为什么我的继电器开关按钮松开？

嗨，这里有菜鸟。几周前刚开始用微控制器，所以我希望你能为我澄清一些事情。我使用的是PIC16F1619的好奇板和一些外部部件，比如继电器、LED和开关，看看能做什么。我很感兴趣的是，你可以使用一个开关来选择多个功能，所以我设置了一个锁存继电器，在第一个按钮推送一个方法，然后把另一个放在同一个按钮的下一个按钮上。我自己无法理解这一点，所以我修改了我发现的一段代码。WEB，可能是完全错误的方式，但我注意到，只有当我松开按钮时，继电器才会切换。我不相信这是纯粹的阿德反弹问题，因为它是如此的一致和可重复的。你能告诉我下面的代码，为什么会发生这样的事情？因为我不明白为什么当按钮被按下时，继电器就不会扔。我对此有一些逻辑上的反驳吗？顺便说一下，我现在正在通过GooCum和其他教程工作。谢谢。

    Hi there Newbie here. Just started with microcontrollers a few weeks ago so I hope you can clear a few things up for me. I'm using the Curiosity board with the PIC16F1619 and a few external components such as a relay, LED's and a switch just to see what can be done. I'm very interested in how you can use just one switch to select multiple functions so I set up a latching relay to throw one way on the first button push then throw the other on the next button push of the same button.

I could not figure this out on my own so I modified a piece of code I found the web, probably it's the incorrect way to do it altogether BUT I've noticed that the relay seems to switch only when I let off of the button. I don't believe it is purely a de-bounce issue as it is so consistent and repeatable. So can you tell me from the code I have below, WHY this is happening? Because I don't see why the relay doesn't just throw when the button is pushed. Do I have some of my logic backwards on this? BTW, I am working through Gooligum and other tutorials at the moment.

Thank you.
