摘要： A method of constructing assemblies for keypads with different key layouts using substrates each having the same pattern of electrical-contact regions formed thereon and domed contact elements, the method including the steps of selecting a first design of key layout; providing a first insulating layer having a plurality of apertures dependent on the first design; mounting the contact elements to confront corresponding electrical-contact regions of a first of said substrates with the first insulating layer disposed therebetween, each of said apertures being in register with a said contact element, thereby to produce an assembly having the first design key layout; selecting a second design of key layout, the second design being different to the first key layout; providing a second insulating layer having a plurality of apertures dependent on the second design; and mounting the contact elements to confront corresponding electrical-contact regions of a second of said substrates with the second insulating layer disposed therebetween, each of said apertures being in register with a said contact element, thereby to produce an assembly having the second design key layout.
摘要翻译：一种使用具有与其形成的相同图案的电接触区域的基板和圆顶形接触元件来构造具有不同键布局的键盘的组件的方法，所述方法包括以下步骤：选择键布局的第一设计; 提供具有取决于所述第一设计的多个孔的第一绝缘层; 安装所述接触元件以与所述第一绝缘层相对置的第一所述基板的对应的电接触区域，每个所述孔与所述接触元件对准，由此产生具有所述第一设计键布局的组件; 选择键布局的第二设计，第二设计与第一键布局不同; 提供具有取决于所述第二设计的多个孔的第二绝缘层; 以及安装所述接触元件以与所述第二绝缘层相对置的第二所述基板的相应的电接触区域，每个所述孔与所述接触元件对准，从而产生具有所述第二设计键布局的组件。
