Description

The invention relates to an illuminated electrical installation device such as a switch or button, having a base with fastening means for mounting along a mounting direction in a mounting opening in a mounting wall. Furthermore, the electrical installation device has a design rocker that can be moved parallel to the installation direction via a wallpaper compensation area. A design frame that rests on the mounting wall and frames the design rocker can be attached between the design rocker and the base. An electrical switching arrangement is arranged in the base, which is in mechanical operative connection with the design rocker and can be electrically connected to a lighting element. The invention also relates to such an electrical installation device with a light transmission element.

An exemplary electrical installation device is from the EP 3 059 819 A1 and from the DE102009049192 known.

The electrical installation device has a support ring as a fastening means for the base for mounting in a mounting opening. When installing the electrical installation device, a clamping piece that can be displaced relative to the base in the assembly direction over a certain displacement range is pushed onto the support ring and clamped into the support ring. The clamping piece serves, on the one hand, to clamp the design frame between the clamping piece and the support ring/wall and thus to attach the design frame to the base and, on the other hand, as a storage for the design rocker placed on the clamping piece and surrounded by the design frame. The design rocker is designed in such a way that in the displacement area, regardless of the displacement position, it establishes a mechanical operative connection with the base or with an internal actuating element formed on the base, such as a rocker switch.

The movability of the clamping piece and the design rocker enables so-called wallpaper or plaster compensation over a compensation area in the assembly direction. This ensures in particular that the electrical installation device functions reliably with switching forces that are as homogeneous as possible with different layers of wallpaper, paint or plaster applied to the support ring. In this respect, the displacement area corresponds to a possible wallpaper compensation area, based on the total thickness of the wallpaper, paint or plaster layers applied to the support ring.

In the case of such electrical installation devices, it has been shown that the luminance on a light exit element of a design rocker to display an electrical status of the switching arrangement or to display the position of the electrical installation device in darkened rooms varies depending on the installation situation, switching position and in particular depending on the layers of wallpaper or plaster applied to the support ring . As a result, in some cases the luminance is not sufficient to reliably display the electrical status of the switching arrangement or to clearly mark the position of the electrical installation device. Particularly in rooms or buildings in which several electrical installation devices have been installed, each with layers of plaster, paint or wallpaper of different thicknesses, this creates an undesirable inhomogeneous appearance when displaying the various electrical installation devices.

In addition, it has been shown that in the case of long electrical connection paths, for example if the position of the light exit element is to be arranged centrally and the electrical connection paths through the electrical installation device therefore have to be routed in a more complex manner, there is a higher safety risk due to possible spark formation from an electrical switching arrangement in the base to the lighting element or short circuits.

There is also an illuminated electrical installation device with a rotatable switching element EP 3 618 087 A1 known. For lighting, this electrical installation device has a lighting module with a lower shell and a lighting unit. The lower shell has a form-fitting locking mechanism in one The receiving space of a base housing is permanently mounted. The lighting unit has a circuit board, a light-guiding element and a cover plate, with the circuit board and the cover plate being movably mounted in the lower shell via several springs. The cover plate, the circuit board and the light-guiding element have a central access opening for the rotatable switching element. The lighting unit is specially adapted for an electrical installation device with a rotatable switching element and therefore cannot be used flexibly for other types of electrical installation devices. In addition, the assembly of the lighting unit is complex, and the circuit board is arranged relatively unprotected in the lower shell.

The invention is based on the object of providing an illuminated electrical installation device that enables the maximum possible luminance with the highest possible homogeneity on the light exit element of the design rocker and at the same time ensures simple installation and the highest possible electrical safety, allowing a wide range of usability with different types of switches shall be.

The object is achieved according to the invention by the features of claim 1. Characterized in that the lighting element is arranged displaceably mounted directly on the base parallel to the mounting direction over a region between a minimum position and a maximum position, corresponding at least to the wallpaper compensation area, and the lighting element is subjected to a displacement force by at least one spring means counter to the mounting direction in the direction of the maximum position is, the position of the lighting element can adapt to the displacement position of the design rocker depending on the respective installation situation and in particular depending on the thickness of the applied wallpaper or plaster layers. This enables the minimum and, in particular, homogeneous distance between the lighting element and the light exit element of the design rocker. In addition, this enables particularly simple installation and, in particular, simple retrofitting of a lighting element.

In the sense of the invention, the design rocker includes any external actuating element that is both visually detected by a user and on which the user acts to operate the electrical installation device. In this sense, in particular, any pushbutton with a displaceability parallel to the mounting direction and rockers, which are rotatably mounted about a pivot axis formed perpendicular to the mounting direction, are to be understood by the term design rocker.

In an advantageous embodiment of the invention, the lighting element is inserted from the outside in an insertion direction into an outwardly open receiving space of the base. In particular, guide surfaces that laterally enclose the lighting element are formed in the inner wall of the receiving space for guiding and laterally delimiting the lighting element during displacement parallel to the mounting direction. This enables a compact installation space. Furthermore, the guide surfaces prevent the lighting element from tilting when it is moved parallel to the mounting direction.

At least two access openings for electrically contacting the switching arrangement with the lighting element are expediently arranged in a floor of the receiving space. The access openings in the floor of the recording room avoid complex cabling and the resulting power losses.

Practically, the lighting element has a housing. Particularly preferably, it has a housing that is divided perpendicular to the mounting direction and has an upper housing part and a lower housing part. The housing in particular has an inner assembly space, which is preferably accessible through a two-part design of the housing. In particular, the assembly space is used to arrange and protect electrical components, e.g. B. conductive metal components, a circuit board or a lamp. Particularly advantageously, the upper housing part and the lower housing part can be connected via an elastic film hinge. Alternatively, the upper part of the housing and the Lower housing part designed to be reconnectable to one another. A film hinge advantageously reduces the risk of incorrect assembly and the loss of one of the two housing parts. A completely separate split housing, however, has the advantage of a more accessible assembly space.

