Definitions

  • the invention relates to a small electrical switch for installation in a lock, especially a tailgate lock of a motor vehicle, with a switch housing, with an actuator on which a movable part of the Lock engages, with the first moved by the actuator Contact elements, with stationary in the switch housing arranged second contact elements by movement of the first contact element optionally electrically with each other are conductively connectable, and with plug connections to the stationary second contact elements, such as e.g. from the DE-U-83 17 080 known.
  • Small electrical switches of this type must have a space requirement are so limited that they are still in a lock, especially the tailgate lock one Motor vehicle can be installed. In the latter case the switch should normally open when the lock is opened a lighting of the trunk (trunk) and / or Trigger the anti-theft device. These functions are difficult at the same time space-saving, reliable and with The smallest possible manufacturing effort in a small switch to accommodate.
  • the invention has for its object a generic to improve electrical small switches so that the switching functions in the switch save space and are reliable can be accommodated and the switch can be produced with extremely little effort.
  • the Actuator a slidable in the switch housing Carriage is, of which at least as the first contact elements two resilient contact tongues come off that the stationary second contact elements consist of profile parts, which go into one piece in the plug connections, and that the profile parts to achieve different contact times accordingly bent at different angles Have surfaces on which the contact tongues engage.
  • an electric Small switch 1 is made up of two detachable housing parts 2, 3 existing switch housing.
  • the housing housing part 2
  • the carriage 6 is through the Coil spring 5 in Figures 1 and 2 biased to the left.
  • From the carriage 6 is a pin 7 through a slot 8 in Housing part 3 from the outside. Intervenes at pin 7 (not shown) part of a castle, in which the Switch 1 is installed.
  • the lock is closed the carriage 6 over the pin 7 against the effect the spring 5 in its right in Figures 1 and 2 Starting position held.
  • the spring 5 pushes the carriage 6 out of its starting position in the end position shown in Figures 1 and 2.
  • the spring 5 could also be omitted if the Carriage 6 by the opening and closing movement of a Key is inevitably taken.
  • the same as the housing part 3 electrically insulating plastic is manufactured as stationary second contact elements profile parts in shape of profile wires 22, 23, 24, which, like in particular from Figure 1 to achieve different Contact points differ accordingly are bent at right angles, so that on their top Correspondingly bent contact surfaces for the contact tongues 12, 13, 14 arise.
  • the profile wires 22, 23, 24 have one in the illustrated embodiment right-angled cross-section, but others can also Cross-sectional shapes are used.
  • bent areas 25, 26, 27 of the made of electrically conductive material 22, 23, 24 can with appropriate position of the slide 7 with the free ends of the resilient contact tongues 12, 13 and 14 come into electrically conductive connection.
  • the ends of the profile wires on the right in FIGS. 1 and 2 22, 23, 24 go in one piece and without changing the Profile cross section in plug connections 32, 33 and 34 over, with which via corresponding sockets electrical connection lines can be connected.
  • the bent Profile wires 22, 23 and 24 with their integrally attached Plug connections 32, 33, 34 can be extremely easy to manufacture and space-saving in the housing part 2 insert firmly.
  • the described small switch 1 works in the following Wise:
  • the lock is in the closed state Slider 6 and equipped with the contact tongues 12, 13, 14 Contact plate 9 in their right in Figures 1 and 2 starting position, in which the coil spring 5 is excited.
  • the contact tongue lies in this position 12 on the area 25 of the profiled wire 22, which is a zero or Is ground wire.
  • the contact tongues 13, 14 make due the correspondingly short regions 26, 27 the profile wires 23, 24 have no contact with these profile wires, rather, they stand freely in the housing.
  • the contact tongues move 12, 13, 14 in Figures 1 and 2 to the left.
  • the profile wire serving as neutral or earth conductor 22 and the associated tongue 12 can also omitted if the contact tongues 13, 14 in a different way are permanently connected to ground or a zero pole. It is of course also possible with the described Switch to switch only a single circuit for example over the profiled wire 23. In this case can the profile wire 24 and possibly also the profile wire 22 omitted.
  • Figures 4 and 5 show similar to Fig. 2 and 3 sectional views a modified embodiment of a small switch 40, in its basic construction and function that described with reference to FIGS. 1 to 3 Small switch 10 corresponds.
  • the same or corresponding to each other Parts are in Fig. 1 to 3 or 4 and 5, respectively provided with the same reference numerals.
  • the only difference between the two small switches 10 and 40 consists of training as a stationary second contact elements acting profile parts in the Small switch 10 according to FIGS. 1 to 3 as profile wires 22, 23, 24 are formed in the embodiment according to FIG. 4, 5, however, the shape of profiled sheets 42, 43 and 44 to have. With the correspondingly different essentially surfaces of these profiled sheets which are stepped at right angles act as the first contact elements Contact tongues 12, 13 and 14 together. So that corresponds the operation of the small switch 40 exactly that the small switch 10.
  • the profile sheets 42, 43, 44 e.g. as stamped parts or die-cast parts (especially made of zinc alloy) are particularly easy to manufacture and otherwise in the simplest way on the housing (housing part 2) Small switch 40 can be attached.
  • the profiled sheets 42, 43, 44 in correspondingly shaped Slits inserted into the lower housing part 2, after which the ends are pried open in a manner known per se, so that spread ends 45, 46 arise through which the profile sheets 42, 43, 44 are held in place.
  • the profiled sheets 43, 43, 44 run on one side in one piece in plug connections 52, which are the plug connections 32, 33, 34 (Fig. 1) of the small switch 1 correspond. Also in the area of these plug connections the profile plates 42, 43, 44 by caulking in the housing part 2 attached. This is indicated in Fig. 4, in which shows a caulking tool 55 in dash-dotted lines is with a shoulder in the area of the Plug connection 52 an expansion 56 can be produced, through which the relevant profiled sheet 43 also in the area of the plug connection 52 firmly anchored in the housing part 2 is.
