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.
