ELECTROMAGNETIC INDICATOR HAVING A ROTOR DISPOSABLE IN DISCRETE POSITIONS ABSTRACT An electromagnetic indicator has a stator carrying a stationary reversibly magnetizable core, and a rotor including a display disk and rotary cylindrical magnet. The magnet is permanently magnetized with two poles each angularly spaced apart less than 180° at one side of a diameter of the magnet which also passes through the radially located core. Stop elements carried by the stator and core are engaged in each stopping position of the rotor when one of the magnet poles is attracted to, but held spaced from the magnetized core. The poles can be located to effect a turning range of the rotor from 120° to 250°.
