A break contact arrangement is disclosed. One piece spacers provided with angled-off arms determine the mutual spacing of contact segments and guide the contact segments within a holder comprising side walls and sheet metal covers. The contact segments are spaced by the arms of the spacers. Each spacer includes a U-shaped central portion which is received in a recess of the contact segments and extensions at opposite ends which are fastened to the side walls of the holder. The contact forces are supplied by one-piece springs which have spring arms for each contact segment. The break contact arrangement is particularly well suited for pullout-type low-voltage and medium-voltage switchgear for connecting conductors of rectangular cross section.
