怎么使用按钮开关作为三向开关

这是吉他踏板吗？
或用于交流电源？



以下为原文

        Is this for a guitar pedal? or for AC power?

以下是连接三路开关对的基本方法
旅行者系统
在旅行者系统中，也称为“共用”系统，电力线（热，以红色显示）被馈送到其中一个开关的公共端子;
然后，开关通过一对称为“旅行者”的导线相互连接，并且灯连接到第二开关的公共线，如图所示。
加州3路
“California 3-way”或“Coast 3-way”连接从未将灯座外壳连接到线路（热）端子。
可选的附加灯可以在A端作为指示灯连接，或照亮长的走廊。
可选的插座可以连接在B端子，因为该端子始终处于带电状态。

以下为原文

        Here are the basic ways to wire up a three way switch pair
Traveler system

In the traveler system, also called the “common” system, the power line (hot, shown in red) is fed into the common terminal of one of the switches; the switches are then connected to each other by a pair of wires called “travelers”, and the lamp is connected to the common line of the second switch, as shown.
California 3-way

The “California 3-way” or “Coast 3-way” connection never connects the lamp socket shell to the line (hot) terminal. An optional additional lamp can be connected at Terminal A as a pilot lamp, or to illuminate a long corridor. An optional receptacle can be connected at Terminal B, since that terminal is always live.

这适用于交流电源。



以下为原文

        This is for AC power.

SPST开关不能以三向配置工作。
ON-ON风格的SPDT可以工作。
您将需要两个这样的开关，您基本上将NC连接到NC，NO连接到NO，然后一个公共变为输入，另一个变为输出。



以下为原文

        The SPST switch will not work in a three-way configuration.  A SPDT in an ON-ON style will work.  You will need two of these switches where you basically connect the NC to NC and NO to NO, then one common becomes the input and the other common becomes the output.

客户所看到的脚踏开关将无法处理交流负载，它们可以用作机械继电器或固态继电器的控制器，在这种情况下，两个SPDT以三路开关配置连接，如John所提到的那样。
此时，您可以使用两个瞬时开关作为微控制器的控制信号。
按下时，如果电路打开，关闭，如果电路关闭，打开，在这种情况下可以使用瞬时开关，但根据他们的问题，他们不太可能寻求一个嵌入式项目
。



以下为原文

        The footswitches the customer is looking at will not be able to handle AC loads, they can be used as controls for mechanical relays or solid state relays, in which case two SPDT wired in a three way switch configuration like John mentioned would work.
At that point you can just use two momentary switches as control signals for a microcontroller. When pressed, if the circuit is on, turn off, if circuit is off, turn on, in that case a off-momentary switch can be used, but based on their question they’re unlikely to be seeking an embedded project out of this.
