ste 11 is formed. The condenser plates 12, 12 'are also excited by the mains alternating current, two separate condenser plates 13 and 14 or 13', respectively, and as a result the cistern valve is raised by lifting the flushing valve.

that are, and from which the other plates 14 and 14 'as long as the solenoid 21 is energized, water flows out of each other and via a further line 16 to the cistern. As soon as the value circuit 9 connected by the relevant timer. has elapsed for a certain time, the relay coil 19 is energized via two connecting lines 17, 17 ′ to the outlets and the relay contact 20 opens. As a result, the control circuit 10 connected to the value circuit 9 also contains no current in the solenoid coil 21, so that the flushing set falls back two timing elements (not shown in detail), the delay and flushing of which are timed by closing the cistern valve by means of an adjustable resistor 18 or 18 ' det. The Wi-Fi can be preselected by setting it accordingly. At the output of the control circuit of the states 18 and 18 'it can be achieved that when the 10 is touched, a relay track 19 is connected, which is also connected to a capacitor plate 12 of the sensor buttons 11, a full secondary winding 6 of the transformer 3. permanent emptying of the cistern and when touching the on-on of the relay coil 19 associated as a closer capacitor plate 12 'only partial emptying of the relay contact 20 is provided, a magnetic cistern is carried out. Here, the two flushing times for the coil 21 of a cistern valve are to be switched on or off, taking into account all conditions (size of the cistern - in the case of the magnetic coil 21 for excitation by the network change 20 content, emptying speed, size of the desired voltage and thus, likewise via the plug contact flushing water volume), for example, between 22 and 30 s, via the relay contact 22 with the mains plug contact. It should also be mentioned that a short touch to one of the ten 5 is connected. Touch fields, i.e. one of the capacitor plates 12 and 12 ', with further properties of the evaluation circuit 9 and one finger is sufficient, since the time during which the relay control circuit 10 remains energized by means of the radio coil 19 below is described by the corresponding timing element of the control device shown is determined as a function of whether the touch surface is illuminated by the. affected person remains touched or released

The evaluation circuit 9 is designed for this purpose, on the one hand.

2 and 3, an embodiment of the sensor mode 200 ms is shown via the line 16 to the sensor key 11 30 key 11. This has a glass ceramic best-to-deliver and, on the other hand, to determine whether the intestine returned via the plate 25, which is very break-resistant and also very sortaste 11 and the lines 15 and 15 ', so that no current is transferred the user to earth pulse are unadulterated. The capacitor plates 14, 12 and can flow and therefore also sensitive patients, e.g. 12, 13 and 14 ', 12' and 12 ', 13' each form two in series, such with pacemakers, are absolutely safe. The switched capacitors, so that there is normally a pulse of metal coatings 12 provided as touch fields on the outside or in contact with line 16 on the outside or contact side with line 16. for evaluation and 12 '(Fig. 2), which the capacitor plates 12 circuit 9 comes back. To form such an undistorted and 12 'of FIG. 1. The metal coatings 12, 12 'returning pulse speaks the evaluation circuit 9 are not provided with symbols 26 or 26', which respond to a large, so that no further processes are triggered. 40 or a small amount of rinse water. On the back

If one person is one or the other of the touch plate, the glass plate 25 with further metal coatings 13,

provided capacitor plates 12 or 12 'short- 14, 13' and 14 '(Fig. 3), of which the metal coating

As a result, part of the pulse power is led to earth, so 14 'thus form capacitor plates 13, 14, 13', 14 'of FIG.

plate 12 or 12 'of returned pulse in its amplified contact springs to which the lines 15, 15' and 16

tude is falsified. The evaluation circuit 9 recognizes that are connected in FIG. 1. Holes 28 (FIG. 2) serve to distort the amplitude of the pulse and in this case, when the glass plate 25 is fastened to one of its output lines 17, 17 '(not shown), gives a pulse-shaped Si carrier or cover plate by means of screws.

depending on whether the falsified pulse has returned via the line 55 In FIG. 4, an exemplary installation of the present device 15 or the line 15 'has returned, i.e. whether the per-control device in a sanitary facility has touched the capacitor plate 12 or 12 'in one person. Recess of a wall 30 recessed cistern 31st

As already mentioned, the control circuit 10 contains two shown. In a known manner, an electromagnetically independent cistern valve 32 is arranged in the cistern, independently of one another by means of the resistors 18, 18 ', of which adjustable timer elements, the one timer element being connected to a 60 in FIG. 4 with only its upper part with an interconnected electrode Line 17 arriving output pulse of the evaluation magnet 33 is shown. The valve 32 used differentiation circuit 9 and the other by one on the line 17 'detects from known valves of this type, such as those e.g. is triggered from the incoming output pulse. The control of the CH-PS 505 262 are known, only in that it does not include a circuit 10 which also has an electronic switch which switches a float to keep the valve open until one of the timers is triggered completely and when the timer is completely emptied Cistern has, since, as already explained the sequence of those caused by the relevant timing element, the closing of the valve is switched off by switching off the time delay. In the switched-on electromagnet before the flushing of this switch, this should be possible from the secondary winding 6 of the switch. It is also known that an

cover plate or so-called revision plate 34 a wall breakthrough. 35 covers, the plate 34 can be removed by loosening screws 36 to provide access to the valve 32.

On the cover plate 34, the glass plate 25 previously described with reference to FIGS. 2 and 3 and indicated in FIG. 4 is fastened in a splash-proof manner together with a circuit housing 37 as a sensor key. The circuit housing 37 contains all parts of FIG. 1 on the low-current side, including the power transformer 3. In FIG. 5, the rear view of the circuit housing 37 is shown with the housing cover removed. It can be seen from this that in the housing 37, e.g. on a circuit board, the transformer 3, the relay containing the relay coil 19 and the relay contact 20 and an encapsulated unit 38 with the evaluation circuit 9 and the control circuit 10 are arranged, the axes 39, 39 'of the two adjustable resistors 18 being accessible when the housing cover is removed , 18 'of the control circuit 10 are indicated. The interference protection filter 7 and the power supply circuit 10 of FIG. 1 are not shown in FIG. 5,

however, also housed inside the housing 37. 5 also shows one of two holes 40 for fastening the cover plate 34 over the wall opening 35 by means of the screws 36 (FIG. 4). For electrical connection of the housing 37 to the AC network and the solenoid 21 of the valve, the plug contacts 5 and 22 (FIG. 1) are arranged on the housing 37.

The present control device can thus only be assembled by changing or supplementing the cover plate 34 by means of the OK sensor button 11 and the associated components contained in the circuit housing 37 with an electromagnetically actuated flushing system which is arranged under plaster. Of course, it is also possible to arrange the cover plate 34 or a similar plate together with the sensor 15 key 11 and the circuit housing 37 on an open cistern. It is also possible to control a water supply other than the flushing water supply for a toilet bowl in the manner described, if necessary also with more than two touch fields for 20 different amounts of water.
