Abstract

A contact-making apparatus for electrical connection of a unit under test to an electrical test device. The apparatus has a plurality of electrical test contacts, which are associated with at least one holding element, for making contact with the unit under test. An adapter device increases the distance between adjacent contact paths. The adapter device has contact elements for touch contact with the test contacts. The contact elements are comprised of noble metal or of a noble metal alloy, or of an alloy having at least one noble metal component, or of electrically conductive plastic. The invention also relates to a corresponding method of forming the contact elements by heating and then cooling and then forming the apparatus.
