Abstract (en)
[origin: US4578547A] Electric switches whose fixed contacts (3) are formed by the conductors on a printed circuit board (1), which are coated with a layer of noble metal, the connections between the fixed contacts provided on a contact path (2) and electrically connected among each other, extend outside the contact paths (2) of the movable contacts. Prior to the application of the layer of noble metal the connecting lines are covered and, therefore, a considerable saving of noble metal results.
