OOPS.. I changed diagramming method to a physical ascii art diagram without
clarifying it..
Below is 2 switches actuated by a slider which pushes first one switch handle
(left switch) from far left to far right then when pushed past the far left
switch begins to push the right hand switch from left to right.. at it'f full
travel the slider with the 0 (Think Technic Ball from the ball and socket
stuff)would move past the right hand switch so that on the retracting cycle it
would flip the right then left switches.. thus reversing the order of
operation...
Think of it as an ASCII anitmation...

hmm.. I'm working hard on fully groking the pneumatic sequencing page..
although with my moshed net connection, It never finished downloading all of the
images (I gave it 4 hours)... I'd get better performance from a 56k modem..
