Abstract:
A polarized electromagnetic relay including an electromagnet assembly, a contact section insulated from the electromagnet assembly, and a force transfer member disposed between the electromagnetic assembly and the contact section. The electromagnet assembly includes an electromagnet, an armature driven by the electromagnet, and a permanent magnet carried on the armature. The armature includes first and second electrically conductive plate elements holding the permanent magnet therebetween in a direction of magnetization of the permanent magnet and disposed to orient the direction of magnetization in parallel with the center axis of the coil. The armature is arranged linearly movably in a direction parallel with the center axis in a state where a part of the first electrically conductive plate element is inserted into a space between the outer peripheral region of the iron core head portion and the distal end region of the yoke major portion.
