In the case of a push-button film switch, it is intended that it be possible to close two circuits simultaneously in one switching chamber. Conductor runs 14, 14', 15, 15' of two circuits end in the switching chamber 4 for this purpose. The conductor runs 14, 14' of the first circuit largely enclose the conductor runs 15, 15' of the second circuit. The first circuit has a plurality of inwardly projecting first contact surfaces, and the second circuit has a plurality of outwardly projecting second contact surfaces. The first and second contact surfaces are located on a circular ring K within the switching chamber 4 and alternate on the circular ring circumference. <IMAGE>
