ABSTRACT:
A display device has lever mounted display members with their members on one end movable from exposed to eclipsed position to provide a variable display and permanent magnets on the other end to provide for control of the lever by magnetizable cores located rearwardly thereof. A housing structure accurately mounts both a frame which holds the levers and a rear face which holds the cores in three dimensions contributing to the precision of the magnetic control. The cores are mounted projecting from the rear wall of the housing. The forward ends of the cores may be accurately located again contributing to the precision of the magnetic control. The improvement of the magnetic coil means the energizing coils for the windings must be made smaller and for this and other reasons the device may be made smaller from front to back.