Preferably, an electronic circuit board with contact areas for electrically contacting the electrical switching arrangement of the base is arranged in the lighting element, in particular in the housing. The electrical contact is expediently carried out via contact elements that are movable parallel to the mounting direction. Furthermore, at least one light source, preferably an LED, is arranged on the side of the circuit board facing the design rocker. The circuit board and the light source arranged on it enable a space-saving structure that can be produced in pre-assembly. This structure can be easily and quickly changed in the event of damage or installed in the lighting element during initial installation. The circuit board is in particular mounted in the assembly space of the housing and is protected by it.

In an advantageous embodiment, the lighting element and the base have cooperating holding means. The movement of the lighting element in the insertion direction is limited in particular by a stop surface of the base. The bottom of the receiving space preferably forms the stop surface for the lighting element in the insertion direction. However, the movement of the lighting element against the insertion direction is limited by the holding means at least up to a certain release force. For this purpose, the holding means are preferably designed as a force-fitting locking connection in the direction of insertion and against the direction of insertion. The holding means are in particular designed in such a way that a required assembly force in the insertion direction is smaller than the required release force against the insertion direction. For this purpose, in particular, the ramps designed for the force-fitting locking connection can have a different gradient, so that the ramp acting in the opposite direction to the insertion direction is designed to be steeper than the ramp acting in the insertion direction. This enables easy installation of the lighting element and a limitation of the displacement range of the lighting element in the Recording space and prevents the lighting element from falling off the base.

In order to maximize the adaptability of the electrical installation device, the lighting element and the receiving space are preferably designed in such a way that the lighting element can be used in the receiving space pivoted circumferentially by 90 ° or 180 ° about a center point of the receiving space. A further advantage is that if the lighting element is to be contacted with the switching arrangement through the access openings, the lighting element can be universally adapted to the switching arrangement actually present by pivoting around the circumference. This makes the lighting element more universally applicable, which reduces production costs. Furthermore, the function of the switching arrangement of the electrical installation device can be subsequently changed by different cabling, with the lighting element being able to be easily adapted to the change.

However, the lighting element advantageously has at least two guide elements arranged on its wall facing the base. These guide elements preferably each guide a contact element that is movably mounted parallel to the mounting direction. The guide elements prevent the contact elements from being contacted incorrectly and/or from jamming, particularly when shifted parallel to the mounting direction. The risk of the contact elements breaking off and bending is also reduced by means of the guide elements. In practice, in one embodiment of the invention, the contact elements are in electrical connection, in particular, on the one hand through the access opening in the insertion direction in the bottom of the receiving space of the base with the electrical switching arrangement in the base and, on the other hand, with the electrical contact area of a printed circuit board arranged in the lighting element.

In an advantageous embodiment, the receiving space for the lighting element is annular and faces against the mounting direction Design rocker opened. This enables easy installation and replacement of the lighting element without dismantling the base from the mounting opening.

In an advantageous embodiment, a light transmission element is designed to be displaceable over the wallpaper compensation area and forms a light guide channel, which creates a lateral offset directed perpendicular to the mounting direction for light guidance from the lens of the lighting element to a light exit element of the design rocker. The light transmission element advantageously prevents the light from being scattered. Furthermore, the light can be transmitted to the design rocker with almost no loss due to the low scattering, with a light exit point in the design rocker being able to be arranged almost anywhere on the design rocker. In this context, the light can advantageously emerge from the design rocker centered on the design rocker, which is of central importance for a neutral and tidy appearance.

In this sense, the light transmission element is preferably in contact with a light exit element of the design rocker at one end, regardless of a switch position of the electrical installation device, and in contact with the lens of the lighting element at the other end. The advantage is that the luminance is constant regardless of the switching position and/or the installation situation.

In the various figures of the drawing, the same parts are always provided with the same reference numbers.

The following description claims that the invention is not limited to the exemplary embodiments and not to all or several features of the combinations of features described, but rather each individual partial feature of the/each exemplary embodiment is also detached from all other partial features described in connection therewith also in combination with any features of another exemplary embodiment of importance for the subject matter of the invention.

The Figures 1 , 2 and 11 each show a first, second and third embodiment of an electrical installation device 1a, 1b, 1c, 1d according to the invention. According to the illustrations, the electrical installation device 1a, 1b, 1c, 1d can be designed, for example, in the form of a switch or button.

The electrical installation device 1a, 1b, 1c, 1d has a base 2a, 2b, 2c with fastening means for mounting along a mounting direction M in a mounting opening. The assembly opening has not been shown. The mounting opening is preferably formed in a wall or a control box. In particular, the mounting opening is formed in a wall of a room or a house wall. The mounting opening can expediently be formed by a flush-mounted installation box or a surface-mounted housing arranged in or on a wall. For assembly, the electrical installation device 1a, 1b, 1c, 1d is inserted into the assembly opening in an assembly direction M. In this sense, the fastening means are preferably designed as a circumferential support ring 3 connected to the base 2a, 2b, 2c and/or as claws 5 arranged opposite one another on the circumference of the base 2a, 2b, 2c for fastening in the mounting opening.

Furthermore, the electrical installation device 1a, 1b, 1c, 1d corresponds to the illustrations in the Figures 1 , 2 and 11 at least one design rocker 4. As can be seen in particular from the Figures 10b and 10c or the Figures 16 to 19 results, the design rocker 4 is parallel to the mounting direction M over a Wallpaper leveling area T (see in particular the Figures 10b, 10c , 18 and 19 ) stored movably.

