Description

Switch unit

The invention relates to a switch unit with at least one base part.

Switch units are known in the art. These serve the switching on and off of devices and devices, in particular in the form of light switches for switching on and off of light sources

Room lighting. It happens that conventional light switches upon entering a dark room are not immediately found, but rather cumbersome after this, before the room lighting can be turned on. As a temporary light, a light source is partially plugged into a socket near the door, so that you can possibly find the light switch by the low light that emits this auxiliary light. However, if such a temporary light is not provided, when entering dark rooms there is the problem that the light switch is badly located.

The present invention is therefore an object of the invention to solve this problem, that is, an easy findability of a switch unit, in particular a light switch, regardless of the lighting conditions in the room that is entered to allow.

The object is achieved by a switch unit according to claim 1, characterized in that at least one with respect to the base member movably arranged switch presence detector unit is provided with presence detector and pressure switch functionality. Further developments of the invention are in the dependent

Claims defined.

This creates a combination of a presence or motion detector and a switch element as a switch presence detector unit, which has the advantages of a presence or motion detector with the advantages of a

Switch linked. The switch presence detector unit is movably disposed opposite to the base portion of the switch unit to initiate a switching operation upon movement of the switch presence detector unit. The base part of the switch unit can be the power part of this, for example is stationarily arranged and fixed in a room wall. this

stationary part opposite is the switch presence detector unit as

Actuator of the switch unit movably arranged. The mobility can be allowed to a small extent, for example limited by a few mm, such as 1 to 2 mm. To trigger a switching operation of the switch presence detector unit is in particular at least one switch contact

intended. To reset the switch presence detector unit to its home position prior to actuation, one or more

Reset elements, such as spring elements, be provided.

In addition to manually actuating the at least one switch contact, the switch presence detector unit can also be used to automatically switch on at least one first light source of room lighting and / or one or more visual and / or acoustic signals for easy locating

At least upon detection of the presence and / or movement of a person in the detection area of the switch unit, the switch unit emits a switch unit, whereby the person quickly finds the switch for switching on the first light source even in dark rooms. The switch presence detector unit may comprise at least one infrared presence or motion detector sensor element, wherein the heat radiation from persons or other heat sources, such as

For example, animals, which is in the detection or

Move the detection range of a sensor element.

The presence or motion detector part is thus with a

Pressure switch functionality provided, which means that when exerted a compressive force on the switch presence detector unit, this moves and thus trigger a switching operation like a conventional pressure switch or button. A button also has a push-button functionality. The switch presence detector unit thus has a pressure switch or

Button function on. Upon entering a room can be done in a conventional manner actuation of the switch.

Advantageously, at least one lens unit is provided with at least one light source for backlighting the lens unit in order to provide a status display, which can indicate the operating state of the switch unit. Such

Rear lights can also facilitate locating the switch unit. By backlighting with differently colored light-emitting diodes (LEDs), the functional state of the switch can be displayed, e.g. through a red and a green LED.

Furthermore, at least one light source in the switch unit is advantageously provided, which radiates light in a room, in particular downwards in the direction of the floor, and represents an optical signal for locating the switch unit. This light source in the switch unit is hereinafter referred to as a second light source, for distinguishing from the at least one light source of a room lighting, which is referred to as the first light source. However, it can also be a brightness-dependent and / or dependent on the presence of a presence or movement signal control of the first light source

Room lighting and / or the second light source can be provided. If a movement, for example opening of a room door and / or the presence of a person in the room, is detected when providing a presence signal or movement signal-dependent control by the at least one sensor element, the at least one second light source can advantageously be switched on, which is advantageous in the lens unit or is arranged at least in the region of the lens unit or alternatively or additionally in a frame or

Frame part of the switch unit can be arranged.

