Glorious!!! I modded two of my Versa-Micros as you suggested to have the actuator arm on them. Works great!
The only thing I would add to your tutorial on how to do it is to hook up a multimeter and test that the switch still functions at the setting that you choose with the allen wrench. I made the mistake of going too far, putting the whole dang thing back together, only to have to have to take it all apart and try again. I managed to destroy one of the switches in the process, but that's okay! I have four of them and I only need two for this purpose.
2 Versa-Micros + J-Stick/JLW + Seimitsu LB-30 ball-top = most excellent modern take on a Defender/Stargate two-way stick! The throw feels about right. Will have to be quite recessed to get the height off of the panel correct.
I'll just need to dremel some plastic away on the stick and some of the mounting plate, get it mounted on a test control panel, and get a button in the right spot relative to it and I'll be set.
Thanks for the tutorial!!! If anyone is looking at doing this, it takes less than 5 minutes to mod a Versa-Micro switch like this.