For the purposes of the invention, the design rocker 4 includes any external actuating element that is optically detected by a user and/or on which a user acts to operate the electrical installation device 1a, 1b, 1c, 1d. In this sense, in particular, any pushbutton with a displaceability parallel to the mounting direction M is also included under the term design rocker 4. Furthermore, a design rocker 4 also relates to rockers which are rotatably mounted about a pivot axis directed perpendicular to the mounting direction M. Exemplary versions of the electrical installation device 1a, 1b, 1c, 1d are in the Figures 1 , 2 and 11 shown, with the design of the electrical installation device 1c in Figure 2 advantageously has two independently operable design rockers 4.

The design rocker 4 is in an operative connection with an electrical switching arrangement arranged in the base 2a, 2b, 2can.

The base 2a, 2b, 2c in particular has at least two connection contacts 6, preferably designed as sleeves, for connecting electrical conductors, not shown. In the base 2a, 2b, 2c there are also several electrical contact parts, not shown, which are at least partially designed to be mechanically movable between a first and a second position, in particular in the form of at least one electrically conductive contact rocker, and which electrically connect the connection contacts 6 differently depending on the position. In this respect, the contact parts and connection contacts 6 together form an electrical circuit which, depending on the design of the electrical installation device 1a, 1b, 1c, 1d or depending on the selection of the connection contact 6 for a specific cable, can have different switching functions related to the connection contacts 6. Common exemplary electrical circuits are a simple on/off circuit, a changeover circuit or a cross circuit.

In addition, the electrical installation device 1a, 1b, 1c, 1d has at least one switching element 8 for mechanical actuation of the contact rocker. In particular, the switching element 8 is a rocker switch, as in the exemplary embodiments in the Figures 1 , 2 and 11 shown. The switching rocker is preferably mounted on the base 2a, 2b, 2c so that it can be tilted or pivoted between at least a first and a second position corresponding to the contact rocker and is in particular in a mechanical operative connection with the contact rocker in order to move it into at least the first or second position. Alternatively, the design rocker 4 for an electrical installation device 1a, 1b, 1c, 1d designed as a push button is mounted displaceably between at least a first position and a second position parallel to the mounting direction M.

The design rocker 4 can be plugged onto the electrical installation device 1a, 1b, 1c, 1d as a separate part, preferably detachably, so that when plugged in it is in operative connection with the switching element 8, in particular the switching rocker, and can be removed without being destroyed. For a switching process, the user of the electrical installation device 1a, 1b, 1c, 1d operates the design rocker 4, which in turn moves the switching element 8 or the switching rocker into at least the first or second position according to the circuit, and which in turn moves the contact rocker into its corresponding positions is moved and the electrical circuit switches accordingly.

Preferably, the base 2a, 2b, 2c, according to the embodiments in the Figures 1 , 2 and 11 , at least one bearing means 10a, 10b, 10c for storing and releasably fastening the design rocker 4. The bearing means 10a, 10b, 10c is preferably designed such that the design rocker 4 can be displaced relative to the base 2a, 2b, 2c parallel to the mounting direction M at different distances between a maximum distance and a minimum distance from the base 2a, 2b, 2c Base 2a, 2b, 2c can be attached. In particular, the bearing means 10a, 10b, 10c is designed as a clamping piece that can be clamped or releasably locked in a force-fitting manner on or into the base 2a, 2b, 2c in several positions arranged one behind the other in the assembly direction M. The bearing means 10a, 10b, 10c in particular has a direction perpendicular to the mounting direction M running bearing point 12a, 12b, 12c. In particular, the design rocker 4 can be clipped onto the bearing point 12a, 12b, 12c in a force-fitting, detachable, latching manner.

The mechanical active connection between the design rocker 4 and the switching element 8, or the switching rocker, is advantageously designed in such a way that the active connection is independent of a displacement of the design rocker 4 parallel to the mounting direction M in a distance range between the maximum distance and a minimum distance between the design rocker 4 and the base 2a, 2b, 2c is made possible. For this purpose, at least one dome of the design rocker 4, not shown, extending in the direction of the switching element 8, preferably engages in at least one receiving chamber 14a, 14b of the switching element 8 extending in the direction of the design rocker 4.

Due to the displaceability of the design rocker 4 via the bearing means 10a, 10b, 10c, so-called wallpaper compensation can be made possible. This allows an improved adjustment of the positioning of the design rocker 4 with additional layers of wallpaper or paint applied to the support ring 3 after the base 2a, 2b has been installed. This minimizes negative effects of the additional layers on the switching feel and/or the distance dimensions between the design rocker 4 and a design frame 16. The one in the Figures 1 , 2 , 7, 8 , 9 , 10c , 11 to 13 , 16 , 18 and 19 The design frame 16 shown, which is usually mounted on the base 2a, 2b, 2c to cover the electrical installation device 1a, 1b, 1c, 1d, would then have a different relative position to the design rocker 4 depending on the number of layers of wallpaper or paint applied. The displaceability along the mounting direction M creates a particularly homogeneous appearance that is adapted to the design of the design rocker 4 and the design frame 16, without negatively influencing the switching feel or switching function of the electrical installation device 1.

The embodiment according to Figures 1 and 11 has exactly one switching element 8 and one design rocker 4. The embodiment according to Figure 2 has two switching elements 8 designed as rocker switches and two design rockers 4. In particular, there are preferably two separate ones in the base 2c electrical circuits are arranged, each with a contact rocker, which are switched separately by the respective pair of design rocker 4 and switching element 8, or switching rocker.

