Abstract (en)
[origin: US4509025A] An electromagnetic relay has a hallow coil body and coil having a longitudinal axis with a bar-shaped armature pivotably mounted for movement in and extending through the coil body, a permanent magnet arrangement having polarization directions perpendicular to the coil axis, two yokes disposed in a single plain parallel to the permanent magnet arrangement, two pole plates connected to the yokes and also extending perpendicular to the coil axis, and a flux plate overlapping and spaced from the yokes and having a flat segment with the magnet arrangement being disposed in the volume defined between the overlapping area of the flux plate and the yokes, the magnet arrangement extending substantially longitudinally parallel to the coil axis. The structural arrangement of the flux plate and yokes so as to define a volume which can accommodate the magnet system permits the magnet system to be encompassed within the relay without adding to the overall length thereof, thereby adapting the relay to miniaturization. Additionally, the surfaces of the yokes and permanent magnet can exhibit a relatively large area, again without causing any increase in the length of the relay.
