Abstract：In view of the existing popular KBZ series of low voltage feed switch，its showing function is insufficient.  Aiming at this problem，liquid crystal display technology was applied in the KBZ series of low-voltage feed in on-off state. The ATMEL series of monolithic integrated circuit was selected as the design core of the main body. The JM1286A graph lattice liquid crystal display module was used as the display parts. The test result indicates that the Chinese character liquid crystal state display realizes the data real-time，fast，accurate and guarantees each kind of parameter high accuracy，the high stability. The demonstration of true-time operation can be carried on  by the man-machine. It has merits of half intellectualization. It not only reduces enterprise's production cycle and the production cost，moreover causes the demonstration of the Chinese character to be more direct-viewing.
