The contact bar comprises an outer bar having a U-shaped cross-section and a plurality of bar portions located therein and separated therefrom by an insulating layer. The bar portions are insulated against each other by intermediate insulating layers in partition planes extending laterally as well as parallel to the longitudinal edge. The bar portions are produced suitably by a punching out of a bar such that they, when fitted into each other, will supplement themselves again to a bar such that a shorter bar portion cut proceeding from the upper longitudinal edge of a longer bar portion fits into the longer bar portion. The longer bar portion is at the side facing the end of the contact bar, at which only the connecting contact for a power source is located is considerably narrower than at the opposite side where the drop wires will contact the bar portion upon a yarn breakage. The bar portion which are fitted into each other have, therefore, their connecting contacts located at the ends of the contact bars and a connection leading therefrom to a separately located optical annunciator device is provided, which device displays in which at the bar portions which are insulated against…
