But it IS true, and that's why the 6 input mux at:
<http://www.daimi.au.dk/~mic/speciale/RCX/>
has some problems. Find out for yourself by putting a meter across a touch
sensor. The resistance changes from about 1K to 470R when pressed depending on
how hard it is pressed.
Michael Gasperi's server is down (or my server can't find it) and there is a picture
of the touch sensor internals...I wonder if there is actually a metal contact
or if its one of those rubber thingys...

| (...) Yes, it's one of those rubber things. Cybermaster's touch sensors come with a translucent housing, so you can see the inards quite nicely. There's a resistor across the two contacts, too. Tilman -- Did you check the web site first?: (URL) (25 years ago, 24-Aug-99, to lugnet.robotics)
