Be careful with the three position cylinders though. They do not behave exactly the same as two 2-position cylinders stacked back to back. See this post here for details: http://www.chiefdelphi.com/forums/sh...75#post1276175

Thank you, that's very helpful. So the holding force in the middle position is quite low then.
In that case, I might just switch to two stacked cylinders.
