ABSTRACT OF THE DISCLOSURE MATRIX PRINT HEAD A matrix print head is provided with electromagnetic circuits coordinated to individual dot-print elements (10), where the dot-print elements (10) are attached in each case to spring armatures (11). The armatures are in each case disposed opposite to a coil core (12) of an electromagnetic coil (14), and the armature (11), the coil core (12), a back plate (16), a permanent magnet (17), and a yoke plate (18) form a main-series magnetic circuit (19), where the armature (11) rests in its rest position on the coil core (12). In addition, a shunt magnetic circuit (20) is coordinated to each main-series magnetic circuit (19), where the shunt magnetic circuit is formed by the back plate (16), by the permanent magnet (17), the yoke plate (18), and by a shunt ring (21). The magnetic reluctance of the shunt magnetic circuit (20) is kept substantially constant over temperature ranges in order to save expensive tuning apparatus, to balance possible production tolerances, and to improve the dynamic part of the pin-print head in an optimum way relative to magnetic force and expended energies. The permanent magnet (17) of the main-series magnetic circuit (19) is dimensioned substantially lower than the corresponding electromagnetic coil (14).
