Abstract
A dial switch disposed on a front surface of a control panel is surrounded by a colored ring which is visible from a front side of the control panel. Behind the front surface of the control panel, an ornamental prism made of a transparent material and a light source are disposed. A colored layer is formed on the rear surface of the ornamental prism so that a ring surrounding the dial switch is visible as a colored ring. The colored ring is visible through the transparent ornamental prism at the daytime and is visible by illumination of the light source in the nighttime. Since no light leaks bypassing the colored layer, the ring is perfectly colored. Since only the flat rear surface of the ornamental prism is covered with the colored layer, the ornamental prism can be manufactured in a simple process.
