Abstract (en)
[origin: EP0329138A1] The relay has a coil with a core and one or two angle-shaped armatures (4, 15). The two armatures each have a second limb (4b; 15b), running approximately parallel to the coil axis, and an extension on which a restoring spring (7) engages. Each armature operates a contact spring connected to it. <??>As a result of the displacement of the bearing point onto the end of the second armature limb, increased friction is produced at the contact points and hence a reduction in the tendency to welding. As a result of this type of bearing, there is also a reduction in the effective spring force of the restoring spring while the armature is being attracted, thus increasing the reliability of armature attraction, with a constant excitation. <IMAGE>
