You are right - I should have looked there first - I was in a rush and
thought about your pictures after I posted.  

It looks like a few force sensitive switches with series resistors to
give a few zones as you squash your foot down.  I am still puzzled by
why it uses both connections on the stereo plug.

Now I will just have to take it apart!
