Are you sure your multimeter is up to the task? I have measured numerous touch
sensors (from 1.5, 2.0 and cybermaster), all of them have a high value when not
pressed (open for RIS 1.5 and 2.0, 10 to 15KOhm for Cybermaster that have a
parallelded resistor). When pressed all of them decrease to about 500 Ohm, the
variation occurs on a 0.05 mm course. See the variation curve here:
