    • A foolproof polarity indication for poled electronics parts or devices to be mounted to a printed circuit board assures that the poled electronics parts and/or devices are correctly mounted with respect of their polarities to meet occasional requirements dependent on different specifications. Each pair of terminal holes is allotted to a given poled electronics part or device. Two symbols representative of such electronics part or device are arranged side by side on either side of a line drawn from one terminal hole to the other terminal hole. The poled electronics part or device symbols are of reversed polarities. This dual symbol arrangement is effective to draw a worker's attention in the mounting of electrode components in terms of their polarities. When extra components or dummy components are combined with such a poled component, they are encircled by a boundary line, thereby showing the correct polarity direction of the poled component with respect to whether it is enclosed or not.
    • 用于安装到印刷电路板的极化电子部件或设备的绝对极性指示确保极化的电子部件和/或设备相对于它们的极性被正确地安装以满足取决于不同规格的偶尔要求。 每对终端孔分配给给定的极化电子部件或设备。 代表这种电子部件或装置的两个符号并列地布置在从一个端子孔到另一个端子孔的线的任一侧上。 极化的电子部件或器件符号具有相反的极性。 这种双重符号排列在使用工作人员的极性方面有助于注意电极组件的安装。 当额外的部件或虚拟部件与这种极化部件组合时,它们被边界线包围,从而显示极化部件相对于是否被封闭的正确的极性方向。
