Abstract

The contact piece (1) has at least two contact fingers (2), which form at least partially strip conductors (4) which run parallel to each other. A transverse support allows the strip conductors to be moved. Iron bars (12) for example are arranged between the contact fingers for increasing the pressure force and which have an increased permeability in comparison to the air gap (13) formed between the contact fingers. An independent claim is also provided for a contact arrangement with a contact piece and a counter contact.
