Button Pin?

I'm sorry to ask such a stupid question, and I'm Sure the answer is quite obvious, but I am having a hard time finding the name of the button pin for the home kit. I would really appreciate your help.

Apple homekit?
Too few information to give you a solid answer. What library?
Button pin is normally the one you connect a button to.

Welcome.
Maybe we need to see an image of the component :wink:
