摘要： Electromagnetic drive for data indication includes a shell corelike magnet core, an excitation coil surrounding the magnet core, the magnet core having an inner sleeve-shaped core portion extending through the excitation coil, the inner core portion being formed with an air gap separating the inner core portion into two parts each formed with a magnetic pole, indicating means, and a plunger polarized in longitudinal direction thereof operatively connected to the indicating means, the plunger being freely displaceably disposed within the sleeve-shaped inner core portion and being displaceable from a neutral position thereof to a position wherein the indicating means are effective to provide an indication.
