Definitions

  • the invention relates to a multiple switch according to the preamble of the main claim.
  • Single and multi-pole switches, changeover switches, multiple switches and. The like are known in the most varied of shapes and structures, so that, in particular with regard to the special design of a multiple switch made possible by the present invention, the comprehensive explanation of the prior art known here can be dispensed with.
  • multiple switches have in any case a manually, possibly also mechanically, for example a stepper motor, movable actuating element which acts on the position of the switching arms or carries contacts directly which move when the Actuate the actuating element with mating contacts depending on the switch position.
  • Springs can provide a corresponding pre-tension, likewise latching means are usually provided for multiple switches, for example if it is a rotary switch, in order to ensure clear switching positions during the adjustment.
  • the invention is therefore based on the object to provide a multiple switch of the type mentioned, in which a large number of switching operations can be carried out in a confined space with extremely high reliability even if some or many of these contacts are only controlled very rarely, that is works with extremely high reliability, but on the other hand is particularly inexpensive and in which the contacts to be switched are sealed against the environment, possibly also hermetically sealed.
  • the invention solves this actually contradictory task with the characterizing features of the main claim and has the advantage that a large number of single-pole switching contacts, each individually tight or completely tight against any type of aggressive media or environment, and therefore especially dustproof, kept are actuated by a common actuating element for realizing stationary switching positions, both the individual switching contacts and the further mechanical means required for actuating or controlling these switching contacts being arranged directly on a carrier plate, which is preferably a conventional printed circuit board, in the configuration and structure can be, as required by the desired switch design.
  • the invention is therefore based on the concept of the individual switch contacts, each to close or to are to be made available completely separately, so that a complete electrical isolation between the individual switch contacts is possible and, above all, the common actuating element is potential-free in all its parts.
  • the currents or voltages to be switched flow only on the circuit board from and to the individual contacts stored within their own small housing, a further considerable advantage being that such individual contact bodies, each with its own housing, are known per se and are prefabricated elsewhere are.
  • These switches are so-called miniature buttons in the form of single-pole tap keys, which include a closer and are manufactured with very small dimensions in large numbers and therefore inexpensively.
  • An easy-to-understand field of application for such single-pole typing keys is, for example, use in computing devices which have a keyboard and in which an electrical pulse signal can be generated in each case by depressing the respective keys.
  • the invention also sees in an advantageous embodiment adjacent to the individual key switches the storage of a common actuating element which rotates a rotary part acting on cams on the individual touch keys or plunger of the key switches or also a linear one cash actuator can be.
  • an intermediate storage part is provided, which is clipped in a suitable manner, for example centrally arranged to the respective key switches, in a hole or opening in the printed circuit board, which itself forms the bearing for the rotating part and further, in a further, particularly advantageous embodiment, simultaneously forms pressure transmission intermediate means (in one piece) which, preferably resiliently, but resiliently, lie between the individual typing buttons and plungers and the cams of the actuating disk, so that an action of transverse forces on the typing buttons is excluded.
  • Such transverse forces which can occur when the cam disc is rotated, are absorbed by the resilient arms of the intermediate bearing part.
  • the invention therefore makes it possible, in such a switch, the individual switch contacts of which are completely sealed, also hermetically sealed, with mutual galvanic insulation, to construct the entire switch by directly populating it on a printed circuit board, so that what is known per se in other switch designs is a kind of housing, in any case forms a main part for the switch, so that there is a decisive reduction both in the technical outlay (number of parts required, assembly effort) and in terms of the cost of such a switch.
  • the intermediate bearing part is a cylindrical basic element which only needs to be snapped into the central bore of the printed circuit board and then at the same time with integral spring arms tig the individual touch keys of the key switches covered to distract the side forces;
  • the last assembly step then consists in inserting the actual actuating element into the intermediate bearing part as a cam-reinforced rotating part and also locking it, for example with a snap ring.
  • a further preferred embodiment consists in forming the base part in a pot-shaped manner with a raised edge, with a central bore receiving the axis of the actuating element, which usually performs a rotary movement, and tongue-like pressure-transmitting means, which run in an star-shaped manner and run inwardly in a star shape, in particular via film hinges and therefore in one piece, are held, which are located between the tip keys of the key switches and the actuating cams on the encoder disk of the rotary element.
  • each pressure transmission tongue permanently assigned to its key switch has its own counter cam on its upper part and therefore the respective assigned coding disk ring with the actuating cams, the cams as a whole having inclined lateral rise surfaces for safe switching actuation and for reducing friction.
  • the friction can also be reduced by replacing the cams at least partially by rotating rollers.
  • the basic idea of the present invention is to provide for known, prefabricated single-pole toggle switches, each comprising a make contact and, due to a spring which simultaneously forms the switch contact, to provide a momentary change as direct assembly of printed circuit boards in such an arrangement that the additional arrangement of a manually or mechanically movable actuating element with its own storage and a corresponding, by this, quasi-stationary exertion of pressure on the tap keys of the key switches depending on the desired switch positions to be adopted and depending on the predetermined (rotary) position of the actuating element certain switching configurations can be achieved in a stationary manner.