The electrical installation device 1a, 1b, 1c, 1d also has a lighting element 18a, 18b, 18c, 18d, which in various embodiments is exemplary in the Figures 3 , 4 , 5 , 6 , 14 and 15 is shown. The embodiments of the lighting element 18a according to Figure 3 , of the lighting element 18b according to Figure 4 and the lighting element 18c according to Figure 5 are externally designed to be the same in terms of the housing, but can display different lighting functions, which will be discussed in more detail below.

The lighting element 18a, 18b, 18c, 18d is preferably designed as a completely closed housing part and is in particular electrically connected to the switching arrangement in the base 2a, 2b, 2c. The lighting element 18a, 18b, 18c, 18d is thereby advantageously supplied with an electrical voltage, and it can display the position of the electrical installation device 1a, 1b, 1c, 1d, or the design rocker 4, for a user. In an advantageous embodiment, the lighting element 18a, 18b, 18b, 18d is supplied with an electrical voltage which is dependent on a switch position of the electrical switching arrangement. In particular, the user can thereby visually recognize the switching state of the switching arrangement using the lighting element 18a, 18b, 18c, 18d.

In this regard, the lighting element 18a, 18b, 18c, 18d expediently has at least one light source 20. The embodiments of the lighting element 18a, 18b, 18d correspond to the example in the Figures 1 , 3 , 4 and 11 have exactly one light source 20. The embodiment of the lighting element 18c according to Figure 2 , 5 and 7 has two lamps 20. The lighting element 18c is preferably designed and switched in such a way that it has two lighting means 20 that can be controlled electrically independently of one another. The lamp 20 is advantageously on one side of the lighting element 18a, 18b, 18c, 18d facing opposite to the mounting direction M.

In principle, an electrical installation device 1a, 1b, 1c, 1d with three independent electrical circuits is also possible, in which case the electrical installation device 1a, 1b, 1c, 1d has three switching elements 8, three design rockers 4 and preferably also three independently electrically controllable lamps 20 .

Preferably, according to the statements in the Figures 3 to 6 and 15 , at least one LED is designed as a light source 20 on the lighting element 18a, 18b, 18c, 18d. In particular, there is also a light exit opening 22 in the design rocker 4, as in the Figures 1 , 2 and 11 shown, arranged, from which the light generated by the lighting element 18a, 18b, 18c, 18d emerges. It is particularly advantageous if a light exit element 24 is arranged in the light exit opening 22 for bundling or scattering or coloring the light. In this sense, it is particularly advantageous for a lighting element 18c according to Figures 2 , 5 and 7 with more than one light source 20, the electrical installation device 1c has a light exit element 24 and/or a light exit opening 22 formed for each light source 20.

According to the invention, the lighting element 18a, 18b, 18c, 18d is arranged to be displaceable directly on the base 2a, 2b, 2c parallel to the mounting direction M over a range between a minimum position and a maximum position. The area corresponds at least to the wallpaper compensation area T. By means of at least one spring means 26a, 26b, in particular a helical spring, the lighting element 18a, 18b, 18c, 18d is subjected to a displacement force in the direction of the maximum position against the assembly direction M of the electrical installation device. Examples include various versions of the spring means 26a, 26b or the arrangement and number of spring means in the Figures 3 to 5 and 15 shown.

The lighting element 18a, 18b, 18c, 18d is expediently inserted from the outside in an insertion direction E into an outwardly open receiving space 28a, 28b of the base 2a, 2b. The respective receiving spaces 28a, 28b are advantageous in the Figures 1 , 2 and 16 shown. In particular, guide surfaces 32a, 32b are formed in an inner wall 30a, 30b of the receiving space 28a, 28b. The guide surfaces 32a, 32b enclose the lighting element 18a, 18b, 18c, 18d laterally and preferably serve to guide and laterally limit the lighting element 18a, 18b, 18c, 18d during displacement parallel to the mounting direction M. Advantageously, this design enables simple subsequent mounting the lighting element 18a, 18b, 18c, 18d or a simple replacement of the same.

In particular, in a bottom 34a, 34b of the receiving space 28a, 28b, as in the Figures 1 , 2 , 10 and 16 to 19 shown, at least two through openings 36a, 36b are arranged for electrically contacting the switching arrangement with the lighting element 18a, 18b, 18c, 18d. Through the access openings 36a, 36b in the bottom 34 of the receiving space 28, complex cabling is avoided. In particular, this enables a compact installation space and reduces the manufacturing effort.

In the Figures 3 to 5 and 14 and 15, four different embodiments of a lighting element 18a, 18b, 18c, 18d are shown. The lighting element 18a, 18b, 18c, 18d in particular has a housing 38a, 38b. The housing 38a, 38b is preferably a housing 38a, 38b divided into two perpendicular to the mounting direction M with an upper housing part 40a, 40b and a lower housing part 42a, 42b. The housing 38a, 38b in particular has an inner assembly space 44a, 44b, which is accessible through a two-part design of the housing 38a, 38b. The assembly space 44a, 44b expediently serves to arrange and protect electrical components, e.g. B. a circuit board 46a, 46b, 46c, at least two spring means 26a, 16b or partially the contact elements 58a, 58b. According to an advantageous embodiment, the upper housing part 40a, 40b and the lower housing part 42a, 42b are in particular above Locking means 48 can be connected to one another. In the Figures 3 to 5 only the locking means 48 of a pair of locking means are marked.

Particularly advantageously, the upper housing part 40b and the lower housing part 42b can be connected via an elastic film hinge 50, according to the exemplary embodiment Figure 15 , be connected. Alternatively, the upper housing part 40a and the lower housing part 42a, according to the exemplary embodiments of Figures 3 to 5 , designed to be completely detachable and reconnectable. A film hinge 50 advantageously reduces the risk of incorrect assembly and the loss of one of the two housing parts. A completely separate two-part housing 38a, however, has the advantage of a more accessible assembly space 44a.

