Abstract
The present invention provides a light-emitting control knob capable of consistently maintaining a beautiful design without a problem, such as discoloration or rubbing-off, despite use of a long period because a light-blocking metal plate having light-emitting display windows formed therein is stacked and formed on a top surface of a knob body and of providing a much more beautiful and high-class design than a conventional control knob because surface processing unique to metal can be performed on the light-blocking metal plate. The light-emitting control knob in accordance with the present invention includes a knob body made of transparent or semitransparent synthetic resins which transmit light and a light-blocking metal plate formed of a metal plate stacked on a top surface of the knob body and configured to have light-emitting display windows formed therein.
