The invention relates to a momentary-contact switch device having a plurality of momentary-contact switches which are grouped to form a key panel and act by means of their operating elements on at least one contact film which has elastic properties. The object of the invention is to increase the number of ways of switching which can be electrically isolated from one another. The object is achieved by means of at least three contact films (1, 2), which are arranged one above the other, are provided with conductor tracks (5, 6) and contact points (7, 8), are separated from one another by means of intermediate layers (9, 10) consisting of insulating material, and have in each case one recess (11, 12) in the region of the contact points. <IMAGE>
