Joystick Mechanics
mgb:
One big difference on a stick like that used in the Ms Pacman (if it was original) is that it used a rubber centering grommet rather than a spring.
you can see an exploded view in the manual on page 51.

I have toyed around with the idea of getting u360s, but I really like old school conventinal joystick like my JLWs (though they are a bit clicky)
I have a customers Ms Pacman right now and I will be taking apart the stick at some point to clean and adjust. let me know if you need any pics or measurements.
Woodshop Flunky:
Thanks MGB! Please post any pics you can take of the joystick. I'm sure a lot of us here are fairly ignorant of the different joystick mechanics.
The rubber grommet sounds interesting. I really like the U360 for many reasons, but I can sense/feel/hear (not really sure which or all) the mechanics of the spring and the bearing surfaces. Some of the other games I've played seem to have none of this. The clicking of the microswitchs doesn't bother me.
Woodshop Flunky:
Just took a look at the exploded view of the joystick in your link. That rubber grommet really is a different animal than what I've seen with the spring setup in my U360.
Thanks again!
mgb:
From what I know, most of the older sticks used a rubber centering grommet similar to that.
I know the wico leafs did and I have a pair of Rotary sticks from a Heavy Barrel and they have a centering grommet too (bassically built just like Wicos, maybe thats who made them?)
But when those grommets get beat and they tear away then they are pretty bad.
I'll try and get some pics, what not from that stick as soon as I can

I meant, how it is designed to do that?...or is it a trade secret?

The switches (non-blade microswitches) just sit VERY close to the actuator. The shaft then travels very short after actuation to the edge of the square gate hole.
