Steering column switches for automobiles

The invention relates to a steering column switch for motor vehicles with one or more switching devices which can be controlled by means of a switching lever and which are fixed to the switch housing Parts are set.

There is a growing desire to have the switching devices for a wide variety of motor vehicle circuits on the steering column accommodate. To do this, so-called steering column switches with several shift levers are required these switching devices can be controlled independently of one another. For example, there is already a switching device to control the direction indicator, a switching device to control the Schaibemcischanlage, one as Low beam / high beam switch trained switching device and a switching device designed as a washer switch for the windshield washer system in a switch housing been housed.

In such a steering column switch with a large number

of Scnalteinric-iitimgen äereitot the accommodation of the Switching devices and the wiring of the switching devices with each other considerable difficulties.

It is the object of the invention to design a steering column switch of the type mentioned in such a way that the various Switching devices can be easily and clearly defined and wired together.

This is achieved according to the invention in that the switching devices on one or both surfaces of a Console plate with a central, the steering column enclosing sleeve are set diametrically to the steering column and that the switching connections between the switching devices are designed as contact strips, which are connected to the Outside of the sleeve or the boundary wall of the * console plate are kept at a distance. All switching devices can then be fixed to the contact plate and connected to one another, including the rigid, bare contact strips are electrically separated from each other and are clearly defined on the console plate.

The molding of these webs on one as a plastic injection molded part trained console plate is made possible without a Sehieber tool that the webs in the longitudinal axis the sleeve and are offset from one another over the circumference of the sleeve.

The connection and the connection of the contact strips in the Switching devices is facilitated by the fact that the contact strips connected to angled ends of the connection contacts of the switching devices, preferably welded are.

A simplification of this type of wiring can be achieved according to a further embodiment in that Gin Ansohlußkontakt a switching device itself as

Contact strips _{formed IsZ 1} whose free end is connected to an angled end of a connection contact of another switching device.

The definition of the switching devices and their wiring is further completed by the fact that the fixed on the two surfaces of the console plate Switching devices are additionally defined by a base plate or cover plate and that in the base plate or cover plate connection contacts are set, which via contact strips with each other or with the switching devices are connected. The entire steering column switch can then be easily accessed via connection contacts on the base plate connected.

The invention is based on an embodiment of a steering column switch shown in the drawing four shift levers and four switching devices explained in more detail. The drawing shows a top view of the console plate 10 with cover plate removed «

The console plate 10 has a central sleeve 11 which surrounds the steering column 12. To the left and right of this sleeve 12, the console plate offers space for defining separate switching devices 34 and 35. These switching devices 3 ^ and 35 have rotatably mounted switching levers lh and 17, which are themselves designed as drivers with switching bridges, as the pivot pins 15 and 18 show. As the switching levers 16 and 19 indicate, two switching devices are also set on the underside of the KonsoJ.platte 10. The design of these switching devices does not need to be discussed in more detail in the context of this invention, since this is not important for the present container design with improved fixing of the switching devices and their easier wiring.

It should only be noted that the over the gear lever 16 and 19 controlled switching devices are additionally held by a base plate, which also has connection contacts can carry and the screw connections together with the cover plate on the opposite side of the console plate 10 is connected to this.

As can be seen from the drawing, contact strips take over the connection between the switching devices, e.g. the angled end 27 of the connection contact 37 of the switching device 3 ^ connected to the contact strip 29. This contact strip 29 is connected by webs 21 the end wall 22 of the console plate 10 out and at a distance held to other contact strips. The other end of the contact strip 29 has the angled end 28 a connection contact of the switching device 35 is connected.

The connection contacts 31 and 32 cooperating with the Sehaltbrüeke 36 are fixed on the console plate 10. Their ends are themselves designed as contact strips 23 and 25, which are connected to the angled ends 2h and 26 of connection contacts in the area of the switching device 35. These contact strips 23 and 25 are fixed and guided by the webs 20 on the outside of the sleeve 12 of the console plate 10.

It is easy to see that such fixed contact strips can not only connect connection contacts of the two switching devices 34 and 35 with one another. Much more Any connection contacts of all switching devices can be connected to each other and to connection contacts, which are fixed either in the base plate or in the cover plate.

The entire steering column switch is covered by a cap 30, which has openings for all shift levers lh, 16, 17 and 19 *

The sleeve 12 has an opening I3 through which the * Switching cam of a switching device designed as a direction switch protrudes. This is in the exemplary embodiment shown the switching device which is not shown in detail and which can be controlled via the switching lever 19.

The webs 20 and 21 are in one piece on the console plate molded. They are made up of tool technology and manufacturing technology Reasons offset from one another in the longitudinal axis, their offset corresponding to the width of a contact strip. In addition, these webs 20 and 21 are over the circumference of the sleeve 12 or offset across the width of the end wall 22, since then there is no backside in the longitudinal direction of the Ridges occurs.

In the same way, the contact strips 23, 25 and be set when the webs 20 and 21 recesses of have the width of these contact strips. However, this design then requires a tool with a slide.
