摘要：
A module cover comprising a through-hole for a passage of a key tappet of the key, a light injection region for injecting light from a light source into the module cover, a first light output region for outputting a first portion of the light, and a second light output region for outputting a second portion of the light out of the module cover. The first light output region and the second light output region, and a first light directing portion and a second light directing portion, are arranged on different sides of the through-hole. The first light directing portion directs a first portion of the light to the first light output region and a second portion of the light to the second light directing portion, and the second light directing portion directs at least part of the second portion of the light to the second light output region.
