It sure is. Thanks.
Using the same pattern (setting up specific switches "backwards"), I can

piston). Again, no need for inter-piston bracing, just the requirement
that a piston simultaneously slide all the switches attached to it.

This says that I can do single pressure logic line with one piston and three (...) (21 years ago, 26-Jun-03, to lugnet.technic, lugnet.robotics)
