Abstract
A polarized electromagnetic relay including a coil body positioned over a core, and having at least one winding thereon. A permanent magnet is positioned in close proximity to the coil body. An armature externally embraces the coil winding and with the permanent magnet forms two working air gaps. Contact elements are provided embedded in a pedestal, the contact elements being disposed below the coil body. A monostable or a bistable switching behavior of the relay can be achieved by varying the design and disposition of the coil body, the windings, and one or more permanent magnets.
