engaging relay, and the other end is electrically connected to a connecting part fastened in the switch cover of the engaging relay. A starter switch for the internal combustion engine is to be connected to this connecting part, which is constructed as a terminal, in order to switch on the engaging relay via the auxiliary relay integrated in it.