  • FIG. 1 of a known, therefore prefabricated single-pole tip switch 10 includes a, usually made of plastic main carrier part 11, in which in a suitable positioning and shape simultaneously outward electrodes in the form of mounting legs for automatic assembly on circuit boards o. Like. Are inserted, which form the contacts for the single-pole closer inside.
  • a spring 13 is mounted inside the miniature key switch housing so that it, as a movable switching arm and at the same time contact element, is in the open position of the switch and is transferred by a pressure acting in the direction of arrow A into the other switching position, in which the Switch is then closed, from which switching position but due to the bias of the Spring 13 when the pressure is applied, the contacts are immediately transferred back to the starting position (switch open) by the spring preload.
  • Such a key switch is suitable for automatically populating a printed circuit board 20 shown in FIG. 2, the legs protruding downwards being passed directly through corresponding holes 21 in the printed circuit board and then being connected in an electrically conductive manner to the respective printed circuit boards on the rear side of the printed circuit board (printed circuit board side), e.g. Dip soldering.
  • the four key switches 10a, 10b, 10c and 10d provided in the multiple rotary switch 22 are arranged along a given straight line such that two of the key switches are arranged on each side of the central axis of rotation of the multiple switch.
  • an intermediate bearing part 24 is now initially seated, which is firmly connected to the circuit board 20, preferably latched, in the manner known per se, by annularly or at certain intervals over the circumference detent lugs, which at 24a, 24b are indicated, reach behind the printed circuit board rear side after inserting the intermediate bearing part and firmly anchor the intermediate bearing part to the printed circuit board 20.
  • the intermediate bearing part is essentially cylindrical with its own inner bore 25, through which the axis of rotation 26 of the actuating element is then again guided, which is generally umbrella-like, at least in the exemplary embodiment shown, and preferably integrally in an upper actuating or Coding disc 26a passes over, which then has projections or cams 28 directed towards the individual tap keys or plungers 27 of the key switches 10a, 10b, which serve to depress the plungers 27 and thus to close the contact of each key switch.
  • the actuating disc 26a as it will only be called in the following, is in a position in which the respective cams 28 are aligned with the touch keys or plunger 27 and can therefore exert the required switching pressure thereon.
  • the rotating part comprising the rotating axis 26 and the actuating disk 26a is held in the bearing bore 25 formed by the intermediate bearing part 24 in order to prevent it from slipping out in this case, for example by means of a snap ring inserted into an annular recess at 29 of the rotating axis 26. It goes without saying that other latching options are also available here.
  • a further essential feature of the present invention is that, as can already be seen from the switch structure of FIG. 2, if the actuating disk 26a is rotated, the cams 28 which apply the switching pressure would necessarily each run laterally onto the plunger 27 of the key switches 10a, 10b ... , so that there are lateral forces that can not be absorbed by all such push-button switches or their plungers.
  • a pressure transmission intermediate part 31 is provided, which, as is understood, is arranged depending on the arrangement of the key switches between the plunger 27 and the cams 28 and preferably comprises resilient cantilevers covering the plunger 27, which are secured against displacement in the xy plane are, however, in the serving serving and therefore in the drawing plane vertical z-direction are elastically or resiliently displaceable, so that any type of lateral forces are absorbed by these resilient arms. Then this can cause that when the cams 28 of the actuating disc gradually open, when the latter is rotated into a new switching position, the cams slide in a circular manner in the exemplary embodiment along the resilient arms 31a, 31b (see FIG.
  • this pressure transmission intermediate part 31 in one piece with the intermediate bearing part 24, so that it extends from its cylindrical basic shape forming the bearing for the axis of rotation 26 in the plane of the drawing in FIG its structure changes that in any case the mentioned arms 31a, 31b result, which are arranged between the cams 28 and the tappet 27.
  • the key switches can be arranged in a star shape one behind the other starting from the center, from which it can already be seen that when the respective available, available ring surface is completely filled up the circuit board 20, a considerable packing density can be achieved on individual key switches.
  • the arm that causes the pressure transmission from the intermediate bearing part in a star shape and following the basic structure of the arrangement of the key switches, starting from the hub area of the intermediate bearing part. So that the cams 28 of the actuating disk can run open, can then be arranged on both sides roof-shaped slopes on the brackets or the entire pressure transmission intermediate part can have the shape of a resilient disc.
  • a further circuit board can be arranged above the circuit board 20, the key switches of which are directed downwards with their plungers 27, in which case the actuating disc 26a can have further cams 28 pointing upwards.
  • the axis of rotation 26 of the actuating element designed as a rotating part in this multiple rotary switch can be extended on both sides, as indicated at 32a, 32b, so that actuation from both sides is possible; it is also possible to flange a gearwheel here on one of the stub axles 32a, 32b, so that the switch is mechanically rotated, for example via a Ge drives with stepper motor, a relay-operated ratchet mechanism or the like is possible.
  • a particularly preferred embodiment, which is also simple in terms of construction, for a detent still consists in the fact that by appropriately designing the cams 28 and the arms 31, 31a, 31b, for example by forming beads in the arm area, in front of and behind a detent position of the cams, a correspondingly designed cam track detent position finds and intervenes in this. This makes additional locking parts unnecessary.
