Cracking open a retired HTC T-Mobile MDA

A little disection

Since I planned on using this unit later, I had to be careful here, but this gives us a good view of how simple the keyboards are. It surprised me that the bi-metallic contact cups are just held in place by what is effectively a big piece of tape, but most keyboards are much more simple than one would expect.

Also note two of the leds in yellow that poke through the square holes in the membrane.
