  • Circuit boards can be equipped with rotary or sliding potentiometers that convert an operator into a specific electrical resistance, as well as switches that permanently open or close certain circuits depending on the position (changeover switch).
  • Circuit boards can also be equipped with a number of buttons that close contact briefly when pressed, and with rotary encoders that convert a rotary motion into a repeated key press, the number of which corresponds to the rotational movement.
  • the key caps have a mechanical pressure point and bring in contact with an electrically conductive surface with the bare conductor tracks in contact.
  • Two foils which are provided on the inside with electrical conductors, can be glued so flat over an additional film for spacing (English Spacer) that arise at defined recesses of the spacer foil buttons that close an electrical contact when pressed.
  • membrane keys can also be equipped with mechanical key caps, which transmit pressure to the membrane keys. This construction is also common with typewriter keyboards for computers.
  • foil panels can also be equipped with force-sensitive resistors (FSR), which convert the force of the contact pressure and possibly also the position (so-called linear potentiometer) into a defined electrical resistance.
  • FSR force-sensitive resistors
  • Foil-type force sensors so far offer no tangible feedback, are therefore only very rough and have not yet acquired any significant importance.
  • Boards with potentiometers and switches are increasingly being replaced by boards with buttons and rotary encoders.
  • Membrane keyboards have become established for applications where a particularly flat design is required or where very few data inputs are required by a person (photocopiers, ATMs).
  • the invention aims an actuator provided with an electric switch for operating an electronically controlled electrical device which operates on the basis of a membrane switch, wherein the actuator is suitable to be combined with a plurality of control elements in a control panel to a functional unit with different housing shapes to create , which is flat, light, unbreakable, robust against environmental influences, such as moisture, is wear-free use and can be produced as far as possible in a controlled fully automated manufacturing process on appropriate machines.

  • the object is achieved by the features mentioned in the characterizing part of the independent claims.
  • a front panel fixes controls on a foil with membrane switches so that they remain movable for operation.
  • the underside of the controls is equipped with mechanical activators, which briefly trigger switches in the film switching element when the controls are moved.
  • a matrix circuit such as keyboards, assigns the activation of switches to the respective function of a control element.
  • control panel appears from the outside as conventional controls and switches, while the electrical properties are identical to those of keyboards.

  • a front panel 11 is mounted on the chassis 12 of an electronically controlled electrical device and secured with a conventional snap lock or screw.
  • a switching film 13 On which rest the control elements.
  • the example is a dial 14, a rotary switch 15, a slide switch 16 and a button 17.
  • the handles 14; 15; 16; 17 of these control elements protrude from the appropriate openings of the front panel 11, so that they are easily accessible for operation and movable according to the intended switching positions.
  • the handles 14; 15; 16; 17 of the adjusting elements held by protruding edges 18 under the front panel 11.
  • the handles 14; 15; 16; In the simplest case, 17 of the adjusting elements can rest loosely on a switching foil 13 which has no openings, as shown.
  • the seat of the handles 14; 15; 16; 17 of the control elements are supported by special formations of the chassis 12, conceivable would be, for example, rotatable axes for the handles 14; 15.
  • Such supporting parts of the chassis 12 may be accessible through openings in the switching film 13.
  • An activator spring 19 moves with the actuation of the respective handle 14; 15; 16; 17 of the adjusting elements and can close certain switches in the switching film 13.
  • Fig. 2 the film switch 13 is shown enlarged.
  • the structure of the layers of the film switch corresponds to that of the circuit films 13, which are installed eg in PC keyboards:
  • a base layer 21 is connected to a spacer layer 22, on which the top layer 23 is mounted.
  • the spacer layer 22 is provided at certain contact points with recesses which each form a cavity 24 there.
  • a conductor 25 on the lower base layer 23 can form an electrical contact with a further conductor track 26 on the upper layer 21, if they by an activator 27 and activator spring 19 in Fig. 1 be compressed slightly mechanically.
  • This is a technique similar to the known membrane keyboards, with the difference that the topsheet 23 is not touched directly with the finger, but is triggered by the activator 27.
  • Fig. 3 a control panel of a washing machine shown, which is constructed according to the invention.
  • a rotary control 31 a rotary switch with four positions 32, a slide switch with two positions 33 and a button 34 are present, the elements 14, 15, 16 and 17 of Fig. 1 correspond.

