The relay is composed of a yoke section having air gaps at four diagonal positions and an H-shaped armature block (7) having four armature portions which are positioned in the air gaps of the yoke section, respectively. The armature portions are arranged to enable a parallel movement. The yoke section is composed of two yoke units, each composed of a first pole piece (1) approximately U-shaped and a permanent magnet (6) having the one pole positioned over the centre of the lower surface of the first pole piece. A second pole piece (5) contacts the other pole of the permanent magnet (6) and forms air gaps between both ends and both free ends of the first pole piece (1), respectively.
Electromagnet with yokes and an armature having a permanent magnet with pole pieces at its pole faces protecting beyond the magnet axis, this axis being perpendicular to the direcion of movement
