Wico leafswitch joystick actuator identification

(1/3) > >>

spidermonkey:
This was being discussed in Timoe's thread titled "[US-CA] Wico 8-way actuator trade for 4-way" in the "Buy & Sell forum but I didn't want to hijack his post so here are the size differences for Wico 4 and 8-way Wico leafswitch joystick actuators. If you're having problems with your Wico 4-way hitting diagonals on occation then you might want to make sure that your stick has the correct size actuator on it because it seems that there are *alot* more of the larger 8-way actuators floating around then there are 4-ways. Many operators didn't really pay attention to what size actuator they used when repairing or replacing a joystick on a game. I say this because I've bought several 4-way Wico leafswitch joysticks on Ebay and quite a few had 8-way actuators on them which causes 4-ways to not be as precise. Apparently operators used whatever they had in order to quickly get the game back in "money making" condition. Alright enough babbelling,here's the sizes...

A Wico 8-way actuator has an outside diameter of 5/8"

RayB:
Cool info! Turns out I have a 4-way actuator on one of my 8-way bodies (not in use, so it was no biggie).

quarterback:
So, just to be clear, the 4-way actuators do not have any kind of step-down at all?

spidermonkey:
That's correct Quarterback. The 4-way actuator has a 1/2" o.d. from one end to the other.(no step down) I now know the reason why the 8-way actuator is stepped down to 1/2" on one end. It's because that end of the actuator fits up into the shaft hole of the joystick about 5mm. The little spring that slides on in front of the actuator keeps it from sliding up any further. You'll notice that if you slide the larger end of the 8-way actuator on first you will find that if you move the joystick in a given direction the actuator will jam up against the wall of the shaft hole before its able to depress and fully engage the leaf switch.This is because there isn't enough clearance between the actuator and the shaft hole that surrounds it so it has to have an o.d. of no more then a 1/2" on that end. I'm probably confusing some people due to my lack of explanation skills. Probably the easiest way to understand what I'm trying to explain is to temporarily put the actuator on backwards and watch the top of it while moving the stick in whatever direction and you'll see exactly what I'm talking about.

Hey, found a pic on Ebay that shows both:
