Segmental readout device having improved magnetic circuit components

摘要: A segmental readout device includes a support plate carrying seven rotatable magnetized indicator members in spaced array adjacent to front having openings expose the members. magnetic back has forwardly extending cores integrally formed with and cylindrical electromagnetic coils for actuating One group of lateral magnets diametrically opposite poles oriented oppositely from similar another centered magnets. Coils associated are wound Rotational axes perpendicular The orientation winding effectively isolates circuits each other so that it limits ability one magnet cause rotation any magnet.
