ABSTRACT:
An electromagnetic relay is provided with an electromagnet system with a U-shaped core yoke and an essentially flat armature, which form a working air gap on a longitudinal side underneath the coil winding. One yoke limb lies immediately on the coil winding, so that the make motion of the armature is towards the coil. In this way, a relatively large contact room is formed underneath the yoke limb and a movable contact spring extends approximately parallel under the armature. The contact spring is actuated by the armature which draws an actuating element. The relay enables a relay for high switching capacity with a changeover contact and with large insulating distances between the magnet system and the contact arrangement.