According to one embodiment of the invention, according to the statements of Figures 3 to 5 , at least one lens 54 for light transmission is integrated in a cover wall 52 of the lighting element 18a, 18b, 18c facing the design rocker 4. Useful for lighting elements 18c with more than one lamp 20, as in Figure 5 and 6 shown, the lighting element 18c has a lens 54 for each lamp 20.

It is advantageous in the lighting element 18a, 18b, 18c, 18d, in particular as in the Figures 3 to 5 and 15 indicated in the housing 38a, 38b, at least one electronic circuit board 46a, 46b, 46c, 46d with contact areas 56 for electrically contacting the electrical switching arrangement of the base 2a, 2b, 2c is arranged. The light source 20 is advantageously formed on a side of the circuit board 46a, 46b, 46c that faces opposite to the mounting direction M. By way of example, more than one circuit board can also be arranged in the housing 38a, 38b of the lighting element 18a, 18b, 18c, 18d, depending on the design of the circuit board 46a, 46b, 46c, 46d. This can be done, for example, in one of the Figures 1 to 5 shown housing 38a of the lighting element 18a two circuit boards 46b according to the embodiment Figure 4 to record.

The contact areas 56 are particularly advantageous with the electrical contact elements 58a, 58b which are movable parallel to the mounting direction M Switching arrangement of the base 2a, 2b contacted. The Figures 10 and 15 to 19 show exemplary embodiments in which the contact elements 58a, 58b protrude through the access openings 36a, 36b into an area of the connection contacts 6 and use them to contact the electrical switching arrangement of the base 2a, 2b.

The contact elements 58a, 58b are in particular in the Figures 3 to 5 , 14 and 15 shown. Preferably, at least one light source 20, in particular an LED, is arranged on the side of the circuit board 46a, 46b, 46c, 46d facing the design rocker 4.

In order to avoid jamming and tilting when moving the lighting element 18a, 18b, 18c, 18d parallel to the mounting direction M, there is preferably between a peripheral wall 64a, 64b of the lighting element 18a, 18b, 18c, 18d and the inner wall 30a, 30b of the receiving space 28a, 28b there is a storage gap. Furthermore, depending on the shape of the bearing gap, the lighting element 18a, 18b, 18c, 18d can pivot slightly towards the assembly direction, whereby in particular further assembly tolerances with respect to the bearing means 10a, 10b, 10c or the base 2a, 2b, 2c can be compensated for.

In one embodiment of the invention, the lighting element 18a, 18b, 18c, 18d, as shown in FIGS Figures 1 to 6 , 11 , 14 and 15 shown, and the base 2a, 2b, 2c has holding means that interact in a force-fitting and/or form-fitting manner, in particular in the form of a holding cam 60a, 60b. The movement of the lighting element 18a, 18b, 18c, 18d is preferably limited in the insertion direction E by a stop surface of the base 2a, 2b and limited against the insertion direction E by the holding means, in particular the holding cams 60a, 60b, at least up to a certain release force . In particular, the bottom 34a, 34b of the receiving space 28a, 28b is the stop surface of the base 2a, 2b for the lighting element 18a, 18b, 18c, 18d in the insertion direction E.

In an advantageous embodiment, the lighting element 18a, 18b, 18c, 18d and the receiving space 28a, 28b are designed such that the lighting element 18a, 18b, 18c, 18d can be inserted into the receiving space 28a, 28b circumferentially pivoted by 90 ° or 180 ° about a center of the receiving space 28a, 28b. Accordingly, the lighting element 18a, 18b, 18c, 18d according to the statements in the Figures 3 to 5 by 180 ° and according to the Figures 14 and 15 pivoted by 90 ° around the center of the respective receiving space 28a, 28b, can be used. An advantage here is that if the lighting element 18a, 18b, 18c, 18d is to be contacted with the switching arrangement through the access openings 36a, 36b, the lighting element 18a, 18b, 18c, 18d can be universally adapted to the actually present switching arrangement by rotation can. This makes the lighting element 18a, 18b, 18c, 18d more universally usable. Furthermore, the switching arrangement of the electrical installation device 1a, 1b, 1c, 1d can be changed subsequently, with the lighting element 18a, 18b, 18c, 18d being able to be easily adapted to the change.

However, the lighting element 18a, 18b, 18c, 18d, as in the Figures 3 to 5 , 14 and 15 shown, at least two, on its wall facing the base 2a, 2b, 2c, in particular a bottom wall according to the embodiment of the lighting element 18a, 18b, 18c in the Figures 3 to 5 , or preferably the cover wall 52 according to the design of the lighting element 18d in the Figures 14 and 15 , arranged guide elements 62a, 62b. At least two of the guide elements 62a, 62b preferably each guide a contact element 58a, 58b that is movably mounted in the mounting direction M. The guide elements 62a, 62b prevent the contact elements 58a, 58b from being contacted incorrectly and/or from jamming, in particular when displaced parallel to the mounting direction M.

The contact elements 58a, 58b expediently stand on the one hand through the access opening 36a, 36b in the insertion direction E in the bottom 34a, 34b of the receiving space 28a, 28b of the base 2a, 2b, 2c with the electrical switching arrangement, in particular the connection contact 6, in the base 2a, 2b , 2c and on the other hand with the electrical contact area 56 of a circuit board 46a, 46b, 46c arranged in the lighting element 18a, 18b, 18c, 18d, 46d, as exemplified in the Figures 10 and 16 to 19 shown, in electrical connection.

