Self-illuminating panel switch |
摘要 |
In a self-illuminating panel switch, a key top is supported by a front panel. The key top has a rear surface on which a character area is printed with one of a dark color or a light color, and the background area is printed with the other of a dark color and a light color. Because the printing is made on the rear or inner surface of the key top, the ink is free from wear or removal.
