ABSTRACT:
In a transfer-type electromagnetic relay, movable contact studs are attached to both ends of a leaf spring (38) fixed onto an armature (39) for reducing the relay thickness. Leads (26, 27) for fixed contact studs are made of a soft magnetic material. Permanent magnets (46, 47) are placed transversely on the leads with poles of the same name brought nearer to the leads. When selectively magnetized by a coil (48) wound around a housing (21, 22), 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 magnetic 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.
