PROBLEM TO BE SOLVED: To provide a switch module enabled to make a display clearer while maintaining a superb operating feeling. SOLUTION: The switch module 2 is provided with a substrate 4, a sheet switch 6 fitted on it, a first and a second light guide plates 8, 10 arranged further superposed on it, a first and a second light sources 12, 14 irradiating light on the first and the second light guide plates 8, 10, respectively, and a change-over control portion 15 changing over lighting of the first and the second light sources 12, 14. The first and the second light guide plates 8, 10 have a first and a second display portions 22, 24, respectively, on each rear face. When the first light source 12 is lit, the first display portion 22 emits light. When the second light source 14 is lit, the second display portion 24 emits light. With this, the first and the second display portions 22, 24, can be changed over for display, as the first and the second light sources 12, 14 are changed over to be lit. COPYRIGHT: (C)2011,JPO&INPIT
