    • A key board of mobile phone applied in key circuit of mobile phone is provided. A first electrode, a second electrode and a third electrode are disposed on a printed circuit board (PCB), the second electrode is disposed around the first electrode in circular form, tooth profile structures disposed matched with the third electrode are extended from an outer side of the second electrode, the third electrode is connected with the first electrode, the setting can be applied to various types of keys. The key board of the mobile phone can not only be applied to the dome keys, but also the carbon granule keys. If customers need different designs of keys, the new keys are needed to be redesign, and a new main board is not necessary to design, which greatly saves development time and lowers the cost.
    • 提供应用于手机钥匙电路的手机关键板。 第一电极,第二电极和第三电极设置在印刷电路板(PCB)上,第二电极以圆形形式设置在第一电极周围,与第三电极匹配的齿形结构从外侧延伸 的第二电极,第三电极与第一电极连接,该设置可以应用于各种键。 手机的键盘不仅可以应用于圆顶键,还可以应用于碳粉钥匙。 如果客户需要不同的按键设计,需要重新设计新的按键,而不需要设计新的主板,大大节省了开发时间并降低了成本。
