Abstract
A polarized electromagnetic relay includes an operating winding on a core and a two-legged pivotal armature whose first leg forms a first working air gap with one pole of the winding and whose second leg forms a second working air gap with an angular yoke. A permanent magnet is arranged parallel to the operating winding and provides a magnetic flux which is closed partially by way of the first armature leg and the first working air gap and partially by way of the second armature leg and the second working air gap. The armature is pivotally supported on a yoke plate which extends parallel to the operating winding and in alignment with and separated from a leg of the angular yoke. The angular yoke and the yoke plate each include a flat surface portion for mounting opposite end portions of the permanent magnet.
