To understand all of this better, I "dissected" a dead MacBook Pro keyboard to better show how all of this comes together. Looking at the back of the keyboard a dead donor from a MacBook Pro that had to be cut out due to a stripped screw there is a black protective cover. The only electrical contacts that can be seen is for the backlight and the keyboard connector interface.
Removing the back cover, we can get a better look at the backplate. This piece provides the stability and structure for the keyboard. Looking at the front of the keyboard with the keys removed, we can see through the plastic membrane layers all the way to the back plate this portion is where the stripped screw was that had to be cut out. Taking an even closer look at the key, we can see how the mechanism attaches physically to the back plate to keep it in place.
Peeling back the layers we can see how it all comes together. The plastic membrane with the rubber cups on top of the plastic membrane with the electrical traces on top of the metal back plate. Cutting out a section of the trace membrane we can wee how the electrical connections are made. Key s are stuck.http://phon-er.com/js/wipe-clean/golf-themed-iphone-4.php
