its prolly too late right now
but the way i would do it
use 2 solenoids
the first solenoid u connect normally
input from ur compressor or tank
the 2 outputs to ur cylinder
then the exhaust goes to the input of ur second solenoid
on the second solenoids main output, you attach a closed loop
(a short piece of tubing, a "T" and another piece of tubing connecting both side of the "t" together)
now since the exhaust is limited it wont shoot all the way up or down
it will be positional...tap whatever button u programmed it too and it will only move slightly
the main problem is the wiring the second and first solenoid have to be wired together off the same spike but u have use 2 diodes between them so u dont want both side of the solenoid firing at the same time
in other words u the exhaust solenoid to fire everytime u push the button but u dont want the main solenoid to be firing both sides
with it firing slower u may be able to use that switch
if u need more info i can draw up a diagram
just ask
