Claims (7)

. The invention relates to a steering column switch for claims: Motor vehicles with a 1. Steering column switch for motor vehicles with th, additional switching device, in which the one housed in the shift handle, additional shift handle rotatably mounted on the shift stick, in more switching device, in which the shift handle on the S rere radial switch positions is adjustable and a shift stick rotatably mounted in several radial centrally mounted switching bridge actuated, the switch-off positions can be adjusted and a switching bridge, which is centrally suspended from the switch handle rotation position and actuates contacts, which connects depending on each other, which are fixed in a head carrier connected to the switch stick of the switch handle rotation position, and which connects, which has a curved shaving circular path in a contact carrier connected to the switching stick 10 to which the contact carrier is also connected, and switching curve,
in which the contact carrier also has a switching device arranged in the switching handle, which is arranged in the switching handle, characterized in that it has already been proposed (Patent 2,049,849.1). the switching bridge (19) on a by means of the switching 15 This additional switching device is designed in such a way, handle (17) actuatable driver (15) radially fixed that a switching bridge is loosely attached to a guide extension and axially movable and the contact carrier is pushed on and is set with their two arms in the halves of the switching handle under the pressure of one of the arms on the driver. This supporting spring (18) means that the driver switching bridge slides on the switching curve of the contact under spring pressure (16) on the locking circular path ao carrier around 'connects which in the contact carrier a ^ esetz- (Fig. 4) slides and that the axial mobility th contacts depending on the switching position of the switching bridge on the driver so limited Schaltgritis each other. The switching bridge is that the switching bridge in the axia switching curve assigned to the highest with its contact-making parts both on the point (114) of the switching curve and on the contacts of the contacts limit position of the driver of contacts 25, the switching curve is safely separated on a circle (12, 13). is around the steering column axis, the diameter of which 2. Steering column switch according to claim 1, that is greater than that of the circle on which it is characterized in that the switch handle (17) are on contacts This simultaneous resting of the two opposite inner sides each two switching bridges on the switching curve and on the Has ribs (172), between which there is a corresponding contact of the contact carrier, however The associated guide arm (153) of the driver is difficult to achieve. Due to the manufacturing (15) is led. tolerances of the switching curve part and the contacts 3. Steering column switch according to claim 1 or 2, the contact carrier shows that the switching bridge characterized in that the driver (15) either only on the switching cam part or only on consists of a sleeve (151) and one at the end 35 of the relevant contact. Tin first case is This sleeve arranged, disc-shaped, the electrical connection of the contacts no longer Part (152) composed in one piece and that ensures, while in the second case a game in Switching bridge (19) is guided on this sleeve. the detent occurs. This Rastungsherspiel is called 4. Steering column switch felt very annoying after one of the disturbances. Proverbs 1 to 3, characterized in that the 40 The object of the invention is to provide a Switching bridge (19) bent at right angles Lap steering column switch for motor vehicles with an im pen (191), in which slots (192) a switching handle accommodated, additional switching let are, and that the driver (15) to create the nose direction of the type mentioned at (157) that engages in these slots (192) to ensure proper electrical contact of the are. 45 Suhalt bridge with the contacts of the contact carrier 5. Steering column switch is secured after one is switched on and the locking spid is avoided. Proverbs 1 to 4, characterized in that this is achieved according to the invention in that between the switching bridge and the driver a switching bridge on one by means of the switching handle Helical compression spring (18) is arranged. actuatable driver radially fixed and axially limited 6. Steering column switch after one of the An 50 is movably attached and under the pressure Claims 1 to 5, characterized in that there is a spring supported on the driver, between the driver and a wall (171) that the driver is under spring pressure on the wheel Shift handle a further screw pressure stungskreisbahn slides and that the axial movement spring (16) is arranged. possibility of the switching bridge on the driver in such a way 7. Steering column switch according to one of the adjoining 55 is that the switching bridge in the highest claims 1 to 6, characterized in that the point of the switching curve associated, axial limit of the contact carrier (11) consists of two adjacent positions of the driver of the contacts safely delimiting sleeves (111, 113) different separates. In addition to the advantage of the missing Ra diameter and a gap between these sleeves, there is also the advantage of the particularly connecting disc (112) integrally making good contact, since the contact spine assumes that the sleeve (111) with the smaller one printing a certain _{Schleifbewegun>:,} clock listed on the Kon-diameter on the shift stick (10) carries out, so that the contacts are inserted itself and is mounted so that clean on the disk. (112) the contacts (12,13) are arranged and further advantageous measures relate to the fact that the face of the sleeve (113) with the 65 on the special design of the driver, the larger diameter according to the switching bridge and the account holder.
k.L'rve has a locking circular path. The invention is explained in more detail using an exemplary embodiment
