如何在 TikZ-circuits.ee.IEC 符号中获取可选参数？

Question

晚上好，

因此在下面的代码中，我有“新的”电路符号，名为“转换器”。

简而言之：我使用“通用圆圈”，但我没有向他展示；我在其上画了一个 pgf 矩形，至少画了一条“十字线”。我不知道这是否是获得这样的电路符号的最佳方法，但我没有更好的想法来绘制它（没有“通用矩形”）。

好的，第二个是关键字‘change’，它改变了两个文本标签（图中：“AC”<--->“DC”）。

所以我的问题是：

我希望将符号内的文本作为可选参数，例如

• 转换器={x}{abc}

• 转换器={AC}{DC}，如图所示。

但我不知道如何进行编程。

你有什么想法吗？（你对总体改进有什么建议吗？）

感谢您的阅读和关注。

Answer 1

我将“更改”替换为“从...转换”和“转换为...转换”。
