Polarized electromagnetic miniature relay

Polarized electromagnetic miniature relay with a tongue armature which is arranged within the coil body approximately along the coil axis and is mounted at one end, and the free end of which is arranged between two yoke plates located opposite one another which also each form a pole shoe which is coupled to a permanent magnet arrangement arranged on one end of the coil body, said permanent magnet arrangement being designed with four poles with two polarization directions which are opposite to one another and parallel to said coil axis, the coupling surfaces between said two pole shoes and in each case of two unlike pole faces of said permanent magnet arrangement being at right angles to said coil axis, in which a ferromagnetic housing cap serves as a guidance plate, and in which flux transition components which lie laterally against said housing cap are formed on said yoke plates.
