Using the more restrictive criteria that the resistors only come from Radio
Shack retail stores, you can't build a bullet proof four switch mux.
However, I came up with a similar conclusion about the range of resistor
values to use because of the contact resistance of the LEGO switches. In my
three input mux I use 47k, 100k, and 220k values. These only need to be 5%
values.

| I have been keeping an eye on this thread and feel compelled to add my observation and experience; The touch sensors tend to exhibit quite an extended range of resisitance values as they are depressed. I have a couple which start as high as 7k on (...) (24 years ago, 9-Oct-00, to lugnet.robotics)
