Abstract

A display element has a disk which rotates on an axis to show its bright or dark sides in the viewing direction.
When the bright side is showing the disk allows passage of light from an LED. When the dark side is showing the disk masks the light from the LED. Preferably, an opaque shroud surrounds the LED and projects a short distance forwardly thereof to help define the cone in which light from the LED
may be viewed in ON position. A side wall or said element projects forwardly of the rotation axis to mask the escape of light on that side transverse to the viewing direction. A
second side wall may be placed on the other side for the same purpose or the adjacent element may provide the second wall.
