| | | | (...) I have tried this method too, and as you say in your text, it is plagued by the rubber contacts whose value goes down as more pressure is applied to the switch. I measured resistance of several touch sensors while applying a very progressive (...) (21 years ago, 11-Sep-03, to lugnet.robotics.rcx)

| | | | | Here is a chart showing the variation of contact resistance of several touch sensors while pressing button very progressively. (URL) There are huge differences between various sensor Lightly pressed touch sensors have contact resistance in the 2 to (...) (21 years ago, 11-Sep-03, to lugnet.robotics.rcx, FTX)
