The measures of the dependent claims can be used to usefully expand and refine the electrical devices described in the independent claims.

It is particularly advantageously possible to install at least one actuating element directly in the peripheral region of the electrical housing housing surface in particular. In this way the user can operate the at least one operating element using the fingers of the hand holding the electrical device. This advantage is particularly important for electrical devices as portable devices such as radios.

In addition, a flexible conductive plate having a switch dome in at least one operating element region is placed on the photoconductor, and the switch dome can be operated using at least one operating element, and the flexible conductive plate is at least one outside the switch dome. It has the advantage of having a popped space of.

Reference numeral 1 in Fig. 1 denotes an electric device composed of a radio. 1 shows only a part of the cross section of the radio 1 which is necessary for the present invention. The housing of the radio 1 is divided into a lower surface 70 and an upper surface 65, the lower surface 70 being interconnected with the upper surface 65 through the side 75, and the side surface being the upper surface 65. A slope is formed in the direction of the upper surface 65 in the) area, and the slope of the slope can be variously selected. This slope represents the peripheral area 45 of the housing surface 25 of the radio 15. The first conductive plate 55 is placed on the lower surface 70 of the radio 15. The photoconductor 15 is disposed opposite the lower surface 70 of the first conductive plate 55. Opposite to the first conductive plate 55, the photoconductor 15 has an assembly portion 80 composed of a recessed portion, into which the display device 5 is inserted. A window 60 is installed on the upper surface 65 of the radio 1 opposite the photoconductor 15 of the display device 5, through which the user can read the representation of the display device 5. . At the bottom of the window 60, the photoconductor 15 opposite the housing surface 25 receives a first curved portion 90 in contact with the first conducting plate 55 to receive a first light source 20 constituting a light emitting diode. )

In the peripheral area 45 there is an opening 100 for receiving the operating element 10 consisting of a button. The button 10 has a protrusion consisting of a protrusion 105 inside the radio 1, which is in contact with the housing wall from the inside when the button 10 is in an inactive state, and thus the button 10 from the radio 1. ) To prevent falling off. In the button 10 region, the photoconductor 15 is inclined in a plane substantially parallel to the peripheral region 45. On this slope of the photoconductor 15 a second conducting plate 30 is installed between the button 10 and the conductor 15, the bottom surface of which coincides with the bottom surface of the button 10 and is fitted with the photoconductor 15. A switch dome 35 having a convex portion on one side is provided in the direction of the button 10. The button 10 of FIG. 1 is in an inoperative state. When the button 10 is operated in the direction of the arrow in FIG. 1, the switch dome 35 is pressed down to contact the contact of the second conductive plate 30 in a conventional manner. The operation signal generated by the contact is transmitted to the first conductive plate 55 through the connection wiring 110 between the second conductive plate 30 and the first conductive plate 55. At this time, the first conductive plate 55 and the second conductive plate 30 constitute a common conductive plate. The second conductive plate 30 is made of a flexible conductive plate material in order to transmit the force in the direction of the arrow when operating the button 10 to the photoconductor 15 and to adapt to the shape of the light emitter 15. Operating the button 10 in the direction of the arrow will force the photoconductor 15.

After operating the button 10, ie releasing the button 10, the switch dome 35 becomes convex again and the protrusion 105 presses against the inner wall of the radio 1.

2 is a bird's eye view of the second conductive plate 30. There is a ring-shaped opening 40 around the switch dome 35 provided approximately in the middle of the second conductive plate 30. In addition, the switch dome 35 may be made of a photoconductive material.

The light rays emitted from the first light emitting diodes 20 are used for illumination of the display device 5 as well as for the illumination of the button 10 configured to transmit light at least partially through the photoconductor 15. The button 10 may be made of light transmissive silicon.

In order to improve the illumination of the button 10, the photoconductor 15 of FIG. 1 has a second, i.e. in this example, side immediately below button 10, on the side facing the first conducting plate 55. In this case, the light emitting diode may have a second curved portion 95 that may receive the light source 50. Since the second light emitting diode 50 is installed near the button 10, the illumination of the button 10 can be improved. Light rays of the first and / or second light emitting diodes 20 and 50 enter the button through the opening 40 and the switch dome 35 of the second conductive plate 30.

The display device 5 extends to the immediate vicinity of the peripheral area 45, so that the button 10 is installed near the display device 5. In the activated and non-operated state, the button 10 is placed on the photoconductor 15 through the second conductive plate 30 and the switch dome 35 so that it does not fall into the inside of the radio 1.

In addition to radios that can be used, for example, in radio or cordless telephones, the present invention applies to all other electrical devices with displays such as pagers, televisions with wires, calculators, measuring equipment and the like. For example, a light transmissive adhesive may be used to fix the second conductive plate 30 and the display device 5 to the photoconductor 15.

The button 10 may, for example, be installed between the window 60 of the upper surface 65 of the radio 1 and the peripheral area 45, in which case the button is not only installed near the peripheral area 45 but also displayed. It is installed in the immediate vicinity of the device 5 or the window 60. At this time, the expansion of the display device 5 and the window 60 is adjusted accordingly so that the button 10 and the switch dome 35 are provided below the upper surface 65 between the peripheral area 45 and the window 60. There is a sufficiently wide contact surface of the photoconductor 15 with respect to the second conducting plate 30. Second concave portion 95 of the photoconductor 15 in which the second light emitting diode 50 is accommodated in order to provide the best possible illumination to the button 10 at the installation site when the light emission of the first light emitting diode 20 is not sufficient. ) Is installed on the upper surface 65 of the radio 1.
