That is the major component of a button, either one of the volume buttons or the power button. My guess is the power button. The iPhone buttons are made like a clam-shell, this is the upper, side that is pushed of the button. It is just a simple sheet of Kaptan tape (sticker) and a small saucer of metal, which is the click when it is pressed and inverts. As it inverts it contacts the other side of the clam-shell, the contact completes the circuit and the button response is sent to the logic board.
