Abstract
The present invention relates to a display device with a movable element. The movable element is driven between ON and OFF positions by switching the polarity of a first high remanence magnetic core. A reed switch is located in the flux path of the switchable magnetic core and of a second magnetic core such that the reed switch assumes open and closed states. The reed switch is connected so that one state turns on or exposes a light source and the other state turns off or masks the light source.
