Abstract
A contact configuration, whose axially opposed contacts have a current-supplying stud, a cup-shaped contact carrier and a contact plate set up on the rim of the contact carrier, a support consisting of material with poor electrical conductivity being provided to mechanically stabilize the contact plate. The support forms a tubular supporting region and is located on a graduated circle whose diameter is at most equal to the diameter of the current-supplying stud. The diameter of the current-supplying stud thereby equals at least 50% of the external diameter of the contact carrier. The length of the support has a considerably smaller cross section in its middle than in its base and top region so that the ohmic resistance of the support is at least approximately one magnitude greater than the ohmic resistance of the contact carrier and contact plate.
