Definitions

  • the invention relates to a switching device of the type mentioned in the preamble of claim 1.
  • Such switching devices are used in particular in motor vehicles as multifunction switches, which have a single switch button as an actuating member.
  • This switch button can be brought into several basic positions by hand, each of which is assigned to a specific consumer arrangement. From each basic position, the switch can then be brought into one or more actuation positions by corresponding movement of the switch button, in which the consumer arrangement assigned to the relevant basic position is selectively activated.
  • such a switch can be used to selectively activate two consumer arrangements, one of which is formed by two DC motors, which are used to adjust the left vehicle exterior mirror, while the other is formed by the DC motors provided for adjusting the right exterior mirror. If you move the switch knob from one basic position to its various operating positions, the electric motors of the one outside mirror are activated for adjustment; if, on the other hand, the switch button is moved from the other basic position into its actuating positions, the other two exterior mirror motors are activated.
  • the known switching device comprises two switches assembled in a housing, which only have the actuating element in common.
  • a set of fixed contacts and a set of movable contacts are provided for each consumer arrangement to be activated.
  • Some of the fixed contacts of each set which are electrically insulated from one another, are connected to the current / voltage source, while others are connected to the various connections of the consumer arrangement assigned to this set.
  • the movable contacts of each set are combined into groups of contacts which are electrically conductively connected to one another, of which in the various actuation positions at least one is always brought into electrically conductive contact with a fixed contact which is connected to the current / voltage source, while at least one other movable contact of the same group is brought into electrically conductive contact with at least one fixed contact, which leads to the associated consumer arrangement.
  • the actuating member is always mechanically coupled to only one set of movable contacts, so that when this is moved into the different actuating positions, only this one set of movable contacts is carried along, while the other set of movable contacts is mechanically decoupled from the actuating member and therefore does not participate in its movements. Then becomes the actuator If such a switching device is transferred from one basic position to the other, the mechanical coupling to the previously actuatable set of movable contacts is released and a mechanical connection to the other set of movable contacts is established instead.
  • the invention has for its object to develop a switching device of the type mentioned so that it comprises as few items as possible and at the same time ensures trouble-free contact across a variety of switching cycles.
  • a switching device only has a single set of movable contacts which is permanently mechanically coupled to the actuating member and from this is taken into the different basic positions. Depending on the basic position from which the actuator and with it the one set of movable contacts are brought into an actuated position, the movable contacts come with fixed contacts in electrically conductive contact, which are assigned to different consumer arrangements.
  • Another advantage that results as a result of this construction of a switching device according to the invention is that the restoring forces, which on the one hand are to press the moving parts of the switching device into the new basic position when changing from one basic position to another, and also the restoring forces, which Moving moving parts of the arrangement back from an actuating position into the associated basic position, exercised by one and the same extremely simple spring arrangement can be.
  • a particular advantage of the switching device according to the invention is that it only requires the minimum number of degrees of freedom that are required to carry out the desired switching functions. It is therefore an optimum, and the manufacturing costs are significantly lower than with conventional switches with comparable switching functions.
  • the flat fixed contacts 6 to 12 are located on this surface 3, e.g. can be produced by the known photolithographic etching process.
  • the bare conductor surfaces of these fixed contacts 6 to 12 pointing towards the viewer are raised by hatching lines from the non-conductive areas of the printed circuit board side which electrically insulate the fixed contacts 6 to 12 from each other.

This means that such connecting lines 14 to 22 and 41 to 46 are only in electrically conductive connection with one another at such intersection or contact points which are highlighted by a circular thickening. The same also applies to the connection points at which the connecting lines 14 to 22 and 41 to 46 are in electrically conductive connection with the fixed contacts 6 to 12. These connection points do not necessarily have to be at the locations shown in FIGS. 1 to 8. These places were chosen in such a way that a simple representation of the interconnects results. In practice, these points will be positioned so that they do not hinder contact between the fixed contacts 6 to 12 and the movable contacts 30.
  • connecting lines 14 to 22 and 41 to 46 in the practical embodiments are not in the surface 3 of the fixed contacts 6 to 12.
  • the movable contacts 30 can also move over such insulating areas without the risk of a short circuit, in which connecting lines 14 to 22 and 41 to 46 are shown in FIGS. 1 to 8.
  • This can be implemented, for example, in such a way that the connecting lines 14 to 22 and 41 to 46 are located on the underside of the printed circuit board 5, on the top of which the fixed contacts 6 to 12 are arranged.
  • the electrically conductive connection between the fixed Contacts 6 to 12 and the connecting lines 14 to 22 or 41 to 46 are then produced in the usual manner by plated-through holes.

It should be expressly emphasized that these axes 32, 33 have no specific technical function; they are purely fictitious and are used for explanatory purposes only.
  • each fixed contact arrangement shown in FIGS. 1 to 8 is formed by three, approximately strip-shaped, fixed contacts 6 which run parallel to one another and at an angle of 45 ° to the axes 32, 33 from "top left” to “bottom right", 7, 7, of which one (contact 6) is electrically conductively connected to the “plus” pole of a DC voltage source (likewise not shown) via connecting lines (not shown), while the two contacts 7, 7 are connected to one another via one or two connecting lines 14 and are connected in an electrically conductive manner to the “minus” pole of the direct voltage source via a connecting line (not shown).

  • the fixed contact 8 is formed directly as a cross with bars of equal length and electrically connected to one another.

  • the second consumer arrangement shown in FIG. 6 is again formed by two DC motors 47, 48, which e.g. serve to adjust the right wing mirror of the same motor vehicle and to enable the modes of operation just described with the two "left” and “right” groups of fixed contacts 8, 9, 10 of FIGS. 1 to 6 arranged with the aid of the connecting lines 41 to 46 are connected.
  • the connections of the connecting lines 41 to 46 are modified compared to the connections of the connecting lines 15 to 20 so that the same operating conditions result for the second consumer group as for the first consumer group, if the actuating member and with it the set of movable contacts 30 from the the basic position assigned to the second consumer group can be shifted out to "up", "down", "left” or "right".
  • the switch device shown in FIGS. 1 to 6 has a single set of six movable contacts 30, which are combined into two contact groups, each of which comprises three movable contacts 30.
  • These mechanically movable contacts 30 are symbolized in FIGS. 1 to 6 (and also in FIGS. 8 and 9) by small filled circles which are connected to one another in groups by electrically conductive connecting webs 31. It is essential that only the movable contacts 30 rest on the bare conductor surfaces of the fixed contacts 6 to 12 and can come into electrical contact with them.
  • the connecting webs 31 are located outside the surface 3 of the fixed contacts 6 to 12 and can therefore cross them over without coming into electrical contact with them.
