The switching arrangement comprises three insulating layers (1, 2, 3) whose central insulating layer (2) has openings (7) which are arranged in the form of a grid. The openings (7) are surrounded on both sides of the insulating layer (2), which is constructed as a film, by annular switching-contact surfaces (5 and 9 respectively) which are electrically connected to one another in a suitable manner via conductor tracks. The insulating films (3 and 1 respectively) which are arranged above and below the insulating film (2) carry contact surfaces (11 and 12 respectively), which are likewise in each case arranged in the form of a grid, on their inner sides, the grid of the contact surfaces corresponding to the grid of the holes (7). If a pressure is exerted on the switching arrangement in the direction of the arrow in the region of a switching point, the contact between the switching-contact surfaces (5 and 9) is closed by the contact surfaces (11 and 12) making contact.
