Abstract
A contact device for an electric contact for electrically testing an electric test object, comprising a contact head and at least one printed circuit board. The contact head has a plurality of guide bores in which elongated contact elements that buckle elastically in a lateral direction upon contacting the test object are mounted in a longitudinally movable manner. One end of the contact element is used to contact the test object and the other end is in contact with first contact surfaces which are arranged in a specified pattern and which are located on a face of the printed circuit board in a first, central region of the printed circuit board face. Second contact surfaces are arranged in a further specified pattern, are electrically connected to the first contact surfaces through the printed circuit board, and lie on the other face of the printed circuit board in a second, central region of the printed circuit board face. Third contact surfaces lie on the other face of the printed circuit board in at least one first peripheral portion of the printed circuit board face. At least some of the second contact surfaces are electrically connected to at least some of the third contact su…
