Abstract
A switch module includes a substrate (), a plurality of switches () provided on an upper surface of the substrate (), first and second light-guiding sheets () disposed to be stacked above the plurality of switches (), at least one first light source () disposed on the upper surface of the substrate () to illuminate the first light-guiding sheet (), at least one second light source () disposed on the upper surface of the substrate () to illuminate the second light-guiding sheet (), and a switching-control device () configured to switch between lighting of the first light source () and lighting of the second light source (). First and second displays () are respectively provided on a surface of each of the first and second light-guiding sheets (). When the first light source () is lighted, the first display is displayed, and when the second light source () is lighted, the second display () is displayed. By switching between lighting of the first light source () and lighting of the second light source (), either the first display () or the second display () can be selectively displayed.
