Abstract (en)
[origin: ES8200195A1] The invention relates to a circuit arrangement for actuating an electromagnetic switchgear comprising a switch position indicator, by means of a leading contact that closes a circuit to supply current to an actuating coil of an electromagnet. Main contacts of the switchgear close just after the leading contact. The electromagnet holds all of the contacts in their actuated positions until current through its coil is interrupted.