Advantageously, at least one device is provided for adjusting one or more light intensities of the at least one second light source, wherein the selection from the set of set light intensities can be effected by a control unit. The values of the luminous intensities which can be selected via the control unit can be adjusted by means of adjustment devices, such as potentiometers. By setting the number of luminous intensity values, there will be a set of selectable luminous intensity values from which the control unit will make an appropriate choice according to the desired mode in which the switch unit is to operate or operate, eg, the nightlight or orientation light mode can meet. Furthermore, by an advantageously provided brightness sensor, the ambient brightness in the space surrounding the switch unit, the by the at least one first light source (room lighting), controlled by the control unit cooperating with the switch unit, to be illuminated, detected and with a predetermined or predetermined

Twilight threshold can be compared. If the ambient brightness in the room falls below the predetermined twilight threshold, then the at least one second light source can be activated to emit light. Will one

Movement or the presence of a person detected in the room, so the at least one second light source of a first predetermined or

predetermined light intensity or light intensity to a second predetermined or predetermined light intensity or light intensity, e.g. higher than the first one, switch. The second intensity of light may also be less than or equal to the first intensity or intensity. Furthermore, upon detecting a movement or the presence of a person in the room, the at least one second light source can be switched off and the provided at least one first light source (main room lighting) can be switched on. Even without detection of a movement or presence of a person in the room, upon detection of decreasing ambient brightness in the surroundings of the switch unit, the at least one second light source with a first light intensity or

Light intensity through the switch presence detector unit or the

Brightness sensor are triggered. As a result, the switch presence detector unit even without detecting a movement in space at decreasing

Ambient brightness in the room can easily be found by a person entering the room.

The lens unit is translucent or transparent to allow passage of light to detect the movement or presence of a person in the room.

For detecting the ambient light in the vicinity of the switch unit, the switch presence detector unit advantageously comprises at least one

Brightness sensor. To protect it from light from the light emitted by the at least one light source of the lens unit, the light is

Brightness sensor advantageously within a housing of the switch presence detector unit by a device opposite to that of the at least one light emitting or transmitting light protected or arranged shadowed or shaded. The device can be a reflector, wherein the brightness sensor is arranged on a side of the reflector facing away from the at least one light-emitting means, so that the at least one brightness sensor is hidden behind or below the reflector in a contact that can be brought into contact with the environment of the switch unit Area can be arranged. That of the at least one light source

emitted light can not be detected by the brightness sensor thereby substantially or the light emitted by the at least one light source is not detected by the brightness sensor as ambient light.

For example, the at least one brightness sensor in the interior of the switch presence detector unit, in particular in the lens unit, arranged below the particular tapered surfaces of the reflector, ie on the side facing away from the reflector, and only over

Light channels or even in the arrangement region of the brightness sensors translucent lens unit with the outside of the switch unit, so the environment of this, in conjunction, so that stray light from the

Brightness sensor can be kept away. In this way, it can be ensured that the light conditions actually prevailing in the room are detected and the decision regarding the possible switching on of the at least one second light source for the identification of the switch element or of the

Switch unit is based.

In addition to providing the at least one light source for backlighting the lens unit in the switch presence detector unit for displaying the

Operating state, the at least one second light source and for this at least one of these associated light exit opening may be provided. The at least one second light source is advantageously designed as a so-called downlight, that is to illuminate one in the installed state below the

Switch unit arranged area of a room. Accordingly, the light exit opening is advantageously provided on the underside of the switch presence detector unit when arranging the switch unit in the installed position in a room, ie in particular when mounted on a room wall. In order to set the targeted light emission only over a predetermined angular range or provide, the at least one second light source in one with the

Be arranged light emission opening housing. As a result, a light propagation in the switch presence detector unit can be avoided and the light propagation can be focused and shaped specifically. By providing a surrounding the second light source housing, which is also provided with a light exit opening to allow light to escape from this, on the one hand a scattering of light of the second light source in the interior of the switch presence detector unit and thus in the field Lens unit can be avoided. On the other hand, through the housing and its

Light exit opening in conjunction with the light exit opening, which is provided in the switch presence detector unit, the light exit angle of the second light source can be set specifically.

The light exit opening on the housing surrounding the second light source can be covered by a transparent or translucent cap or cover, wherein the cover can also be colored in order to allow a colored light exit. The second light source is advantageously used as night and / or orientation light and is directed at arranging the switch unit in particular on a room wall down to avoid dazzling of people in the room.

The at least one second light source is in particular at least one

LED (LED). In particular, two LEDs are provided. The light color can be, for example, 3000 Kelvin. The at least one second light source may be disposed symmetrically with respect to the housing of the switch presence detector unit with respect to the central axis thereof to permit symmetrical light exit of the light cone emitted by the second light source with respect to the switch unit. Basically, however, an asymmetrical arrangement is possible.