  • the round hole 41 serves to receive the button 34 after Fig. 3 and 17 after Fig. 1 .
  • Slide switch 33 after Fig. 3 and sliders require rectangular, elongated recesses in the front panel; 11 rotary control 14 and rotary selector switch 15 are in round openings.
  • the switch positions 51; 52 of the handles 14; 15; 16; 17 of the controls, as they are visible on the front panel 11 correspond to certain contact points on the tracks 25, 26 of the film switch 21; 22; 23; 24, 25; 26 after Fig. 2 , However, these contact points on the interconnects 25, 26 are not, as usual with boards, the switch positions assigned directly. That would be the obvious solution, which is not feasible with membrane switches.
  • the activators 27 after Fig. 2 and 19 after Fig. 1 permanently press a membrane switch
  • the elastic top layer 23 would after Fig. 2 namely deform the switching film 13.
  • the activator 27 on the film switch would not conclude a reliable permanent contact, because the spring force of the activator 27 is too weak, nor the contact would be reliably opened, if another switch position would be selected.
  • the upper layer 23 of the switch mechanically activated over a relatively long period of time would, as mentioned, deform, remain practically sticky and have an undefined electrical conductivity. That's why So far, no permanent switch of this type realized on the basis of film switches.
  • the invention utilizes the mechanical locking positions of the operating elements in order to produce a short-term mechanical and electrical contact in the intermediate states during the operating procedure. Accordingly, as in the switching position 52 after Fig. 5 recognizable, only three contact points necessary to four switching positions of the rotary switch 32 after Fig. 3 evaluate. Only during the movement of the control element individual contact points are briefly touched and closed the corresponding electrical contacts.
  • the actuated contacts act electrically like a conventional keyboard with push buttons, while the operation corresponds to the old electromechanical switches.
  • the control element and the control panel according to the invention provided with control elements can be constructed so that it can not be distinguished from a control panel with electromechanical switches during operation.
  • a plurality of switching positions 51 may be arranged in a circle or in a line, which approximately results in the operation of a rotary or sliding potentiometer. This is possible because these multiple switch positions or membrane switches are provided with a minimal mechanical detent, which is not perceived as a function of a switch. With mechanical switches this would be very difficult to achieve because they must be provided with stronger spring forces to ensure a permanent contact even with shocks.
  • Fig. 5 the contact points 51 of the rotary control 31 are after Fig. 3 and 14 to Fig. 1 displayed.
  • eleven contact points suffice to characterize twelve switch positions, wherein these switch positions have soft latching levels such that they can be moved approximately like a conventional potentiometer.
  • twelve distinctions are completely sufficient for the function.
  • the rotary selector switch 15 after Fig. 1 and 32 after Fig. 3 with the contact points 52 works in an analogous manner to the rotary switch 32 with the contact points 51, but has only four positions with a more tactile detent.
  • buttons a contact point 54 is necessary to fulfill the function.
  • the button 17 in the control panel has in contrast to the other three controls no special properties that distinguish him from known membrane keys with mechanical activator.
  • the pressure point of such buttons can be formed according to the prior art via a dome (small convex shape) in or on the film or via a spring mechanism on the key edge.
  • a possible trace layout the switching positions 51; 52 accordingly, is in Fig. 6 (upper side, view from above) and Fig. 7 (lower side, view from above) shown.
  • a thickening of the conductor track is formed by recesses of the spacer cavity 24 in Fig. 2 forms a foil switch exactly at these contact points.
  • the conductor tracks 25; 26 is isolated from the upper layer 23 and the base layer 21 by the spacer layer 22 from each other.
  • the Methods for the Construction of Such Double-Sided Flexible Circuits 25; 26 are basically known, only the layout and the application for moving activators on circuit boards are new.
  • the 4 plus 4 tracks are routed out of plug contacts 61 and can be connected to a board equipped with electronic components to interpret the data.
  • These plug contacts 61 form a flexible band, since the switching film 13 after Fig. 1 is thin and flexible and can thus save cables that would otherwise be needed to connect the control panel and motherboard of the device.
