arranged and consists of an elastic material, e.g. B. from a polyurethane foam with open cells. An adhesive is applied to the opposite sides of the spacer 42 and protected against undesirable adhesion prior to assembly by a protective layer, not shown. The protective layer is removed from the spacer 42 in order to expose the gill material which, after the switch has been installed, connects the blade parts 22 or 24 with the spacer 42 in an interlayer construction Spacers 42 in the longitudinal direction to the corresponding opposing sets of fork prongs 34 and 36 of the ladder arrangements 30 and 32, respectively, these openings opening towards these fork prongs. It is also possible to use a similar offshore holder 46 according to FIG. 6 together with a large number of separate openings 48 which open to the opposing sets of fork prongs 34 or 36 of the ladder arrangements.

The support elements 18 and 20 with the outlines of the Conductor anoidations 30 and 32, which are produced by the stamp or by the embossing process on the same are imprinted, are set to a temperature between 149 ° C and 177 "C before the switch is installed heated. Through this heating, the LeiuTanierungen firmly connected to the support elements within the outline of the conductor arrangement. While the Support elements and conductor arrangements are kept at this temperature, becomes a corresponding one Tool or a corresponding stamp for embossing the sheet parts 22 or 24 and the corresponding Fork tines 34 and 36 of the ladder assemblies used to form the frustoconical projections SO ^ s and 52, respectively, which are best illustrated in FIGS. 3 and 5 can be seen. The stamp ve, stays with the Support elements during the cooling of the support elements to ambient temperature engaged to the To prevent protrusions from springing back into the flat configuration. Once the switch is installed is, take the openings 44 of the spacer 42 Projections 50 and 52, as best shown in FIG. 3 can be seen, the spacer 42 being the apex which normally keeps projections apart. As soon as the sheet parts 22 and 24 of the Support elements a pressure above a certain vorbe value perpendicular to their flat surfaces exposed, such as B. when a vehicle occupant is sitting on the seat 12, the .so Spacers 42 compressed so that the apices of projections 50 and 52, respectively, engage come together and the switch is closed. During this procedure, the recessed ones provide support Parts of the support elements, the recessed parts of the I, citer arrangements, so that no plastic deformation the ladder arrangements takes place.

The interconnected conductor assemblies form a conductive path through them corresponding handle parts 38 and 40, respectively, between a pair of connecting terminals 54 and 56, see FIGS. 2 and 5. These terminals allow a pair of leads 58 and 60, respectively, to be connected as well of the switch within the electrical line. 4 shows an enlarged section of the terminal 54 with a connecting member 62 which supports the lead 58 through a section 64 and they electrically connects by a part 66. The link has a flattened portion 68 with a opening 70, which with the openings 72 and 74 in the Handle parts 26 and 38 of the support element 18 and the conductor arrangement 30 are aligned. A metal insert 76 extends through the aligned openings and has an upper support lip 78, which with the Upper side of a handle part 26 connected in a suitable manner and covered with a polyester cover 80 is, see also F i g. 2, in order to avoid electrical contact of the insert 176 with a conductive seat part. The lower side of the insert 76 has a lip 82 which fits the portion 68 of the link 62 in the Holds engagement with the handle portion 38 of the conductor assembly 30. Terminal 56 is similar to terminal 54, so that it is not described in detail; it should only be noted that the handle parts 38 and 40 of the Conductor arrangements 30 and 32 are laterally offset from one another, so that the terminals with one another even if there is no spacer or the like between the handles Support elements is provided.

Within the corresponding levels of the link arrangements reduce the distances between the Fork joint η 34 or 36 the rigidity that is given to the switch by the Kontakteiemcntc, as well as the possibility of causing discomfort on the seat 12 for the vehicle occupant. Between Projections 50 and 52 have the fork prongs 34 and 36 corresponding strip parts 84 and 86, the Width is smaller than the diameter of the indentations, the purpose of this measure being to reduce the stiffness imparted to the switch by the ladder assemblies and the possibility of discomfort for to further reduce a vehicle occupant.

As can be seen from FIG. 2, the bottom is of the blade part 20 is coated with an adhesive which is protected by a cover part 88. As soon as this Cover part is removed, the adhesive attached the switch 16 on a paddle of the seat cushion 14 before the switch is covered with the material that forms the seat surface. After the switch is overdrawn the cover material and the upholstery work together to create the switch in the area of the seat surface to keep.

It is noted that an alternative according to the invention is to have protrusions only on one of the both contact elements. This embodiment is also intended to be encompassed by the concept of the invention will
