While it's the worst photo imaginable for detailed analysis, it seems to me the the push buttons on this programmer are the touch switches Serge played around with in the late 70s (last time I saw them). There were a bunch of them laying around at one point, but the only system i've ever seen them in was Gary Chang's - and they are still there and functional (2 million years later).
These may not be them (again, picture is shite), but they do resemble the touch switches.
