An electric contact arrangement has a plurality of movable contact elements which are biased oppositely with respect to a like plurality of associated stationary contact elements by spring elements comprised of elastic plastic. The plastic spring elements may be formed on a contact carrier for use of the contacts as bridge contacts having a high degree of voltage stability.

Electric contact arrangement

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.