The at least one second light source can be made dimmable and one

Device to be provided for dimming. Such a dimming, ie changing the brightness, can be controlled, for example by pressing a button etc., also remotely controlled. This makes it possible, the respective light source first with only low brightness, so a predetermined or predetermined first intensity or intensity to bring to light, for example, for permanent operation in detecting a loss of brightness, so one

Falling below a predetermined or predefinable

Twilight threshold, in the vicinity of the switch unit, as at dawn and darkness. Is by the at least one sensor element, a movement in space and / or the presence of a

Person / heat source detected, the second light source can be another

Deliver or emit light quantity with a second predeterminable or predetermined light intensity or intensity, that is, preferably shine brighter.

Upon detection of a presence and / or movement of a person in the room, the at least one second light source may remain switched on, that is to illuminate with the second light intensity or intensity. As soon as no more movement and / or presence of a person in the room is detected, the at least one second light source can be switched off again after a possible adjustable delay time, that is, again with the first light intensity or

intensity shine.

The room lighting of a room, ie the at least one first light source, can be achieved by manually actuating the switch presence detector unit

be turned on. Furthermore, it is possible, despite detecting the presence / presence of a person in the room by the at least one

Sensor element no actuation of the switch-presence detector unit is made to automatically turn on the room lighting, so the at least one first light source. Turning on the at least one first light source

(Room lighting) can thus be controlled manually by pressing the switch presence detector unit. Additionally or alternatively, due to the detection of a presence and / or movement signal by the at least one sensor element of the switch unit, the at least one first light source (room lighting) automatically, possibly also dimmed, are turned on. By switching on the at least one first light source (room lighting), be it automatically or manually, the at least a second light source are turned off. This can also be done automatically abruptly or under dimming.

The switch presence detector unit thus comprises on the one hand the at least one sensor element for presence and / or movement detection and on the other hand the at least one brightness sensor for detecting the ambient brightness in the surroundings of the switch unit, so that on the one hand the at least one second light source can be controlled and on the other hand a dimming or

Switching the at least one first light source (room lighting) is made possible according to the detected signal of the at least one sensor element. The at least one second light source can permanently light with a comparatively low brightness, which preferably corresponds to the first light intensity, and serve as so-called night light, or with a greater brightness, which preferably corresponds to the second light intensity, and serve as a so-called orientation light , Furthermore, the at least one second light source of the switch presence detector unit can only be switched on if the at least one sensor element perceives a decreasing brightness in the room and / or a presence and / or movement of a person in the room, so that the room entering person can find the switch unit and press. If the switch element is not actuated, upon further detected presence and / or movement of the person in the room through the sensor element, a signal for switching on the at least one first light source (room lighting) can be delivered or through the

Evaluation of a control unit, the presence and / or movement signal that is detected at the sensor element, for switching on the room lighting by the control unit and no longer detected presence signal and / or motion signal to turn off the at least one first

Light source (room lighting) can be used. Turning off the at least one first light source (room lighting) can with a

specifiable overrun time.

The lens unit can be chosen differently with respect to its detection range, for example, a flattened or hemisphere lens can be used, which is a semicircular in the wall mounting of the switch unit Detection range allows. Other lens forms and lens optics, for example Fresnel lenses, may also be used.

Further advantageously, at least one rechargeable energy store for supplying the sensor element for movement or presence detection and / or the second light source can be provided with power in the switch unit. The at least one rechargeable energy store can be designed as a modular unit and be provided with at least one connection means for insertion into the switch unit and connecting to the

Sensor element and / or the second light source. By arranging the rechargeable energy storage, in particular accumulators, as

Module unit in the switch unit is an easy insertion and removal possible. Advantageously, this module unit is arranged in the housing of the switch unit in a frame element in order to protect the at least one rechargeable energy store, which is arranged on a corresponding board against mechanical attacks and spatially separate from the or the other electronic components of the switch unit, wherein the module unit comprising the at least one rechargeable energy store advantageously between the front side switch presence detector unit cover, which comprises the at least one lens unit, and electronic components for

Control of the switch unit is arranged.

By the modular units of the switch unit spring elements can also extend, which serve the resilient provision of the switch presence detector unit in training as a button.

