Abstract
The invention proposes a key module for a key of a keyboard. The key module includes a module base, a module cover that can be coupled with the module base and a key tappet for coupling a keycap that is translucent in at least one symbol section. The module base includes at least one through-hole between a bottom section of the key module and the module cover. The module cover includes a section that is translucent for the light from a light source. The light source is a color-changeable light source for backlighting the symbol section of the keycap. The translucent section of the module cover is aligned with the at least one through-hole when the module cover is coupled to the module base.