In particular in the embodiments of the electrical installation device 1a, 1b, 1c, which in the Figures 1 to 10 are shown, the lighting element 18a, 18b, 18c has the cooperating holding means on its peripheral wall 64a and the receiving space 28a of the base 2a on its inner wall 30a. The holding means are preferably designed as force-fitting locking means. The holding means enable the lighting element 18a, 18b, 18c to be releasably snapped into the receiving space 28a of the base 2a in the insertion direction E and prevent removal against the insertion direction E up to a certain release force.

In an advantageous embodiment, which in the Figures 3 to 5 is shown, the holding means of the lighting element 18a, 18b, 18c are designed as holding lugs 60a on the peripheral wall 64a.

The holding nose 60a advantageously extends parallel to the mounting direction M and protrudes perpendicularly from the peripheral wall 64 at a nose height. In particular, the holding nose 60a has an insertion ramp 66, which extends like a ramp from the nose height in the insertion direction E to a level of the peripheral wall 64a. Furthermore, the holding nose 60a preferably has a resistance ramp 68, which extends like a ramp from the nose height against the insertion direction E to a level of the peripheral wall 64a. Particularly advantageously, the resistance ramp 68 is designed to be steeper than the insertion ramp 66 so that the release force for removing the lighting element 18a, 18b, 18c is greater than an assembly force which is necessary to move the lighting element 18a, 18b, 18c in the insertion direction E in the receiving space 28a to assemble. In the exemplary embodiments of Figures 3 to 5 the lighting element 18a, 18b, 18c advantageously has four retaining lugs 60a.

In particular, the holding means of the receiving space 28a of the base 2a are designed as recesses 61a running in the insertion direction E. Preferably grab the respective retaining lugs 60a into the recesses 61a, preferably a retaining groove or a slot-like opening, formed oppositely on the inner wall 30a of the receiving space 28a of the base 2a, the retaining lugs 60a advantageously being moved when the lighting element 18a, 18b, 18c moves along the insertion direction E can be guided laterally in the recesses 61a.

In one embodiment of the invention, the receiving space 28a is as shown in FIGS Figures 1 and 2 shown, opened in a ring shape pointing against the assembly direction towards the design rocker 4. Particularly advantageous is the lighting element 18a, 18b, 18c corresponding to the annular receiving space 28a, as in the Figures 3 to 5 shown, also ring-shaped. Particularly advantageously, a storage gap is present both between the inner and an outer peripheral wall 64a of the lighting element 18a, 18b, 18c and between an inner and outer inner wall 30a of the receiving space 28a, whereby the lighting element 18a, 18b, 18c moves particularly slightly around the mounting direction M can tilt.

Like in the Figures 1 and 2 shown, the receiving space 28a is preferably formed in a ring shape around the switching element 8 or around the switching rocker.

The lighting element 18a, 18b, 18c can expediently also be U-shaped, C-shaped or L-shaped in an embodiment not shown and inserted into the annular receiving space 28a.

Preferably, the guide elements 62a are in the versions shown in the Figures 3 to 5 are shown, designed as guide sleeves. The guide sleeves advantageously each form an opening in the lighting element 18a, 18b, 18c, with the contact elements 58a, which are movably mounted parallel to the mounting direction M, being arranged in at least two of the guide sleeves. The guide sleeves have the practical advantage that they guide the contact elements 58a. The guide sleeves can be designed to correspond to the contact elements 58a in such a way that the Contact elements 58a do not tilt or tilt from a predetermined position, in particular perpendicular to the lighting element 18a, 18b, 18c.

In a further embodiment, the guide sleeves and the contact elements 58a can be designed to correspond to one another in such a way that penetration of dirt or dust into the housing 38a of the lighting element 18a, 18b, 18c is reduced or prevented. In this sense, the guide sleeves can also have a sealing effect against moisture, in particular by means of sealing elements.

Preferably, the contact elements 58a in a variant of the invention, as in Figure 10 shown, each has an electrically conductive spring means 26a, in particular an electrically conductive coil spring, with electrically conductive contact pins fastened on one side in the coil spring, guided in the guide sleeve and electrically conductive. This can be advantageous as shown in Figure 10 the electrical contact to the circuit board 46a can be made by means of the coil spring. The side of the contact element 58a facing away from the circuit board 46a preferably projects into the access openings 36a in the bottom 34a of the base 2a for electrical contacting of the switching arrangement.

The arrangement by means of a spring means 26a, in particular the coil springs, further enables a spring-loaded mounting of the lighting element 18a, 18b, 18c, whereby a movement of the lighting element 18a, 18b, 18c parallel to the mounting direction M and also preferably a pivoting of the lighting element 18a, 18b, 18c can be made possible around the mounting direction M. In particular, a spring means 26a is provided with at least one coil spring, which applies a displacement force to the lighting means 18a, 18b, 18c counter to the mounting direction M in the direction of the maximum position.

Particularly preferred is the lighting element 18a, 18b, 18c in the receiving space 28a of the base 2a, 2b, 2c by means of the spring means 26a and the holding means, in particular the holding lugs 60a and the recesses 61a floating on the base 2a, 2b, 2c between the minimum position and the maximum position.

According to a further alternative of the electrical installation device 1d, the guide elements 62b, as in the Figures 11 and 14 to 19 shown, designed as clamping arms extending in the insertion direction E. The guide elements 62b protrude, as in the Figures 16 to 19 shown, through a breakthrough 72 from the lighting element 18d. The contact elements 58b, which are movably mounted parallel to the mounting direction M, are advantageously arranged on at least two of the guide elements 62b. The contact elements 58b are expediently arranged as contact tongues on a guide side 74 of the guide elements 62b in such a way that they are preferably mounted so that they can be displaced relative to the guide elements 62b parallel to the assembly direction M, at least over the wallpaper compensation area T.

