Abstract
A magnetically operated display unit includes a frame with a color, a plate pivotably mounted on the frame and including a first surface with a color different to that of the frame and a second surface with a color identical to that of the frame, a magnet embedded in the plate, a pair of bobbins mounted on the frame so that two tips of the magnet are located between two tips of the pair of bobbins, a solenoid mounted on the U-shaped ferromagnetic element and a light emitting diode mounted on the frame. The plate defines a cutout for receiving the light emitting diode and one of the bobbins. The light emitting diode includes a tip located on a level between the plate and the tips of the pair of bobbins. Opposite polarities are selectively induced in the pair of bobbins.
