In the design of microwave oven temperature program, combined with the computer switch is used. This switch is different from the usual mechanical switch, switches that are printed on a glass, no moving parts, no punch, very smooth, decontamination easier touch switch. The control panel cover on the surface of conductive film, around which decorate them with ceramic screen printing ink and text. The advantages of mechanical wear resistance, corrosion resistance, easy decontamination. In addition, when designing for glass coloring can be printed on the back of organic coatings due to cannot contact directly on the back, high durability, and choice of ink as well.