In particular, the contact elements 58b are clamped by means of the guide elements 62b perpendicular to the mounting direction M against a wall of the access opening 36b and/or a clamping surface of the switching arrangement or the connection contact 6. By means of the material design of the contact elements 58b, the guide elements 62b, the base 2c in the area of the access opening 36b and / or the clamping surface of the switching arrangement or the connection contact 6, the friction between the guide element 62b and the access opening 36b, between the guide element 62b and the contact element 58b and between Contact element 58b and access opening 36b and/or the clamping surface of the switching arrangement can be adjusted in such a way that when the lighting element 18d is displaced parallel to the mounting direction M, the contact elements 58b are fixed relative to the base 2c, whereas the lighting element 18d shifts parallel to the mounting direction M . In particular is in Figure 17 , 18 a state is shown in which the lighting element 18b is in the maximum position, and in Figure 16 , 19 a state is shown in which the lighting element 18d is in the minimum position. Both in the minimum position and in the maximum position of the lighting element 18d The relative position of the contact elements 58b to the base 2c remained constant.

The contact elements 58b preferably act simultaneously, in particular together with the guide elements 62b, as holding means. In this regard, the contact elements 58b are expediently arranged in the access opening 36b in the bottom 34b of the receiving space 28b of the base 2c in such a way that they are clamped between the respective guide element 62b and the electrical switching arrangement in the base 2c so that the removal of the lighting element 18d against the insertion direction E up to a certain release force is prevented. Advantageously, the contact elements 58b and/or the guide elements 62b and/or the base 2c itself can alternatively or additionally be blocking means, not shown, e.g. B. have a latching element, which preferably protrude perpendicular to the mounting direction M from the respective guide element 62b or contact element 58b and / or base 2c. Corresponding to the protruding blocking means, the guide element 62b or the contact element 58b and/or the base 2c can also have a receptacle for a blocking means.

In an advantageous embodiment, the contact elements 58b are each connected on one side to the electrically conductive spring means 26b, in particular an electrically conductive coil spring, to the circuit board 46b arranged in the lighting element 18d. As a result, the spring means 26b, preferably the coil springs, advantageously establish an electrical connection between the switching arrangement and the circuit board 46b. The circuit board 46b itself is advantageously mounted immovably in the lighting element 18d. By arranging and clamping the contact elements 58b in the through openings 36b and by means of the coil springs, which are arranged on a printed circuit board 46b immovably connected to the lighting element 18d, the lighting element 18d is mounted in a floating manner.

In particular, in the execution in the Figures 14 and 15 the spring means 26b, or the coil spring, a tension spring and the receiving space 28b in Open facing assembly direction M. In an unloaded state, ie when the electrical installation device 1d, as in Figure 17 shown, is not mounted in an installation opening or the electrical installation device 1d, as in Figure 18 shown, a maximum wallpaper compensation area T is bridged, the lighting element 18d is in the maximum position and maximally drawn into the receiving space 28. When moving to the minimum position, ie with an electrical installation device 1d mounted in an installation opening with a minimal or no wallpaper compensation area T, the lighting element 18d is as in the Figures 16 and 19 shown, shifted maximally out of the receiving space 28b against the insertion direction E, the coil springs are stretched and always exert the displacement force in the insertion direction E and against the assembly direction M. To illustrate this, the distance B from the lighting element 18d to the floor 34b or the stop surface of the receiving space 28b is in the Figures 16 and 19 , which represent the minimum position of the electrical installation device 1d.

The receiving space 28b is expediently formed on the side of the base 2c facing away from the design rocker 4 and is opened in the assembly direction M. This makes the installation space advantageous, for example. B. a complex switching gate, enlarged on the side of the base 2c facing the design rocker 4. In this sense, a lens 54 of the lighting element 18d could be arranged on a particularly cylindrical light guide 76. The light guide 76 expediently extends, as in the Figures 14 to 16 shown, in insertion direction E and accordingly Figure 16 through a light guide opening in the base 2c. The light guide 76 has the practical advantage that it guides the light generated by the lamp 20, or the LED, through the base 2c to the lens 54.

In Figure 15 a practical structure with a light guide 76 is shown. In particular, by means of the light guide 76, a synergistic effect of the largest possible receiving space 28b on the side of the base 2c facing away from the design rocker 4 and a particularly large installation space, e.g. B. for a complex switching gate, on the side facing the design rocker 4 Base 2c is created, at the same time the light is optimized in preferably a light guide 80c in the storage means 10c and in particular from there into a particularly preferred area near the design rocker 4.

Preferably there is a protective tube 78 on the housing 38b, as shown in FIGS Figures 14 and 15 shown, arranged or formed, through which the light guide 76 passes. In particular, the protective tube 78 bridges a distance between the housing 38b and the bearing means 10c. Furthermore, the protective tube 78 reduces tilting about the mounting direction M of the lighting element 18d relative to the base 2c and of the light guide 76 relative to the housing 38b. Another aspect is that the axial overlap between the light guide 76 and the protective tube 78 prevents or makes more difficult the penetration of dirt and moisture, if necessary with the addition of a sealing element.

In a further variant, the lighting element 18d enables the Figures 11 , and 13 to 18 that the light guide 76 together with the lens 54 is arranged directly under the light entry area of the light guide 80c in the bearing means 10c and, on the one hand, is arranged close to the area of the design rocker 4 and, on the other hand, particularly centrally to the base 2b, in particular leading through the switching element 8, as in Figure 11 shown, is arranged.

