Abstract

Apparatus for electrical function testing of wiring matrices, particularly of printed circuit boards. In the electrical function testing of wiring matrices, particularly of printed circuit boards, the number of required leads and switch elements can be drastically reduced. In the present apparatus, every measuring locations of the printed circuit board can be selected by an associated busbar and by an intermediate mask that prevents the contacting of non-selected measuring locations. The busbars preferably are orientated transversely relative to the principal direction of the wiring of the printed circuit board.