FIG. 1 shows a plan view of a switch unit 1. This comprises a switch presence detector unit 10. This is sketched in detail in FIG. It may be angular in plan, as indicated in Figure 1, or round. Other shapes are possible. The switch presence detector unit 10 is, as Figure 1 and Figure 3 can be seen, inserted into a frame 1 of the switch unit 1. It protrudes beyond its outer surface 19, as the side view of the switch unit 1 in Figure 3 can be removed. When installing the switch unit 1 in a direction indicated in Figure 3 room wall W of the frame 11 can be countered therein on a metal frame and a arranged in the room wall W part 80 of the switch unit 1 in a box 81 in the room wall W and a housing 17. The part 80 comprises the power part of the switch unit, thus the shading of the switch unit 1, and a control unit 8, which is arranged in the switch presence detector unit 10. Part 80 is fixed or

arranged stationary in the wall W, while the frame 11 rests on this and the switch occupancy detector unit 10 at least partially protrudes from this or this (see Figure 3) and is movable relative to the part 80 and the housing 17. By providing this mobility, the switch occupancy detector unit 10 receives its switch functionality, thereby becoming the Switch. To trigger a switching of at least one first light source 9 of a room lighting, at least one contact switch may be provided on the movable switch presence detector unit 10, as in FIG. 3

When moving, in particular moving, the switch occupancy detector unit 10 comes into contact with the contact switches 130, actuates them, and the contact switches trigger a switching operation in the at least one light source of the room lighting 9. The control unit 8 for controlling the switching operations is connected via a connection 18 to at least one light source of the room lighting 9. The connection 18 may be in the form of a cable and / or as a radio link or otherwise formed and is indicated in Figure 3 by a dashed line.

The switch presence detector unit 10 has a lens unit 13. This is flanked by a first cover member 12 and a second cover member 14 on two sides, that is arranged between the two cover members 12, 14, as Figure 1 can be seen. However, the arrangement can also be varied. The lens unit 13 is exemplarily elongated rectangular and narrower than the two cover members 12, 14. To a Lichtbzw. To allow radiation passage, the lens unit 13 is translucent, in particular translucent or opaque, may also be transparent. The two cover elements 12, 14 are not translucent. The lens unit 13 is provided with a reflector element 3. In its center, a sensor element 4 is arranged. In order to allow a beam entry in the direction of the sensor element 4, the lens unit 13

especially permeable to infrared rays when the sensor element 4 is designed to detect the presence of a person in a room via infrared radiation measurement. The reflector element 3 is conical in

Direction of the sensor element 4 formed tapered.

The lens unit 13 comprises one or more lenses, in particular may be provided with Fresnel lenses. The provision of Fresnel lenses is particularly suitable because with a comparatively flat design short focal lengths and a high light or radiation incidence yield are possible. The

Sensor element 4, in particular infrared sensor element, is inside the Switch presence detector unit 10 recorded. The sensor element 4 detects presence signals and motion signals. To detect the brightness in the vicinity of the switch unit 1, two brightness sensors 5 are provided by way of example. These are, as can be seen in FIG. 1, arranged on two opposite sides 110, 111 within the lens unit 13 below the tapered surfaces of the reflector element 3. In the cross-sectional view shown in FIG. 2, two of the brightness sensors 5 are indicated. These are due to their arrangement below the conical surfaces of the

Reflector element 3 against stray radiation of light-emitting diodes 6, which are arranged in the region of the lens unit 13, protected because the reflector element 3 directs the outgoing light emitting diodes 6 beams only in the frontal region 112 of the lens unit 13. An incidence of stray light from the LEDs to the brightness sensors 5 can be avoided, it is only a lateral light incident on the brightness sensors 5 is provided, which is indicated by the arrows P1 and P2 in Figure 2.

In the interior of the switch presence detector unit 10 in the region of the lens unit 13, the number of light-emitting diodes 6 as a light source for displaying the

Operating state of the switch presence detector unit arranged. These are, as indicated in Figures 1 and 2, arranged on a circuit board 7 and approximately parallel or perpendicular to the outer surface 15 of the lens unit 13 on a side wall 16 thereof. The LEDs 6 are substantially flat

formed so that they only slightly into the interior 114 of the lens unit 13 protrude. The light-emitting diodes 6 can be configured to display the operating state as red and green light-emitting diodes. Like the sketchy one

Cross-sectional view of the switch presence detector unit 10 can be seen in Figure 2, the brightness sensors 5, as already mentioned, by the reflector element 3 from the light-emitting diodes 6 sealed off, so that the

Brightness sensors 5 are shaded thereby, thus decoupling provided by the light emitting diodes 6 emitted light and scattered light is thereby provided.

