Definitions

  • the invention relates to a switch according to the features of the preamble of claim 1.
  • An electrical switch with two stacked switch units is e.g. known from DE-B-25 34 838.
  • this electrical switch individually punched and bent metal sheets are evidently fixed on the base plates of the two switch units, which are formed at one end as plug contacts which extend at right angles from the base plate. If such individually punched sheets are used, the positions which the plug contacts assume relative to one another can largely be freely selected without great difficulty. So it is, as DE-B-25 34 838 shows, e.g. readily possible to bend two plug contacts belonging to the same switch unit at different distances from a longitudinal center plane from the base plate.
  • DE-B-25 34 838 shows two plug contacts of the lower switch unit and a plug contact of the upper switch unit, the end of which is located far above the ends of the two lower switch units.
  • the distance of the plug contact belonging to the upper switch unit from said longitudinal median plane is greater than that of the two plug contacts of the lower switch unit.
  • the angular position of the plug contacts is not recognizable. In any case, it is difficult to connect the two switch units to the vehicle electrical system of a motor vehicle via a single connector. Accordingly, DE-B-25 34 838 also indicates separate connection plugs for the lower and the upper switch unit.
  • the object of the invention is to provide an electrical switch of the type mentioned, which is as simple and compact as possible and which can be safely connected to the electrical system of a motor vehicle without difficulty and with a simple connector.
  • an electrical switch which, in addition to the features from the preamble, also has the features from the characterizing part of claim 1. Then a large number of plug contact ends are concentrated in the same switch area, which ensures a compact design of the switch connection area and the use of a compactly designed connector is possible.
  • the plug contact ends of the two switch units are advantageously arranged opposite one another, thereby promoting the compact design.
  • the plug contact ends of the first switch unit can be protected against undesired contact.
  • such a coupling frame can ensure that the two switch units are assigned in the correct position and that a connector is correctly installed.
  • the measure proposed in claim 11 prevents undesired bending of the plug contact ends of the first switch unit.
  • the development according to claim 11 also enables a secure position assignment of both switch units without additional aids. It is possible without difficulty to separate the switch units from one another, for example in order to be able to carry out repairs, by pulling the boards apart.
  • the steering column switch shown completely in FIG. 1 has an approximately cylindrical tubular housing 10 with two switch units 11 and 12 arranged in superimposed levels.
  • the upper, first switch unit 12 and the lower, second switch unit 11 each have a circuit board 13 or 14, each one Has base plate 15 or 16 made of plastic.
  • a multiplicity of conductor tracks 17 and 18 punched out of a sheet metal plate is cast into the base plates 15 and 16.
  • Recesses 19 or openings 20 are provided in the base plates, through which a tool protrudes during the casting process, by means of which a precisely arranged arrangement of the conductor tracks in the respective base plate is achieved.
  • the cutouts 19 and the openings 20 are indicated in FIG. 3.
  • the conductor tracks 17 have areas 21 which are to be understood as fixed contacts of the switch unit 11.
  • the conductor tracks 18 have areas 22 which are to be understood as fixed contacts of the switch unit 12.
  • the base plates 15 and 16 each carry a pin 23 or 24 on which a shift lever 25 or 26 is rotatable and about it Longitudinal axis is mounted tiltable.
  • the shift levers 25 and 26 are made of plastic, but are reinforced by a metal insert 27 and 28 to increase stability.
  • the shift lever 25 is the wiper-washer shift lever, while the shift lever 26 is the turn signal and driving light switch lever.
  • the fixed contacts 22 of the switch unit 12 are arranged at different locations along the extent of the base plate 16 of the circuit board 14.
  • both the sections of the conductor tracks 17 to be regarded as plug contacts 33 of the circuit board 13 and the sections of the conductor tracks 18 to be understood as plug contacts 34 of the circuit board 14 are arranged in the same switch region 35.
