A display element comprises a stator housing with a front aperture and a rotor electromagnetically rotatable to assume three or four rotary positions. At each rotary position a different area of the rotor is seen through the aperture. Two or three of the areas of the rotor are translucent. Apertures in the stator housing and registering apertures in the rotor allow the translucent areas to be illuminated by lighting placed to the rear of the stator housing.

Display element with back lighting

A thin disk contrastingly colored on opposite sides is rotatably mounted to rotate about its diameter. A permanent magnet on the disk allows the disk to be driven by a pair of reversibly magnetizable cores. One of the cores is bent to provide a stop which limits the rotation of the disk in either direction. The two limiting positions correspond to the display of the contrastingly colored sides in the viewing direction.
