Definitions

• Switch in particular steering column switch for motor vehicles
• the invention relates to a switch, in particular a steering column switch for motor vehicles, comprising a housing, with a movable in the housing, modulatable via an actuator switching piece, wherein the switching piece has a control part surrounding the guide, wherein the control part cooperates with a housing-side control cam.
• Such switches find their use in many areas of technology.
• the various functions of the lighting system, the direction indicator system and / or the windscreen wiper system can be realized.
• the functional positions can be designed to be tentative and / or latching. Depending on Functional position are actuated in operative connection with the switching piece standing functional elements.
• the present invention has the object to provide a simple to manufacture and haptic pleasant and functionally reliable switch.
• an elastic ring element is arranged in a groove between the guide and the control part.
• the guide and the control part can be subject to tolerances. Due to the elasticity of the ring element, a game between control part and leadership can be compensated. This allows a backlash-free storage of the control part within the guide. This type of storage provides a pleasant feel when switching the actuator.
• the ring element via the elasticity of the ring element switching noise be reduced because the ring member acoustically decoupled from each other the control part and the contact piece. Due to the fact that the ring element lies in the groove, it is arranged in a captive manner, in particular under slight preload, on the control part. By virtue of the linear arrangement of the ring element on the guide, frictional forces between the control part and the guide when the control part is moved are also kept very low.
• the control part may have a round and in particular a circular cross-section at least in the section on which the groove is provided.
• control part has a first shoulder-shaped material portion and if provided adjacent thereto second shoulder-shaped material portion, wherein the groove is provided between these material portions.
• the side facing away from the groove of the second material section can then serve as a stop for a pressure acting on the control part against the control cam spring.
• the first material section can merge into a locking body cooperating with the control cam.
• the ring element is circular in cross section.
• a particularly advantageous embodiment of the invention provides that the guide is polygonal in cross section. This has the advantage that the guide does not rest along the entire circumference of the ring element, but only in sections. In this way, the friction between the ring member and the guide is reduced. In addition, each adjacent spaces between two contact points open spaces in the material of the elastic ring member can escape. In this way, a particularly tolerance-insensitive arrangement is created.
• the guide may be in cross section, for example, quadrangular, in particular square.
• a bearing can be created which has the same frictional resistance with respect to two mutually perpendicular axes.
• This is particularly advantageous for steering column lever, which have two mutually perpendicular operating levels. This is the case, for example, in the case of a steering column switch, in which the high beam of a motor vehicle can be actuated in a first operating plane and the direction indicator in a vertical operating plane.
• the guide can also be triangular in cross-section, whereby the number of contact surfaces between the ring member and the guide is reduced to three, whereby the friction can be further minimized.
• a particularly preferred embodiment of the invention provides that the actuating member is mounted on a bearing with the aid of a universal joint. With such a joint, the actuator can be precisely stored in a simple manner so that it is pivotable about two mutually perpendicular axes of rotation. In conjunction with the storage of the control part in the guide by means of an elastic ring element results in a very simple and play-free storage.
• a particularly advantageous kinematics of this arrangement results when the actuator between the bearing point and the contact piece has a aligned with the longitudinal extent of the control part material portion. As a result, occurring lateral forces are minimized when operating the switch.
• Figure 1 is a perspective view of a switch according to the invention
• Figure 2 is a schematic, sectional side view of the switch of Figure 1;
• FIG. 3 shows a perspective view of the switch according to FIG. 1 in accordance with the viewing direction indicated in FIG. 2 with III;
• FIG. 4 shows a schematic representation corresponding to FIG.
• a switch is generally designated by the reference numeral 2. This has an elongated actuator 4, which can be handled at an unillustrated in Figure 1 free end by an operator.
• the actuator 4 has a contact piece 6 at its front end.
• the switching piece and the actuator are firmly connected to each other and can also be integrally formed with each other.
• the actuator 4 is mounted on a bearing designated 8 in total bearing by means of a universal joint 10.
• the universal joint 10 has a housing 12 which surrounds the actuator 4. At this two bearing pins 14 are arranged, which define a first pivot axis 15 of the actuator 4.
• the bearing pins 14 are received in a housing section of the switch 2, not shown.
• the actuator is further pivotable about a pivot axis 17 which is perpendicular to the pivot axis 15.
• the pivot axis 17 is defined by formed in the housing 12 pin receivers 16, in which formed on the actuator 4 pins 18 are added.
• the contact piece 6 protrudes with its end facing away from the actuator 4 in a only partially shown housing 20, in which a control cam 22 shown in Figure 2 is arranged.
• an elongate control member 24 is disposed within the contact piece 6. This engages at its end facing away from the control cam 22 an opening 26 formed in the contact piece.
• the control part 24 has a stop 28 which rests against the contact piece 6 and thus defines an end position of the control part 24.
• the material portion of the contact piece 6 forming the opening 26 has a plurality of slots 29 along the circumference of the opening.
• the stop 28 has bevels 31 at its free end.
• the control part 24 Adjacent to the latching body 30, the control part 24 has a first, shoulder-shaped material section 32. Adjacent thereto, a second material portion 34 is provided, which is also formed shoulder-shaped and also serves as a stop for the compression spring 33. Between the material portions 32 and 34, an elastic ring member 36 is arranged, which abuts radially outside at least in sections on a guide 38 formed within the switching piece 6.
• the guide 38 is also shown in Figures 3 and 4. From these views it can be seen that the guide 38 is square in cross-section. This has the consequence that the ring member 36 is not applied along its entire outer circumference of the guide 38, but only in four contact areas 40. Between these free spaces 42 are formed, can dodge into the material of the elastic ring member 36. In this way, the control part 24 is mounted without clearance in the guide 38 of the contact piece 6.
• the guide 38 is not square in cross section along its entire length. With reference to FIG. 2, the guide 38 has a wall section 44 opening at the opening 26 on, which is circular in cross section. Between the wall portion 44 and the cross-section polygonal guide 38, an edge 46 is formed.
