The Sanwa and Seimitsu FAQ


You just pushed it straight down? Or did you twist it open a little? Or…push it into the slot?


I opened the e-clip by just forcefully bending it, then I put it on, then I just closed it with some pliers. Not the best way, I’m sure, but meh. I never took off a Sei e-clip after that.



I got a question, In japan what sticks do they use for 3rd strike sanwa or seimitsu. Cause i’m going there soon and the only japanese stick i have used is the sanwa that came with my hrap. thx


Going off of the Happ website the only shorter buttons they have look to be sanwa OBSN-24 rip offs:

Other than that they are all longer buttons. The only thing that you could try to do if you are really set on happ buttons in a smaller case is mod a competition or something like that. It might be a little tough but it should be do-able. It would be similar to how I modded some competitions to have wood tops, only you would have to cut the threaded area and the spring. The only thing I am not sure of is how good the spring would be after you cut it.

I could give it a try if you want. I do have a left over competition I am not using, though the only problem is I dont have a spring for it. So I could try modding everything but the spring.


I believe 3S is that only main fighting game where Seimitsu LS-32 are used at SBO.



Yeah, best case for me would be to have competitions in there, I have been looking at Korean Crown stuff, but there’s no spring in there, so it won’t feel the same. I was thinking that the hard part would be after you cut the spring and the threaded area, would it hold together well enough? I guess you’d have to use some epoxy or something to hold it together. It’d be awesome of you if you could see if it would hold up after being modded like that! Thing is, the button might feel weird after it’s modded like that, which might defeat the purpose… So yeah, definitely try it out, and keep me posted.


I’ve got a question related to getting sanwa and seimitsu parts so this thread was probably my best choice to post it.

I have a friend who is going to go to Japan to study abroad, and well, since she’s going to Japan, I figured, hey why not have her get me some arcade parts while over there, then bring them back here? Anyways, my question is where do they sell these parts over in Japan? Can you buy them at specialized hobby shops, or do you still have to order parts straight from the company?



Thanks. So for all other fighting games like super turbo , cvs2, and melty blood they use sanwa or does it depends on the game/Arcade?


Go to Akihabara there are a few shops like Mak Japan that stock some parts.

It of course varies, I just mention SBO because it’s the biggest tourney. Just go with whatever you like better.



Which is more durable; microswitches or leaf switches. Does any company still use leaf switches?


Microswitches. That’s why most arcade companies use microswitches instead of leaf switches. They can withstand more activations.


In your opinion, which stick do you think is better a wico bat top or a happ comp. Cause i had brought a few awhile ago and i never got the chance to see whihc one play better.


Never used a Wico before and if I have, I wasn’t aware of it


I figured classic is so much better…plus they sold a set of 2 on ebay a while of ago.


I know this question has been asked before but how easy is it, to take off the mounting plate on a JLF-TP-8YT?


It’s easy. The 4 screws are fit very tightly though, so make sure to use a screwdriver with a large enough head for a good fit, as it’ll require some force. You don’t want to damage the screws.


k thanks.


would Sanwa OBSF-30 fit into a namco arcade stick?


A lot of redundant questions on this board:confused:


Hi I’m new to the whole Custom stick building and was wondering what’s the recommended wood thickness of the top panel minus the lexan/polycarbonate if i’m putting 30mm Sanwa screw-in buttons? Sorry if this has been asked cause i couldnt find the answer.
