Shenzhen gekoda film switch Technology Co., Ltd.   

          detail: product features:   introduction of
film switch:
      membrane switch is also called touch type keyboard (MEMBRANE  SWTTCH), whole sealing structure adopts a planar multilayer combinations, is a key switch, panel, mark, the symbol is displayed and foil seal together set machine, electrical integration of the early eighty's the rise of a new type of electronic components, more reliable execution of operating system tasks.
      it has a good waterproof, dustproof, anti oil, anti bacteria, anti corrosion of harmful gas, has the advantages of stable and reliable performance, light weight, small volume, long service life, the panel can be washed, without injury characters, rich colors, beautiful appearance and the like.
      the main products are: plane touching keyboard, keyboard, concave convex stereo sense plane touch keyboard and high performance waterproof type, with light emitting diode (LED) type, with a display window (LCD) thin film switch type.
• EL backlight with the keyboard features: application of light at night or dark environment relatively long time, can long time clearly the text, pattern, keyboard display.

• with the keyboard features light storage: it can use natural light during the day or bright light, the light absorption and storage on the keyboard, stay the night or dark environment emits brightness.

• PCB thin film switch combined with keyboard features: resistance minimum, responsive keys, the operation of uniform stress, long service life and no short circuit phenomenon, and can replace the lining board.