  • the plug contacts 33 and 34 have ends 36 and 37, which are bent away from the respective base plate 15 and 16 at right angles and point downward. At these ends 36 and 37, the switch units 11 and 12 can be connected to the electrical system of the motor vehicle by guiding a connector, not shown, in the plugging direction 38.
  • the switch thus has a compactly designed switch connection area 35, in which the use of a single, compactly designed connector plug is possible.
  • the ends 36 of the plug contacts 34 of the first switch unit 12 extend further outside than the ends 37 of the plug contacts 33 of the second switch unit 11, the ends 36 and 37 of the plug contacts 33 and 34 of both switch units 11 and 12 do not have any closely adjacent surfaces, so that a big one electrical safety is guaranteed.
  • FIG. 2 further shows, the ends 36 and 37 of the plug contacts 33 and 34 of the switch units 11 and 12 are arranged opposite one another. As a result, a large expansion of the switch region 35 in the circumferential direction of the housing 10 is avoided.
  • the ends 36 and 37 of the plug contacts 34 and 33 of the two switch units 12 and 11 are each arranged on a straight line 42 and 41, respectively.
  • the ends 36 of the switch unit 12 have a distance A 'from the longitudinal center plane E of the housing 10 which is greater than the distance a' of the ends 37 of the switch unit 11 to the longitudinal center plane E, as shown in FIG. 2.
  • the ends 36 and 37 of the plug contacts 34 and 33 of both switch units 12 and 11 all have the same distance b from one another on the longitudinal side surfaces 39 and 40, which corresponds to approximately half the extent of the ends 36 and 37 transversely to the longitudinal direction.
  • the ends 36 and 37 are thus arranged next to each other without risk of contact and yet compact.
  • the ends 36 of the plug contacts 34 of the first switch unit 12 are substantially longer than the ends 37 of the other switch unit 11. Nevertheless, they cannot be bent unintentionally during the assembly of the connector plug because they are over part of their length , which is not inserted into the connector, are embedded all around in a block 43 made of base plate material, which is bent at right angles from the other areas of the base plate 16. But also the ends 37 of the other switch unit 11 can not be bent unintentionally when mounting the connector, because they protrude into a frame 44 which has been made in one piece with the base plate 15 of the switch unit 11 and, as shown in FIGS. 2 and 4, a irregular, decagonal shape.
  • the base plate 15 of the switch unit 11 has a diameter d which is smaller than the diameter D of the switch unit 12 in the region of the outer surface 45 of the block 43.
  • the frame 44 is designed in such a way that it has an outer strip 46 which runs below the lower edge of the area 47 of the base plate 16 which lies to the side of the block 43.
  • the circuit board 13, as shown can be inserted with the block 43 into the frame 44, the block 43 and the frame 44 abutting one another closely in the area of the strip 46.
  • the frame 44 has a bar 48 which extends vertically up to the base plate 16.
  • the block 43 lies closely against the frame 44 over the entire height of the strip 48.
  • block 43 also fits snugly on the other, not specified, side strips of frame 44.
  • the frame 44 has a strip 49 which, viewed from the longitudinal center plane E of the housing 10, begins in front of the ends 37 of the plug contacts 33 and extends vertically downwards.
  • the frame 44 ends in the plug-in direction 38 everywhere in the same plane in front of the ends 36 and 37 of the plug contacts 34 and 33 of both switch units 12 and 11, which in turn all end in the same plane.
  • the strips 46 and 49 of the frame 44 each have at their lower ends a guide surface 50 and 51 for the connector.
  • the block 43 in which the plug contacts 34 of the circuit board 14 are injected, ends in the same plane as the base plate 15 of the second switch unit 11.
  • the frame 44 extends completely within the outer outline 53 of the housing 10. Overall, a compact switch is thus created, in which the Motor vehicle manufacturers prescribed external dimensions are not exceeded and in which the two switch units 11 and 12 can be detached from each other again easily by simply pulling the boards apart, for example for repair purposes.
