Patent ID: 7592561

Claim:
An illuminated switch comprising: an operation knob that includes an operation surface; a light source that emits light beams having an optical axis in a predetermined direction; a first light guide member that is provided in the operation knob and guides the light beams emitted from the light source to the operation surface; and a second light guide member, which is provided between the light source and a light incident surface, and converts the light beams emitted from the light source into parallel light beams, wherein the first light guide member includes the light incident surface at one end of the first light guide member formed of inclined surface that refracts light beams entering along the optical axis in a first direction, a reflection surface that reflects light beams refracted at the light incident surface in a second direction different from the first direction, and a light exit surface at the other end of the first light guide member that transmits light beams reflected by the reflection surface, wherein the second light guide member includes a convex lens portion at one end thereof facing the light source, and a light emitting surface perpendicular to the optical axis at the other end thereof facing the light incident surface of the first light guide member, and wherein conical surfaces are formed on side surfaces of the second light guide member, and reflect light beams entering from one end of the second light guide member through a light receiving surface, which becomes broad from the edge of the convex lens portion, toward the light emitting surface.
