Definitions

  • the invention relates to an electrical switch that can be operated with a key card.
  • This has a button insert that includes electrical connection contacts, electrical switching elements and a rocker switch.
  • the rocker switch is used to operate the electrical switching elements.
  • the button insert can be mounted in a mounting opening using a support ring.
  • the support ring can be stored in a mounting plane on an edge area of the mounting opening.
  • a cover frame can also be placed on the support ring.
  • the electrical switch also has a rocker support and a cover arrangement.
  • the rocker support is connected to the rocker switch.
  • the cover arrangement has an insertion channel for a key card to be inserted.
  • the rocker support protrudes into the insertion channel in such a way that when the key card to be inserted is inserted in an insertion direction parallel to the mounting plane, the key card can contact the rocker support in such a way that the rocker support carries out a mechanical switching movement. The mechanical switching movement is thereby transferred to the rocker switch.
  • the insertion channel is designed such that when the key card is correctly inserted, the key card can be arranged in an insertion plane that extends parallel to the mounting plane within the insertion channel.
  • the key cards and the electrical switch often also have a security device that serves as proof of authorization for the function to be activated.
  • security devices are based on radio frequency identification (RFID) technology, in particular a near field communication (NFC) standard.
  • RFID radio frequency identification
  • NFC near field communication
  • An authorization feature e.g. a code, is usually stored on the key card, which is queried or read by a reading device in the electrical switch.
  • a switching element within the electrical switch is moved to a first switching position.
  • This switching position can in particular bring about a permanent electrical contact for the time in which the key card is inserted into the electrical switch, or only a temporary contact.
  • electrical switches are known to be installed at different times during the construction phases of a building, for example directly during house construction or following renovation, electrical switches are regularly installed on different surfaces, in particular wallpaper, bare walls, painted walls or plastered walls.
  • a cover frame which serves to visually enhance and protect the electrical switch and surrounds the electrical switch, often rests on the raised top layer of the wall, resulting in a height offset that varies depending on the installation location.
  • a negative consequence is that the electrical switch is not accessible at every installation location, since a large height offset makes it difficult or impossible to insert the key card.
  • an electrical switch for use with a key card which ensures that the electrical switch can be inserted and functions in conjunction with the key card even if the height is offset.
  • the key card is inserted into the insertion channel at an angle to the wall.
  • a special support ring has a cantilever arm with a slope so that when the key card is inserted it is guided against a rocker to bring about a mechanical switching movement.
  • the wallpaper compensation is achieved by angle compensation using the cantilever arm.
  • the cover frame is only placed on the support ring, but not fastened, so that the cover frame is arranged at a variable height on the support ring. This means that the cover frame can adapt to a height offset.
  • Another electrical switch for use with a key card and a wallpaper balance is from the DE 44 46 790 A1 known.
  • the key card is also inserted at an angle to the wall into a slot in the electrical switch.
  • a cover frame and a cover assembly are mounted so that they can move relative to a frame that is enclosed by the cover assembly and has a switch lever.
  • the cover assembly and the frame each have conical card insertion openings that overlap one another and thus enable wallpaper to be leveled.
  • the card is bent out of an insertion plane when inserted, so that the key card is stressed each time it is inserted and when it is inserted.
  • the invention is based on the object of providing an electrical switch for use with a key card, which overcomes the disadvantages known from the prior art, in particular enables improved function and/or operation while providing wallpaper compensation.
  • the object is achieved according to the invention by the features of claim 1 in that the cover arrangement and the rocker support are arranged on the key insert by means of a frame-shaped clamping piece in such a way that the distance of the insertion plane from the rocker support is independent of the distance of the cover frame from the support ring.
  • the distance of the insertion plane to the mounting plane in relation to a perpendicular bisector of a support ring opening enclosed by the support ring can thus be variably adjusted in a preferred manner within a tolerance distance.
  • the clamping piece By designing and arranging the clamping piece according to the invention, it is possible to compensate for a height offset between a "low” wall area, which is, for example, in a "raw” untreated state and in which the assembly opening is arranged, and a "raised” wall area, which is, for example, wallpapered. In particular, this prevents a height offset between the cover frame and the rocker support or the cover arrangement.
  • the clamping piece advantageously enables the rocker switch to be mounted so that it can rotate about a switching axis and the rocker support so that it can rotate about an axis of rotation.
  • the switching axis and the axis of rotation expediently run parallel to one another.
  • the switching axis and the axis of rotation are arranged one behind the other in relation to the perpendicular bisector of the support ring opening, so that a compact and space-saving structure is provided.
  • the clamping piece has a straight bearing web for pivotably supporting the rocker support.
  • the bearing web advantageously forms the axis of rotation for the rocker support, so that the axis of rotation is displaced to the same extent when the clamping piece is displaced along the perpendicular bisector of the support ring opening, in particular within the tolerance distance.