  • the invention of the operation feels like a traditional, mechanically complex actuator or of several combined in a control panel actuator with potentiometers and selector switches, but is electrically identical to a keyboard. Accordingly, existing key matrix scan modules can also be used directly for connection to the article of the invention.
  • knob 14 When knob 14 and also in the rotary selector switches 15 and slide switch 16, the handles 14; 15; 16; 17 the actuator does not permanently activate the contacts, as this - as mentioned - could damage (deform) the upper foil layer.
  • button 17 When button 17; This is already ensured by the mechanical construction according to the prior art. This is new for controls with several latching positions.
  • the perceptible during operation detent positions of the handles 14; 15; 16; 17 of the actuator are generated in the invention as in the prior art, characterized in that a rounded spring 84 after Fig. 8 to a wave-shaped counterpart 81 suppressed.
  • the spring 84 and the counterpart 81 are now with each movement of the handles 14; 15; 16; 17 the actuator moves past each other.
  • the spring drives the elevations 82; 85 and recesses of the wavy counterpart 81 from.
  • the projections force the spring to compress slightly against its spring tension.
  • the actuator comes in rest position always in the wells to stand, as in Fig. 8 shown, because the spring on each survey is not stable.
  • the invention uses precisely this effect to prevent permanent actuation of the film switches and concomitant damage to the top film layer.
  • Fig. 10 shown where the spring 84 moves straight from the survey into the recess, correspond to the surveys 102 of the counterpart 81 after Fig. 8 with the contact points 51, 52, 53, 54 after Fig. 5 and with the contact points on the tracks 25, 26 after Fig. 2 and the recesses 101 with the areas of the switching film, with the spacer film 22 after Fig. 2 are provided.
  • the mechanics of the actuators with their detent steps causes the membrane keys always close the contact only briefly and the entire switching foil works like a keyboard, although the handles 14; 15; 16; 17 of the actuators occupy fixed positions. That is new.
  • the contacts of the control elements can be summarized electrically in the form of a matrix, which drastically reduces the number of required control lines.
  • control lines could be further reduced if at each contact point ( Fig. 5 ) not only a membrane switch, but two or more membrane switches are located. Based on the sequence and size of these contacts and the resulting pulse sequences and amplitude lengths, each contact point and thus each actuation of a control element could be safely identified. This would be the 4x4 matrix of Fig. 6 and Fig. 7 reduce from eight control lines to a mere three. These three control lines would provide "Morse codes" for each position on two channels for each actuation of an element.
  • control element As hardware, the control element according to the invention or a control panel consisting of control elements for controlling only one of the known systems for keyboard scanning required. This hardware must be permanently active (even in standby mode) and initialized at initial startup by bringing all controls into a defined state.
  • This initialization can be semi-automatic by software, provided that all multiple switches with more than two positions are once operated so that at least two adjacent contact points are activated and the double sliding switches are brought into a predetermined position (about each to the right and bottom).
  • the firmware (operating software of the control panel) constantly manages an electronic image of the switch positions. This is necessary because only when changes are generated impulses.
  • the method can use a uniform program code for any control panels according to the invention, ie store the specific contact point occupancy in a table.
  • Fig. 11 is a variant of the invention to see with actuators in flat design. This variant is suitable for very small devices such as portable audio players, cameras. Here, the small size and low weight plays a special role, and also the control elements of the device during transport should not be accidentally adjusted.
  • the rotary selector switch in flat design 111 protrudes only minimally (at most 2 to 3 mm) out of the housing front panel and can therefore only be operated with a finger or the thumb. Turning the selector by touching the edge is impossible, because this deliberately flat selected.
  • the flat slide switch 112 is not actuated by lateral displacement of a protruding handle, but by a firm pressure on the top of the handle.
  • the slider 113 which, in contrast to the first-mentioned variant of the invention has no latching steps.
  • Fig. 12 is a flat control 121 to see, which is protected at the edges via a lock 122 on the front plate 123 against lateral displacement.
  • a soft spring 124 presses against the switching foil 125 away from the contact points and prevents a rattling of the handle of the actuating element in the housing.
  • the activator spring 126 does not touch the switching film 125 in the rest position, but has minimal distance to it.
  • the activator spring 126 contacts the switching foil 125 at a contact point and thus closes a circuit.
  • the latch 122 is released and allows lateral displacement. If the element is displaced laterally, the activator spring 126 can shoot different contacts according to the position of the element and thus act as a sliding or rotary switch.
