iPhone 4S Home Button Ribbon Cable
This is the part of the home button that has the clicking action. If you've got a bad home button, chances are this is the culprit.
The home button ribbon cable does not include the plastic home button itself or the rubber gasket that sits on the display assembly.
Those can be purchased here: iPhone 4S Home Button
