This set of exterior case buttons includes the Power/Lock Button, Volume Buttons, and the Vibrate/Ring Switch for replacing buttons with cosmetic troubles.
These are just the button parts visible on the outside of the rear case.
You will need to transfer the wire hinge from your current power button.
The actual buttons and switch that do all the work are attached to the Audio Control and Power Button Cable. If you are experiencing issues with your buttons not working it may actually be the Audio Control and Power Button Cable that's bad.
