Abstract: A cabin illumination device is provided on a wall surface of a cabin of a vehicle and illuminates the cabin and includes: a light source disposed to emit light away from the wall surface; and a reflective member disposed to intersect a light axis of light emitted by the light source. The reflective member includes a first protruded surface disposed to intersect the light axis of the light source, and a portion of the reflective member is sloped downward in a direction away from an intersection of the light axis and the first protruded surface.

Abstract: A switch device is a switch device provided in a vehicle. The switch device includes: a panel that receives a user operation; a cover that displaces between an open position in which the panel is exposed and a closed position in which the panel is covered; a capacitive sensor electrode provided on an opposite side of the panel relative to a cover side of the panel; a cover state detector that detects a state of the cover indicating the open position or the closed position; and a controller that determines, based on an operation signal output by the capacitive sensor electrode, whether an operation has been performed on the switch device. The controller changes detection sensitivity of the capacitive sensor electrode depending on the state of the cover detected by the cover state detector.
