  • the control element is arranged on an intermediate element, which in turn is attached or mounted on the carrier plate.
  • the control element is generally provided for setting the operating conditions of the respective household appliance.

  • Microetching has particular advantages in terms of cost and flexibility.
  • the plurality of microholes can be essentially invisible when not illuminated by the illuminant.
  • substantially invisible can be understood to mean that a microhole without
  • Illumination from behind can hardly be perceived by a human eye at a reading distance. It can be seen that this would further improve the appearance of the control device and thus of the household appliance.
