An electromagnetic relay, particularly useful for telecommunications switching purposes is described. The relay has a series magnetic circuit comprised of a magnetic core encircled by an excitation winding, a short circuit yoke arranged in parallel to the winding axis of the core and two magnetizable flat armatures pivotally mounted at the front end of the short circuit yoke. The armatures are biased into a rest position by contact spring sets and thereby form two working air gaps with the poles of the magnetic core. In their operating positions the armatures magnetically bridge the short circuit yoke and the magnetic core. |
