Having trouble with the sleep/wake button on the side of my iPhone 7 Plus after a drop and some water damage that appears to have completely healed over time, with the exception of the sleep/wake button not working. Does anyone have first hand knowledge of the button construction or possibly which assembly the replacement part would come with? I’m assuming it’s a simple contact switch with some slight spring action. Trying to research before tearing into it. Thanks!

get some contact cleaner, there could be corrosion causing your issue on the board.

With some research, I discovered the button switches (the electrical contacts themselves, not the physical mechanical push buttons) are connected to the “iPhone 7 Plus Audio Control Cable and Brackets” iFixit item code IF333-029-1