The function and operation of the switch unit 1 can via the

Control unit 8 are controlled, in particular in the switch Presence detector unit 10 and here for example in the housing 17 of the switch unit 1 is arranged, but can also be arranged outside of this, in particular at a central location of the room or a building and / or in the region of a light source of room lighting 9. About the

Control unit 8 is a switching on and off of the room lighting 9 of the room and / or individual light sources of the room lighting 9 possible. The room lighting 9 is merely indicated in FIG. 3 and may comprise a number of light sources, which are usually arranged remotely from the switch unit 1 at one or more locations of a room and connected to the switch unit 1 via the connection 18.

In addition to the at least one first light source 9 of the room lighting and to the lighting means for displaying the operating state in the form of the light-emitting diodes 6 in the switch unit 1, a second light source 50 is provided in the switch unit 1. The control unit 8 can control the second light source 50 in such a way that it lights up with a low brightness in the idle mode of the switch unit 1, that is, emits only a small amount of light, which preferably corresponds to a first predeterminable or predetermined light intensity or intensity, thus only as night light serves, over which the switch unit can be found and operated by a person in the dark or about a person can orient themselves in a room at least roughly. Another application example is a use as a nightlight for

Children's room, so that the or the children in the room are not exposed to a complete darkness and thus provided by the provision of the night light quiet. When the switch presence detector unit 10 of the switch unit 1 is actuated, the at least one first light source 9 is thereby activated

turned on and the second light source 50 is turned off. The actuation of the switch-presence detector unit 10 may be carried out in the usual way, on the underside 20, the contact switch, such as the example indicated in Figure 3 dome switch 130, are arranged, which respond when pressure is applied to this and a switching operation for on and / or turn off the at least one light source of the room lighting 9 trigger. The contact or dome switch 130 may also be designed such that when they are actuated, an otherwise usual noise at switches, in particular cracking noise, is emitted becomes. The switch presence detector unit 10 can also be mounted tiltably and accordingly the contact switches are arranged so that when switching a switching operation can be triggered.

Alternatively or additionally, the sensor element 4 detects the presence of a person in the room and automatically switches on the first light source 9. For example, a switch-on is initially possible with a low brightness. If the actuation of the switch presence detector unit 10 is determined thereafter, the first light source 9 can be fully switched on, ie

Brightness be increased accordingly, thus the light output by the first light source 9. If no further actuation of the switch presence detector unit 10, if necessary, the low light output by the first light source 9 can be maintained.

Furthermore, it is possible for the first light source 9 to be switched on completely automatically after expiry of a predefinable or predefined period of time, if the sensor element 4 detects further movement or presence of at least one person in the room and also the brightness sensors 5 fall below a predefinable twilight threshold value or a brightness threshold detect. Even without operating the switch-presence detector unit 10, the first light source 9 can thus be switched on completely, a specifiable light intensity or quantity of light being emitted from the first light source 9. If no further movement in space or presence of at least one more person in the room is determined, the amount of light emitted by the first light source 9 can be reduced continuously or stepwise after a predefinable period of time for afterglow, possibly down to zero, ie until the first light source 9 is completely switched off. In turn, only the amount of light emitted by the second light source 50 can then remain in order to provide a nightlight for finding the switch unit 1 or the switch presence detector unit 0.

The second light source 50 can be made dimmable to make it shine with different brightness, for example, for the standby mode, as already mentioned above, only with a very low brightness at Detecting the presence of a person in the detection area with a higher or higher brightness to further facilitate the finding of the switch unit 1 for the person or at least to provide an orientation light for this, unless the first light source 9 is or should be turned on. The light intensity, in particular two different light intensities, the second

Light source 50 is / are application-specific (free) selectable. The first light intensity preferably leads to a less bright illumination of the second light source than the second light intensity, so that a night light can be created with the first light intensity and an orientation light with the second light intensity. Furthermore, the follow-up times for both a night and an orientation light can be selected application-specific (free).

As exemplary embodiments, a semi-automatic mode and a fully automatic mode of the switch unit 1 or control unit 8 are described in more detail below. In the semi-automatic mode, the second light source 50 is automatically switched on as a downlight with a first light intensity when the brightness value falls below a certain brightness value. Upon detection of a

Movement or the presence of a person in the space or detection range of the switch presence detector unit 10, the second light source 50 is driven to emit light having a second light intensity. After the expiration of a predefinable or predetermined delay time, the second one illuminates

Light source 50 again with the first light intensity (for example, as a night light). If the first light source 9 is switched on by the manual operation of the switch unit 1 during the follow-up time in which the second light source 50 emits light with the second light intensity, then the second light source 50 becomes complete

switched off. As soon as the first light source 9 is switched off, either by operating the switch unit 1 or automatically after the delay time has elapsed, the second light source 50 lights up again with the first light intensity (for example as night light).

In the fully automatic mode, the second light source 50 is automatically switched on at the first light level when a certain brightness value is undershot. When detecting a movement or the presence of a person in the room or

Detection range of the switch presence detector unit 0 becomes the second Light source 50 is turned off and the room lighting 9 is turned on. If no movement or presence of a person in the room or detection area of the switch presence detector unit 10 is detected more, the second light source 50 lights up again at the first light intensity after a predefinable or predefined delay time has elapsed. If the first light source 9 is switched off by manual operation of the switch unit 1, although a movement or the presence of a person in the space or detection area of the switch presence detector unit 10 is detected, the second light source 50 is switched on with the second light intensity , If thereafter no movement or presence of a person in the room or detection area of the switch presence detector unit 10 is detected, the second light source 50 automatically lights up again after the predefinable or predetermined delay time with the first light intensity.

Both in half and in the fully automatic mode, when the first light source 9 is switched on, when the switch unit 1 is actuated again, the first one

Light source 9 is turned off and the second light source 50 is turned on again as an orientation light. The latter can after expiration of a lag time or

automatically switched back to the first light intensity or completely switched off with respect to its light intensity.

Furthermore, to illuminate, for example, a narrow, long room, such as a corridor or corridor, a plurality of switch units 1 can also be connected via a bidirectional remote line. This allows a master / slave operation, wherein the settings with respect to the brightness value or the light intensity and the delay times can be made to the respective individual switch unit 1. This means that individual values can be set on each individual device or switch unit 1, which may differ from the values of the other switch unit (s) 1, or also the settings of the values at some or even all Switch units 1 can be the same. Thus, if a switch unit 1 is set to the slave mode, this switch unit 1 still has the parameters set thereon and not the parameters set on the switch unit set to the master mode. A synchronization of Switch units 1 is thus possible only manually by adapting the respective values or parameters of the individual switch units 1 to each other. The at least one first light source 9 as main or room lighting is connected to the master switch unit 1. On the remote line, the signal generated by a slave switch unit 1 due to a detected movement / presence or the signal generated by manual operation of a switch unit 1 is forwarded to the master switch unit. This in turn evaluates this signal and passes the resulting information about the switching of the second light source 50 to the slave switch unit (s) on. However, the detection of the movement or the manual operation of the switch unit 1 can also be done on the master switch unit, which then a

corresponding signal for switching the second light source 50 to the slave switch unit (s) transmitted. By the signals of the master-switch unit, the luminous intensity or luminous intensity of the second light source 50 is then controlled in accordance with the settings on the respective slave switch unit, so these depending on the direction of the master-switch unit in the mode of a night ( first light intensity) or orientation light (second light intensity), or the second light source 50 is turned off when the master switch unit turns on the first light source 9. If the first light source 9 is turned on, a corresponding signal is sent to the master switch unit by manual actuation of any switch unit 1 via the remote line, which in turn switches off the first light source 9, the second one

Light source 50 turns on at the first light level, the signal to the

Turning on the second light source 50 with the first light intensity over the

Remote line is transmitted to the slave switch unit (s). Alternatively, the first light source 9 in the absence of movement or presence signal of a person in a room or the detection range of the switch presence detector unit 10 are automatically turned off after a predetermined or predetermined delay time of the master switch unit, whereupon the master Switch unit turns on the second light source 50 at the first light intensity, and passes the signal to turn on the second light source 50 at the first light intensity via the remote line to the slave switch unit (s). FIGS. 4 to 8 show a second embodiment variant of the switch unit 1, in which a separate battery module unit 30 is provided. This is used to power the switch presence detector unit to create an emergency light, which is still functional even in the event of a power failure. As can be seen in particular from the exploded view in FIG. 5, the battery module unit 30 is provided with three rechargeable energy stores in the form of here accumulators 31, 32, 33. These are arranged on a circuit board 34, as well as other electronic components of the battery module unit 30.

