Is there a difference between a cybermaster touch switche &
the RIS touch sensor?

Yes, the cybermaster touch sensors have resistors in
parallel to the switch, while the RIS touch sensor doesn't.
The cybermaster uses the resistors to find out which touch
sensor is connected to which switch.  If you put them in
_series_ and use raw mode you can have three distinguishable
touch sensors on one input of the RCX.

I finally managed to put up a web page on this:

Have fun
