Abstract (en)
A magnetically operated display unit (2) includes a frame (4) with a color, a plate (22) 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 (26) embedded in the plate, a U-shaped ferromagnetic element (8, 17) mounted on the frame so that two tips of the magnet (26) are located between two tips of the U-shaped ferromagnetic element (8, 17), a solenoid (16) mounted on the U-shaped ferromagnetic element and a light emitting diode (12) mounted on the frame. The plate defines a cutout for receiving the light emitting diode and one of the tips of the U-shaped ferromagnetic element. The light emitting diode includes a tip located on a level between the plate and the tips of the U-shaped ferromagnetic element. Two opposite currents are selectively directed through the solenoid. <IMAGE>