Spring elements 35 are supported on the board 42 of an electronic module unit 41 or pass through it and are supported in the next level on the adjacent unit. Such spring elements can of course also be provided in a variant of the switch unit 1 without accumulators.

To protect the three energy storage or accumulator modulators 31 to 33, these are covered by a frame member 36, which can also be taken as a separate component of the exploded view in Figure 5. To protect the accumulators 31 to 33, the frame member 36 includes correspondingly shaped portions 37, 38, 39. Further, the frame member 36 is provided with front-mounted pins 40, the connection to the switch presence detector unit 10 and corresponding mounting holes on the back serve. Via the pins 40 can thus be created by simply plugging a connection to the switch presence detector unit.

As the exploded view in Figure 5 can be further removed, the electronic components of the switch unit 1 are arranged on the arrangement side of the battery module unit 30 opposite side of the frame member 36, which are also provided as a module unit 41 on the board 42. Among other things, the already mentioned control unit 8 is arranged on the board 42 of the electronic module unit 41. To the

Outside covering the battery module unit 30, the frame member 36th and the electronics module unit 41, a cover 43 is provided. This comprises four openings 44, through which cantilevered fastening elements 45 can partially reach through and latch into the rear side of the window frame 1. The with the two module units 30, 41 and the

Frame member 36 provided cover housing 43 is clipped after completion thus in a simple manner to the frame. A release of the connection can by appropriate unlatching of the cantilever

Fastening elements 45 are made from the openings 44 of the cover 43.

Since the battery module unit 30 is not permanently connected to the electronic module unit 41 or the frame 11 of the switch unit 1, but detachable, the battery module unit 30 can also be added later or be omitted entirely depending on the training if desired. FIGS. 12, 13 and 14, 15 each show the variants with inserted battery module unit 30 (FIGS. 13 and 15) and without the battery module unit (FIGS. 12 and 14) in a lateral section along line BB (FIGS 13) or line CC (FIGS. 14 and 15) according to FIG. 9. When the battery module unit 30 is provided, it is therefore not possible to use a variant in which only a conventional power supply is provided

Power supply via a rechargeable energy storage, another software to control the switch unit in terms of

Energy supply can be provided.

As energy stores 31 to 33, it is possible, for example, to provide accumulators in the form of nickel-metal hydride accumulators, which are e.g. Together, generate a voltage of 3.6 volts at 50mAh. This power is sufficient to power the switch unit 1 in the emergency light function.

For adjusting the light intensity or quantity of the light-emitting diodes

emitted light can be provided potentiometer 46 or other adjustment means, which are arranged in particular in the switch presence detector unit 10 behind the first cover member 12 (the arrangement range for the potentiometer is shown in Figure 16 and 21 by way of example by reference numeral 21 indicated) and their connections are arranged on the board 42 of the electronics module unit 41. There are several more after setting

Light intensity values, wherein the control unit 8 is used to make the respective selection of the appropriate for the desired operation or the desired mode of the switch unit light intensity value from this set amount of light intensity values.

FIGS. 9 to 23 show an alternative embodiment of the switch unit 1, in which the light-emitting diodes 6 of the switch presence detector unit and the second light source 50 are provided. The latter can be one or more

Light emitting diodes include and is in arranging the switch unit 1

For example, on a room wall W, as indicated in Figure 3, in the downwardly facing portion of the switch presence detector unit 10th

arranged. As a result, a so-called downlight is created, which emits light at a defined angle α down to the floor of the room. The second light source 50 is arranged in a separate housing 51, which has a light exit opening 52. This can be taken in particular from FIGS. 16, 21 and 23. In order to enable the light emission from the switch presence detector unit, in particular, the second

Cover member 14 also provided with a light exit opening 140. The light exit openings 52,140 are in arranging the switch unit 1 in
