Abstract of the Disclosure Disclosed is a transfer-type electromagnetic relay in which movable contact studs are attached to both ends of a leaf spring fixed onto an armature for reducing the relay thickness. Leads for fixed contact studs are made of a soft magnetic material. Permanent magnets are placed trans- versely on the leads with poles of like polarity brought nearer to the leads. When selectively magnetized by a coil wound around a housing, the armature is swung to carry out contact transfer with a high sensitivity. The relay is rendered self holding by the permanent magnet and the soft mag- netic leads. Only one permanent magnet may be used for a current-holding relay. The leaf spring has transverse and longitudinal arms for insuring contact between the movable and fixed contact studs and connection of the movable contact studs to leads thereof.
