I bought all of them. 4055 FreeStyle bucket (red), shorter than the Lego Classic bucket 4288, 320 pieces 2494 Lego System bucket (purple), same size as (...)

(...) It sounds like you're saying that the intermediate resistance values happen only for some period of time (short by human standards) while the touch sensor "switches" from "on" to "off" or vice versa. Other people writing in this thread have (...) (25 years ago, 25-Aug-99, to lugnet.robotics)

| | Touch Sensor as a Switch
|

I played around with sensors and wires, and came up with a way to use the touch sensor as a switch. See my post at lugnet.cad.dat.ideas (URL). Unfortunately, even when the touch sensor is pressed, it still has a significant amount of resistance, so (...) (25 years ago, 25-Aug-99, to lugnet.robotics)

(...) That obviously depends on what type of physical design is used for the switch. Some switches are not capable of bouncing the way you describe because there is no impact or acceleration during contact (example: slide switches that move leaf (...) (25 years ago, 25-Aug-99, to lugnet.robotics)

Here a touch sensor is used as a switch. See my post at lugnet.robotics for more details. Electric plates of the same color belong to the same wire. The green plate is the input. The blue plate is the output, in reversed polarity. Cheers, Hao-yang (...) (25 years ago, 25-Aug-99, to lugnet.cad.dat.ideas)
