ABSTRACT:
An electromagnetic relay includes a power supply element of the load circuit which is conducted around a part of the excitation flux circuit by at least one turn so that an auxiliary excitation flux is generated therein isodirectionally with the excitation flux of the winding. A reliable response of the relay is guaranteed even in relays wherein high currents are drawn by the load circuit from the same voltage source that delivers the excitation voltage, such as in relays in motor vehicles.