  • FIG. 2 If one only starts from the arrangement, as shown in FIG. 2, in which four contacts are provided, which are formed by four individual single-position tip switch switches 10a, 10b, 10c and 10d, then only one embodiment of FIG to specify many possible, hereby at ten different locking positions, distributed over a complete 360 ° rotation angle, for example realizing a BCD code as given below:
  • the respective switching positions of the key switches 10a, 10b, 10c and 10d specified in this table are achieved by a corresponding distribution of the switching cams 28 over the lower annular disc surface of the actuating disc, it being understood that at the same time, additional switches of the same cams 28 which are not shown in the drawing, can be operated, insofar as this fits into the respective switching program sequence. These additional switches can then be arranged in a corresponding offset angular position, as already mentioned, on the same printed circuit board 20 or on additional printed circuit boards.
  • FIGS. 4-7 Another exemplary embodiment of the present invention that has been proven in practical operation is shown in FIGS. 4-7 and is explained in more detail below.
  • four key switches are also (only) provided, but these are not offset along a straight line but rather in a circular shape by 90 ° to one another, but are preferably arranged at the same distance from the center point.
  • the cantilevers of the pressure transmission intermediate part not forming tongue projections running in the direction of rotation, but starting from an outer peripheral edge of the intermediate bearing part or base part that is raised in the illustrated embodiment.
  • the one-piece base part is shown in cross-section in side view in FIG. 4 and in plan view in FIG. 5 and is designated by 40.
  • the base part 40 comprises a central hub 41, a base 42 and a raised outer edge 43 which merges upwards into a distinct, undulating curve shape 44.
  • the elevations and depressions formed by this curve form locking cams, in which one or more radially protruding from the actuating element, for example spring-loaded pressure pins, engage and thus lock and also define the angular position of the rotary switch in each switching position.
  • the pot-shaped basic shape of the intermediate storage part is also one-piece for the one again met here
  • Formation of the pressure transmission intermediate part is advantageous, which, as can best be seen from the illustration in FIG. 4 with the top view of FIG. 5, in this exemplary embodiment consisting of four inwardly projecting tongues 45, each offset by 90 °, 46, 47 and 48 is or is formed, which run from the upwardly raised edge 43 of the intermediate bearing part 40 in a star shape inwards.
  • tongues 45 to 48 are articulated in the transition to the edge, that is in their articulation area at 49, via a film hinge formed by the material of the intermediate bearing or base part itself; this transition joint zone is shown in dashed lines in FIG. 5 and also provided with the reference number 49.
  • the construction of the base part is completed in accordance with FIG. 5 by radial webs 51 connecting the hub 41 to the outer ring edge 43 in a star shape, wherein reinforcing ribs 52 which also extend radially on the bottom can also be provided in order to give the whole a correspondingly stable hold.
  • the actuation again takes place via the lower annular disk surface of the actuating disk 26a ⁇ of the rotary actuating element 26 shown in FIG. 6, the actuating cams 28 ⁇ being arranged in four separate, concentric circular paths A, B, C and D on the actuating disk 26a ⁇ and are distributed.
  • these actuating cams 28 ⁇ look down and come into operative connection with respectively assigned, separate counter cams 53, 54, 55, 56, which, opposite the actuating cams 28 ⁇ of the actuating disk 26a ⁇ and looking at them, each on one of the pressure transmission tongues 45 , 46, 47 and 48 are located.
  • the shape of the individual counter cams 53, 54, 55, 56 is shown outside the circular structure of FIG. 5, and it can be seen that these counter cams, depending on their radial distance from the center, have a different height, which is shown below with reference to the illustration 7, in which, in the compilation, but only presumably, all counter cams are shown arranged on one of the pressure transmission tongues, namely the tongue 48, so that it can also be seen that they each have a different radial position relative to one another .
  • the shape and design of the cams that is to say the counter cams and the actuating cams, is approximately the same; the cams each have a rising surface and a falling surface, as seen in the direction of rotation, so that, as can be seen in the small drawing to the right of the base part in FIG.
  • locking pins 57 directed downward from this, more precisely from the bottom 42 thereof, can engage, which engage in corresponding counter-bores in the carrier plate supporting the base or intermediate bearing part 24 and a perfect centering, but in particular also to secure against rotation.
  • the key switches are arranged on the bottom 42 of the intermediate storage part or base part 24, which of course can then itself be designed again with corresponding electrical lines, usually in the form of copper cladding on the opposite side, in order to easily and in appropriate contact connections to the push-button switches to be able to carry out one work step by soldering the tip switch switch legs.
  • the carrier plate as printed circuit board and printed circuit board on the one hand and the intermediate storage or base part 24 on the other hand merge and form a common component with both functions.
  • Such a multiple switch can also be used with particular advantage as a pulse generator, also for different directions of rotation, because by the running and running of the respective cams relative to one another, the key switches generate output voltages with a pulse-like character with continued rotary movement, with successive pulse trains for different directions of rotation, for example have a phase shift of 90 °.
  • a pulse switch is suitable, for example, as an angle encoder.
