Definitions

  • 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 of a mounting wall. Furthermore, the electrical installation device has a design rocker that is slidably mounted parallel to the installation direction via a wallpaper compensation area. A design frame resting on the mounting wall and surrounding the design rocker can be attached between the design rocker and the base. An electrical switching arrangement is arranged in the base, which is mechanically operatively connected to the design rocker and can be electrically connected to a lighting element. In addition, the invention relates to such an electrical installation device with a light transmission element.
  • An exemplary electrical installation device is from EP 3 059 819 A1 known.
  • the electrical installation device has a support ring as a fastening means of the base for mounting in a mounting opening.
  • a clamping piece that can be displaced in the mounting direction over a specific displacement range relative to the base is pushed onto the support ring and clamped in the support ring.
  • the clamping piece is used on the one hand to clamp the design frame between the clamping piece and support ring/wall and thus to attach the design frame to the base and on the other hand as a bearing 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, independently of the displacement position, it creates a mechanical operative connection with the base or with an inner actuating element, such as a switching rocker, formed on the base.
  • the displaceability of the clamping piece and the design rocker allows a so-called wallpaper or plaster compensation over a compensation area in the direction of assembly. This ensures, in particular, reliable functioning of the electrical installation device with switching forces that are as homogeneous as possible with different layers of wallpaper, paint or plaster applied to the support ring.
  • the displacement range corresponds to a possible wallpaper compensation range, based on the total thickness of the wallpaper, paint or plaster layers applied to the support ring.
  • an illuminated electrical installation device with a rotatable switching element from the EP 3 618 087 A1 known.
  • this electrical installation device has a lighting module with a lower shell and a lighting unit.

  • the lighting unit has a printed circuit board, a light guide element and a cover plate, the printed circuit board and the cover plate being movably mounted in the lower shell via a number of springs.
  • the cover plate, the printed circuit board and the light guide 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 can therefore not be used flexibly for other types of electrical installation devices.
  • the assembly of the lighting unit is complex, and the printed circuit board is arranged relatively unprotected in the lower shell.
  • the object of the invention is to provide an illuminated electrical installation device that enables the maximum possible luminance with the highest possible homogeneity on the light outlet element of the design rocker and at the same time ensures simple installation and the highest possible electrical safety, with a wide range of uses for different types of switches shall be.
  • the position of the lighting element can be adjusted to the shifting position of the design rocker depending on the respective installation situation and in particular depending on the thickness of the wallpaper or plaster layers applied.
  • This enables the smallest possible and, in particular, homogeneous distance between the lighting element and the light exit element of the design rocker. In addition, this enables a particularly simple assembly and in particular a simple retrofitting of a lighting element.
  • the design rocker comprises any external actuating element which is both optically detected by a user and which the user acts on to actuate the electrical installation device.
  • any push button 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 under the term design rocker.
  • the lighting element is inserted from the outside in an insertion direction into an outwardly open receiving space of the base.
  • guide surfaces laterally enclosing 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 assembly direction. This enables a compact installation space. Furthermore, the guide surfaces prevent the lighting element from tilting when it is displaced parallel to the mounting direction.
  • At least two access openings for electrical contacting of the switching arrangement with the lighting element are expediently arranged in a floor of the receiving space.
  • the reach-through openings in the floor of the receiving space avoid complex cabling and the resulting loss of performance.
  • the lighting element has a housing. It particularly preferably has a housing which is divided perpendicularly to the direction of assembly and has a housing upper part and a housing lower part.
  • the housing has in particular an inner assembly space which is preferably accessible through a two-part design of the housing.
  • the assembly room is used to arrange and protect electrical components, e.g. B. conductive metal components, a printed circuit board or a lamp.
  • the upper part of the housing and the lower part of the housing can be connected via an elastic film hinge.
  • 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 has the advantage of more accessible mounting space.
  • An electronic printed circuit board with contact areas for making electrical contact with the electrical switching arrangement of the base is preferably arranged in the lighting element, in particular in the housing.
  • the electrical contact is expediently made via contact elements that can be moved parallel to the direction of assembly.
  • at least one light source preferably an LED, is arranged on the side of the printed circuit board facing the design rocker.
  • the printed circuit board and the illuminant arranged on it enable a space-saving design that can be produced in a pre-assembly. This structure can be changed easily and quickly in the event of damage or installed in the lighting element during initial installation.
  • the printed circuit board is mounted in the mounting space of the housing and is protected by it.
  • the lighting element and the base have holding means that work together.
  • the movement of the lighting element in the direction of insertion is limited in particular by a stop surface of the base.

  • the movement of the lighting element against the direction of insertion is limited by the holding means at least up to a specific release force.
  • the holding means are preferably designed as a non-positive locking connection in the direction of insertion and counter to the direction of insertion.
  • the holding means are designed in particular in such a way that a required assembly force in the direction of insertion is smaller than the required detaching force counter to the direction of insertion.
  • the ramps designed for the non-positive locking connection can have a different slope, so that the ramp acting in the opposite direction to the direction of insertion is steeper than the ramp acting in the direction of insertion.
  • 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° around 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 reach-through openings, the lighting element can be universally adapted to the switching arrangement that is actually present by pivoting it around the circumference. As a result, the lighting element can be used more universally, which reduces production costs.
  • the function of the switching arrangement of the electrical installation device can be changed later by different cabling, with the lighting element being easily adapted to the change.
  • 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 assembly direction.
  • the guide elements prevent the contact elements from being contacted incorrectly and/or from jamming, in particular during a displacement parallel to the assembly direction. The risk of the contact elements breaking off and bending is also reduced by means of the guide elements.
  • the contact elements in one embodiment of the invention are in particular electrically connected on the one hand through the passage opening in the insertion direction in the bottom of the receiving space of the base to the electrical switching arrangement in the base and on the other hand to the electrical contact area of a printed circuit board arranged in the lighting element.
  • the accommodating space for the lighting element is ring-shaped, pointing in the opposite direction to the mounting direction Design rocker open. This enables simple assembly and simple replacement of the lighting element without removing the base from the assembly opening.

  • the light can advantageously exit the design rocker in a centered manner on the design rocker, which is of central importance for a neutral and tidy appearance.
  • the light transmission element is preferably independent of a switch position of the electrical installation device at one end in contact with a light exit element of the design rocker and at the other end in contact with the lens of the lighting element.