In a possible embodiment, a light transmission element 80a, 80b, 80c is arranged adjacent to a lens 54 of the lighting element 18a, 18b, 18c. The light transmission element 80a, 80b, 80c is in the Figures 1 , 2 , 9 , 11 and 16 shown. Figure 2 shows an advantageous electrical installation device 1c, which has two light transmission elements 80b, whereby the number of light transmission elements 80b present can be adapted to the number of light exit openings 22 in the design rockers 4 or other user wishes.

The light transmission element 80a, 80b, 80c is designed in such a way that it is slidably mounted over the wallpaper compensation area T of the electrical installation device 1a, 1b, 1c, 1d and forms a light guide channel which has a lateral offset directed perpendicular to the mounting direction for light guidance from the lens 54 of the lighting element 18a, 18b, 18c, 18d to a light exit element 24 of the design rocker 4. In particular, the light transmission element 80a, 80b, 80c can transmit a light emerging from the lens 54 perpendicularly and parallel to the mounting direction M up to the design rocker 4. Particularly advantageously, the light transmission element 80a, 80b, 80c guides the light optically from the lens 54 on the lighting element 18a, 18b, 18c, 18d to a light exit opening 22 or to the light exit element 24 of the design rocker 4. The light transmission element is 80a, 80b, 80c designed in such a way that the light can emerge from a light exit element 24 at any laterally offset position or in particular positioned centrally in the design rocker 4.

The light transmission element 80a, 80b, 80c thereby makes it possible to position the light exit opening 22 or the light exit element 24 on the design rocker 4 in an attractive manner for the user. Furthermore, the surfaces of the light transmission element 80a, 80b, 80c reduce scattering of the light. A transparent light transmission element 80a, 80b, 80c, particularly made of plastic, has proven to be useful for the purposes mentioned.

Preferably, the light transmission element 80a, 80b, 80c is designed such that the light transmission element 80a, 80b, 80c is in contact at one end with an at least partially transparent light exit element 24 of the design rocker 4 and / or the, regardless of a switch position of the electrical installation device 1a, 1b, 1c, 1d Light exit opening 22 and at the other end is in contact with the lens 54 of the lighting element 18a, 18b, 18c, 18d.

The light transmission element 80a, 80b, 80c can be optimally adapted to the design of the lighting element 18a, 18b, 18c, 18d or the electrical installation device 1a, 1b, 1c, 1d. By way of example, the light transmission element 80a can be as shown in FIGS Figures 1 and 9 shown, or the light transmission element 80c, as in Figure 11 shown, the light from a single lens 54 arranged on an annular lighting element 18a, 18b, 18d into a central position of the design rocker 4, as in Figure 7 shown, visually guide. The Electrical installation device 1c according to Figure 2 however, has two lenses 54, which are arranged 180 ° opposite each other on a likewise ring-shaped lighting element 18c. Here, two separate light transmission elements 80b can advantageously be used, as in Figure 2 shown, or a coherent light transmission element 80a, as in the Figures 1 and 9 shown, can be used, whereby two separate light transmission elements 80b can, for example, also display two separate electrical circuits and thereby preferably four different switching positions, whereas a coherent light transmission element 80a can bundle and guide the light from two lenses 54.

The light transmission element 80c in the electrical installation device 1d according to the embodiment in Figure 11 Meanwhile, the light is directed from a central light guide 76, in particular arranged in a switching element 8, together with a lens 54, to a light exit opening 22 or light exit element 24, which is offset radially from the mounting axis and from the central position, as in the Figures 12 and 13 shown. This version can be used by the user to determine the alignment, e.g. B. above and / or below, the design rocker 4 may be useful in order to recognize the function of the respective switching position.

In the Figures 20 to 23 Four advantageous types of circuits are symbolically represented, which can be implemented by an electrical installation device 1a, 1b, 1c, 1d. The electrical installation device 1a, 1b, 1c, 1d is each connected to a phase L, as a current-carrying conductor, and a neutral conductor N, as a current-returning conductor.

Figure 20 shows an advantageous embodiment as an on/off circuit, according to which the lighting element 18a, 18d according to Fig. 3 or 14 is designed such that the user has a visual control option for an active consumer 84. The lighting element 18a, 18d is connected to the base 2a, 2c, in particular by means of the contact elements 58a, 58b, so that when the consumer 84 is switched on, the lighting element 18a, 18d lights up and the user can visually recognize the active consumer 84. This is often used for bathroom light switches, for example.

Figure 21 shows one too Figure 1 Similar advantageous embodiment as an on/off switch, according to which the lighting element 18a, 18d is designed such that the user has a visual orientation aid, e.g. B. for installation in dark places or in stairwells. The lighting element 18a, 18d is connected in such a way that the lighting element 18a, 18d lights up regardless of the switching state of the electrical installation device 1a, 1d.

Figure 22 shows an advantageous embodiment as a changeover switch according to which the lighting element 18b, 18d is designed such that the user has an optical lighting aid for an active consumer 84. The lighting element 18b, 18d is connected to the base 2a, 2c via the contact elements 58a, 58b in such a way that it always lights up in the opposite direction to the switched state of the consumer 84. In the circuit, depending on the switching state, the consumer 84 or the lighting element 18b, 18d is connected to the current-carrying phase L.

Figure 22 shows an advantageous embodiment as a series circuit, according to which the lighting element 18c according to Fig. 2 and Fig. 5 is designed in such a way that the user has a visual control option for two independently switched consumers 84. The lighting element 18c is connected to the base 2b, in particular by means of the contact elements 58a, so that when the respective consumers 84 are switched, the lighting means 20 of the lighting element 18c assigned to the consumer 84 lights up and the user can visually recognize the active consumer 84.
