Illumination Only and Colored Illumination for Models with LEDs
With illumination only, the color of the lighted surface is the same when the LED is lit and when it is not lit.
Example: Red Illumination
With colored illumination, the color of the lighted surface is white when the LED is not lit and the LED emits another color when it is lit.
Example: Red Illumination
Ordering: For colored illumination, order the Pushbutton, Case, Lamp, and Switch separately.
