Progress is mixed. Screenprinted conductive paints do not have the durability we require. Those have been ruled out.
The conductive rubber pads have a tendency to crack the plastic they're stuck to, probably because they're a bit too rigid and apply pressure at their edges. The microswitch test is the only one going perfectly smoothly. I have a motor with a cam pushing a pencil so the rubber end actuates a key onto each surface. They must have done around 100,000 cycles or more on each of the three test systems. That ends this progress report. Back to your usual programming... Dave no.site.at.present :/
