Balanced Armature Type Relay ABSTRACT OF THE DISCLOSURE: __________________________ A balanced armature type relay includes a coil assembly(2)with a coil(20)and an ion core(21)extending through the coil (20), an armature assembly with a pair of frame-shaped upper and lower armatures(3, 4)disposed parallel to each other and so as to surround the coil(20), and a pair of contact units(6, 8) operated by the armature assembly. The coil(20) is covered with a molded portion(23) which has a pair of lateral studs(24)integrally formed with it, the studs(24)defining a horizontal axis about which the armature assembly is pivotal. High accuracy in the positional relation between the pole faces formed by extending ends of the iron core(21)and the respective ends of the armatures(3, 4)cooperating with the pole faces is achieved by the fact that both the pole faces provided on the iron core (21)and the studs(24)form part of the coil assembly which is formed as one common block. At the same time, a very thin relay is obtained since the overall vertical dimension of the relay may be restricted to the height of the coil.
