Contact surfaces for keys or keyboards in which conductor paths are fed to contact surfaces (6, 7). The object of the present invention is to design the contact surfaces (6, 7), which are applied by the screen printing process, such that there is no need for a double screen printing process. The contact surfaces (6, 7) now consist of graphite surfaces applied onto a base (1), which graphite surfaces are made contact with on the sides by means of in each case a large-area conductor path, designed as an electrode (2, 3). <IMAGE> |
