The existing circuitry on the sensor board suitably connects the existing optical components associated with the sensing keys. Such circuitry is currently optically identifiable to identify which sensing key has been Being operated". The conductive rubber bundles the capacitive electric field lines and directs the electric field lines to the sensor circuit board, and the sensor circuit board can be disposed even at a distance from each of the sensing keys. According to the present invention, the conductive rubber has an optical passage formed in a form extending from the sensor circuit board to the sensing key. This optical channel example 200828378 can be a simple linear air passage, i.e., it can be, for example, a simple bore. However, for example, a light conductor can be inserted into the light path. The conductive rubber may be, for example, a conductive resin. Such a conductive ruthenium resin can be formed, for example, by mixing pure ruthenium with graphite. A connected light element is disposed on the sensor circuit board, which is associated with the light path in the conductive rubber. If the optical component is turned "on", when a change in electric field transfer is transmitted to the sensor circuit board by the associated sensing key, the light is transmitted to the associated sensing key. The sensing key itself is formed in a light transmissive form. The sensing key can thus receive light from the light path and be illuminated or illuminated by the received light. Thus, it is optically recognizable that the sensing key has been operated. By using a conductive rubber, the sensing key can be formed in an illuminable manner, in which case the associated sensor circuit board need not be disposed directly below the surface of the sensing key. Thus, the degree of freedom in construction can be improved. A capacitive electric field that can be transmitted by the conductive rubber can be guided outside the light path on the sensor circuit board. A second part of the object of the present invention is achieved by an electronic input unit having the features of item 5 of the scope of the patent application. The electronic input unit has a plurality of the above-described sensing keys, the advantage of which is illuminated in a connected manner. A third part of the object of the present invention is achieved by an electronic device having the features of claim 9 or 10 of the patent application. The electronic device has at least one unique sensing key that operates with capacitive electrical 200828378 field transfer and is illuminated in a connected manner, or the electronic device has an electronic input unit that includes at least one unique capacitor Sensing electric field transfer-operating sensing keys that are illuminated in a connected manner. The sensing keys that have been operated in the electronic device described above are illuminated so that it can be seen which sensing button has been operated. Further forms of the invention are described in the respective scope of the patent application, and then the electrically conductive rubber of the sensing key is compressible so that the electrically conductive rubber can be mounted in a slightly clamped manner under slight stress The sensing button is between the sensor circuit board. This has the advantage that an air gap is not formed between the sensing key and the conductive rubber, and between the conductive rubber and the sensor circuit board, since the air gap may be caused by the electric field. The phenomenon when the sensing key is transferred to the sensor board causes an adverse effect. The optical element is a light-emitting diode having a small volume, current saving, easy installation and low cost. The sensing key described above may have a metal surface made, for example, according to a physical vapor deposition (PVD) method. In this way, the electric field transferability of the sensing key pair 0 conductive rubber can be improved. On the other hand, it is possible to form a δ hai metal layer in a thin manner so that the sensing key additionally has a function of illumination. It should be noted that the 'each sensing key is provided with the metal layer insulated from each other, so that when one of the sensing keys is operated, the other key is not simultaneously operated. In another advantageous form of the invention, the plurality of sensing keys are combined into at least one unique square. This has the advantage of forming a tight 200828378 construction or forming a modular shape. This in turn has the advantage that it can be installed relatively easily. The above blocks additionally have the advantage that the blocks can be easily formed, wherein the sensing keys combined into one block are aligned with each other. Thus, such inter-arranged forms have, for example, a linear form, any desired form or a circular form. Embodiments of the invention will be described in detail below with reference to the drawings. [Embodiment] 1 A display module 1 is shown in Fig. 1 having a display area 2 and combined with a sensing key block 3. This sensing key block 3 includes a plurality of individual sensing keys 4 mounted on the associated sensor circuit board 5. Each of the sensing keys 4 has a key body 6, and the human finger can be inclined on the key body. The respective key bodies 6 of the respective sensing keys can be assembled together in a single disk-shaped housing 7. This disc-shaped outer casing 7 together with other elements for forming the sensing key 4 form a sensing key block 3 as described above. % A