  • Patent number: 4956623
    Abstract: A relay having a coil including a core also has either one or two angled armatures. Each of two armatures has a second leg extending approximately parallel to the axis of the coil as well as an extension upon which a restoring spring acts. Each armature has a contact spring which is connected thereto. Due to the displacement of the bearing location the end of the second armature leg, increased friction at the contact locations arises as well as reduction in the welding tendency of the contacts. Reduction of the effective spring force of the restoring spring during armature attraction also arises due to the seating of the armature so that reliable operation is provided without increased electromagnetic excitation.
