ELECTROMAGNETIC INDICATING APPARATUS FOR DISPLAYING A PLURALITY OF DISCRETE INDICIA IN RESPONSE TO ELECTRICAL ENERGIZATION COMPRISING: A MAGNETIC ROTOR HAVING DIAMETRICALLY OPPOSED POLES ROTATABLY SUPPORTED FOR DEFLECTION ABOUT THE AXIS THEREOF TO A PLURALITY OF DISCRETE ANGULARLY SPACED POSITIONS, ONE OR MORE ELECTROMAGNETIC COILS, THE COILS BEING POSITIONED ABOUT SAID ROTOR AXIS WITH THEIR AXES EXTENDING RADIALLY IN A DIRECTION SUBSTANTIALLY PERPENDICULAR TO THE AXIS OF SAID ROTOR, A SHARPLY DEFINED STATIC MAGNETIC LOCK MEMBER CONTIGUOUS TO THE AXIS OF EACH COIL AND EXTENDING RADIALLY IN A DIRECTION SUBSTANTIALLY PERPENDICULAR TO THE AXIS OF SAID ROTOR, AND MEANS TO SELECTIVELY ENERGIZE ONE OF SAID COILS AT A TIME WITH A ELECTRICAL SIGNAL OF EITHER OF TWO OPPOSED POLARITIES, SAID MAGNETIC ROTOR BEING DEFLECTED TO A FIRST ANGULAR POSITION IN ACCORDANCE WITH THE POSITION OF THE COIL ENERGIZED AND THE POLARITY OF ENERGIZATION, AND SAID ROTOR UPON DE-ENERGIZATION OF SAID COIL ASSUMING A DISCRETE ANGULAR POSITION ADJACENT TO THE FIRST ANGULAR POSITION BY THE MODIFYING INTERACTION OF THE ROTOR AND THE STATIC MAGNETIC MEMBER EXTENDING ALONG A LINE CONTIGUOUS TO THE AXIS OF THE PREVIOUSLY ENERGIZED COIL, WHEREBY EACH COIL AND ASSOCIATED STATIC MAGNETIC MEMBER PROVIDES TWO DIAMETRICALLY OPPOSED POSITIONS FOR SAID ROTOR.
