Abstract: A light guide is provided that includes a fiber bundle, a jacket, a proximal end, a distal end, and a terminated end face. The fiber bundle has a plurality of optical fibers. The jacket encloses at least a part of the plurality of optical fibers and/or the fiber bundle. The jacket has a maximum outer lateral dimension that is greater than a maximum outer lateral dimension of the fiber bundle by at most 500 ?m. The terminated end face is on the proximal end and/or the distal end. The terminated end face has a maximum lateral outer dimension that is not larger than the maximum outer lateral dimension of the jacket.

Abstract: A method and apparatus for adjusting contact springs of a relay with a laser beam. To adjust contact springs a laser beam is trained on specific points of a matrix field on the contact spring that is to be adjusted. For each of the points, the adjustment path that can be produced is stored in a memory. Through determination of the position of the armature or the contact spring by means of an electro-optical device and by comparison of the measurement results with the stored correction values, those points are selected that are to be irradiated with the laser beam.

Abstract: An electromagnetic relay has a bar-shaped armature which is mounted at one end at a coil flange in a carrier comprised of insulating material, in which center contact blades are also mounted at opposite sides of the armature such that movement of the armature is transmitted to the contact blades through the carrier, thus eliminating the plunger which is normally present for contact actuation. The offset positioning of the contact blades with respect to the armature in the carrier causes friction which substantially prevents damaging impact of the contact pads of the contact blades with respectively mating stationary contact pads.
