Hello! I have a conundrum on how to download the button model shown in the photo to check the fault inside. I prefer to be sure, because when I try to do it lightly, the mount is quite opposed to me ;)
An old topic but new challenges. There are glass buttons with bellows that are removed by gently levering with a flathead screwdriver on both sides to disengage the two latches located at the keys. Assembly by pushing the pins into the holes to click.