respective conductive rubber 8 is disposed under each of the key bodies 6 of the respective sensing keys 4, which is, for example, in the form of a respective conductive rubber block. Each of the electrically conductive rubbers 8 has a light path 9, which is for example a straight air channel, which can be achieved, for example, by a pure drilling channel. An optical element 1 is disposed on the sensor circuit board 5 with respect to a respective optical path 9, and the optical element 10 can be constituted, for example, by a so-called L E D member. The optical element 1 is connected to the sensor circuit board 5 -10- 200828378 in a switchable manner. The optical element 1 can be turned on or off by means of the sensor circuit board 5 and the circuitry configured thereon. When the change of the electric field transferability is notified to the sensor circuit board 5 and the corresponding circuit through the other elements of the optical element 1 整个 via the entire associated sense key 4, the optical element 10 is When turned on, the change in the electric field transferability is caused by the finger contacting the associated key body 6. The key body 6 is formed to be light transmissive. When the optical element 1 is turned on, the light 11 is transmitted to the associated key and body 6 by the optical path 9 of the associated conductive rubber 8. This light is received by the associated key body 6. If the key body 6 has received the light η, the key body 6 is illuminated in a visibly visible manner due to its light-transmissive nature and it can be determined that a key has been applied to the associated sensing key 4 operating. The function triggered by the above key operations is not important here. However, this function can be related, for example, to function control or to data message input. In particular, in Fig. 2, the display area 2 and the plurality of key bodies 6 of the respective sensing keys 4 " (not shown in detail in Fig. 2) can be seen. The arrangement shown in Fig. 2 as a whole forms a display module 1 having a housing surface 12 which can cover the display module 1. Thus, the display area 2 can be exposed in the outer casing surface 12. Further, each of the penetrating sections 13 of the key body 6 is applied to the outer casing surface 12. Fig. 3 shows the state in which the outer casing surface 12 has been removed in Fig. 2. As can be seen in the detail view, in addition to the display area 2 of the display module 1, there is also a sensing key block 3 having a disk-shaped outer casing 7 and its associated key body 6. -11- 200828378 Fig. 4 shows in particular the outer casing surface 12 and the sensing key block 3, each of which has a key body 6, respectively, here shown in a bottom view. Thus, the disk-shaped outer casing 7 of the sensing key block 3 can be particularly well recognized. The state of Fig. 4 is shown in Fig. 5, in which the outer casing surface 12 and the sensing key block 3 are visible. Here, the respective conductive rubbers 8 are provided in the sensing key blocks 3 of the respective sensing keys 4 for the fourth drawing. In Fig. 5, it can be seen that the light path 9 is present in each of the conductive rubbers 8 to pass the light 11 (Fig. 1). / A cut plane A-A (Fig. 6) can be seen from Fig. 7, which shows a casing surface 12. The outer casing surface 12 is made, for example, of an AB S plastic. Further, Fig. 7 shows a portion of the sensing key block 3 having the key body 6. Moreover, each of the sensing keys 4 is mounted on the sensor circuit board 5, and each of the sensing keys 4 is respectively mounted with a conductive rubber 8. The sensor circuit board 5 in particular forms a module having a sensor structure and mounted optical elements 10. The optical element 10 is directly assigned to each of the optical channels 9 of the respective sensing keys 4 or to the respective conductive rubber 8 to which they belong. The optical element 1 〇 thus directly emits the light 1 1 emitted by it to the optical channel 9 of an associated sensing key 4. The light 1 1 continues to be transmitted via the associated optical channel 9 to the underside of the other associated key body 6. When the key body 6 is in contact with a human finger, the electric field transferability is changed. The change of the electric field transferability can be via the associated sensing key 4 of the key body 6 and the conductive rubber 8 in terms of the sensing key 4 The formed path 14 is transmitted to the sensor circuit board 5. -12- 200828378 The display module 1 has a preset structural height 15 . This construction height can be, for example, 8 · 2 mm. This construction height also needs to be provided by the sensing key block 3. Therefore, the sensing key block 3 can be formed on the display area 2 with a height. Thus, the display area 2 can form the display module 1 together with the formed sensing key block 3. The above-described construction height 15 can be achieved by the conductive rubber 8 or thus the distance formed between the control surface of the associated sensing key 4 and the sensor circuit board 5 can be eliminated. The sensing key block 3 for each of the sensing keys 4 having the conductive rubber 8 can also be used as the electronic input unit 16 (Fig. 5), which acts on the change in electric field transferability, and the change in the electric field transferability has a capacitance. The role of sex is and is received and evaluated at the appropriate location and converted by the associated electronic device into corresponding various reactions.