  • the flat variant of the invention differs from the first described variant in that a permanent contact is not prevented by latching steps, but by the soft spring 124 in conjunction with the ability to push down each element slightly.
  • the flat design of the invention is slightly more difficult to use than the large version, because the control elements can only be touched and moved on their upper side. This can be an advantage in mobile devices, since very small designs can be realized and because accidental adjustment by the lock is impossible.
  • the flat version allows stepless regulators to be used without detents (No. 113 in Fig. 11 ).
  • a foil-shaped linear potentiometer can be used, for example based on FSR technology (force sensing resistor, force-dependent resistor). Since the activator spring always rests only briefly, overstressing the film is excluded. The continuous measurement of the position by the linear potentiometer ensures a high-resolution control option.

  • the electrical resistance in this variant depends on the position of the handle.
  • Linear potentiometers and resistor strips are otherwise a known technique. Since they were previously used only without mechanical activators, their ergonomic qualities were very limited. The visible and tactile position of such an actuator allows ease of use, which is comparable to conventional slide potentiometers; However, the invention is flatter, mechanically robust and protected by the film against contamination.

Procédé de génération d'impulsions de commutation par l'intermédiaire d'actionneurs disposés dans un pupitre de commande selon les revendications 1, 2, 8 à 15, caractérisé en ce que la poignée plate de l'actionneur (121) se déplace lors d'un actionnement sur le côté supérieur en sens inverse à la force d'un ressort (124) au minimum d'environ 0,5 à 4 mm dans la direction de la membrane de commutation (125) et en ce que pendant l'actionnement un ressort de contact (126) en fonction de la position de l'actionneur exerce une pression mécanique sur des points de contact déterminés (51 ;52 ;53 ;54) dans la membrane de commutation et en ce que des liaisons électriques respectivement différentes, spécifiques à la position entre les pistes conductrices sont produites pour actionner l'interrupteur à membrane sur ces points de contact (51 ;52 ;53 ;54) comme sur une matrice de clavier, alors que la poignée se soulève après le déblocage à nouveau dans sa position de repos d'environ 0,5 à 4 mm et ainsi après le déblocage tous les contacts électriques sont ouverts et restent ouverts.
  18. Procédé de génération d'impulsions de commutation analogiques par l'intermédiaire d'actionneurs disposés dans un pupitre de commande selon les revendications 1, 2, 8, 15 à 17, caractérisé en ce que la poignée plate de l'actionneur (121) lors d'un actionnement sur le côté supérieur se déplace en sens inverse à la force d'un ressort (124) au minimum d'environ 0,5 à 4 mm dans la direction de la membrane de commutation (125) et en ce que pendant l'actionnement un ressort de contact (126) exerce en fonction de la position de l'actionneur une pression mécanique sur des positions déterminées de la piste conductrice dans la couche supérieure de la membrane de commutation, qui produit à cet emplacement un contact électrique avec une résistance électrique en forme de bande sur la surface de la couche inférieure de la membrane de commutation et cette liaison électrique présente ainsi une résistance électrique spécifique à la position de l'actionneur, de telle sorte que l'actionneur pendant l'actionnement présente en fonction de la position de la poignée une résistance variable équivalente à un potentiomètre conventionnel, alors que la poignée après le déblocage s'élève à nouveau dans sa position de repos d'environ 0,5 à 4 mm et tous les contacts électriques sont ouverts après le déblocage.
  19. Procédé d'évaluation d'impulsions de commutation par l'intermédiaire d'actionneurs disposés dans un pupitre de commande selon la revendication 1 à 18, caractérisé en ce que un circuit intégré contrôle à tout moment la fermeture de contact sur les liaisons électriques entre les pistes conductrices, également lorsque l'appareil électronique est en repos, comme sur une matrice de clavier en séquence rapide environ 20 à 1000 fois par secondes à tour de rôle, dans lequel sur la base de l'information concernant la position précédente de la poignée de l'actionneur et le contact fermé en dernier lors d'un mouvement de la poignée, la nouvelle position de la poignée est déterminée et cette position actuelle de la poignée est écrite dans une mémoire rémanente et y est gardée disponible en vue du traitement ultérieur.
