I’m considering buying some concave buttons for my Mad Catz TE. It looks like there are a lot of 30mm semitsu options and I’m not sure which is best for the TE. I’m guessing I need to stick with snap-ins? Which model is generally recommended?
Any other comments on concave vs. convex buttons are welcome, as well. Thanks!
There are no concave buttons that I know of that will fit for sure. You may want to email the company that sells these.
Thanks for the link, I’ll check it out. I met somebody who I’m almost positive had a TE with concave buttons, I asked him which brand they were (semitsu) but didn’t think to confirm that he was using a TE>
Yeah if you want to get happ concaves, you have to get a discontinued short barrel version and you have to cut away at a lot of the plastic in the center of the stick to make room for the switches.
I think Seimitsu is all convex. And you could do snap in or screw in, but the first button on the bottom row will be hard to screw in because of the mounting bracket for the joystick.
Seimitsu also have flat top buttons. As for the screw ins put the screw under the panel and the stick mounting bracket first then screw in the buttons.
I believe sanwa sells concave buttons or Happ. (I don’t recall seimetsu selling concaves 
) And the buttons can be either screw ins or snap ins. Doesn’t matter as long as they have that 30mm size. I find screw-ins to be easier to install and much more secured. Snap-ins can be a pain to install and if you were to have an arthong plexi glass it can snap the plexi. Screw-ins for the win. No differences in price.
Last I checked, no Japanese company sells concave buttons.
Sanwa does not sell 30mm concaves. I looked at a few catalogs.
You cannot use Sanwa screw ins for the LP button without modifying the screw nut. The joystick mounting plate gets in the way of the nut, you have to dremel away a part of it. Small nuts on Seimitsu screw ins work fine.
If you are willing to cut away at the plastic center of the TE the buttons I linked you to should fit, but I have no knowledge about the button quality.
The person that told you he had seimitsu concaves was misinformed. I’ve never seen a concave seimitsu 30mm button in the catalog.
Yenox buttons with switches replaced with cherries might also fit if you cut away at the plastic.

Noone told me about seimitsu concaves. I just implied “I don’t recall Seimitsu” owning any product line of them because the owner of this post mentioned he/she didn’t mind about seimitsu then asked which of the two are better, concave or convex?
But yeah there are no concaves for sanwa buttons. I wasn’t too sure with my answer so I’d thought I would add “I believe”.
Thanks for the info though. I had no idea the screw in Sanwas for the LP button wouldn’t fit without any slight custom modifications.
Pretty sure that Seimitsu does not have concave buttons. Or at least, they aren’t listed on their site.
So I know this thread has been dead for awhile, but I was wondering if anyone has yet tried the Yenox buttons with Cherry switches.
been done, For the most part switches that works on Happ, IL and most ultimarc push buttons will work on Yenox, that includes cherry switches.
Now please do not hijacked necroed threads, this is looked down on.
OK, no worries. I didn’t want to start a new thread, though, and I couldn’t find another relevant one. I wasn’t concerned about the microswitches being interchangeable; I was concerned with the quality of the button.
Do the Yenox buttons have enough clearance without a Dremel party? Sounds like a fair alternative for people wanting Happ buttons.
You’ll still have to Dremel or sonic-cut the middle frame/layer. They’re short enough to fit in without doing anything to the metal plate.
has any company come up with concave buttons for the SE fightstick yet?
No. Keep in mind that the SE just uses 30mm buttons, which is standard in Japanese markets. There are no buttons that are actually “designed” for the SE Fightstick.
That being said, there are no buttons available that fit 30mm holes that are concave.
thanks
Concave buttons are American-style.
The majority of companies that still make arcade parts are copying Sanwa-style buttons which are all convex.
People that want concave buttons or American style are in the minority and are generally retro-gamers with American-style cabinets or want to spend less money and recapture part of their nostalgic youth. (I’m in the minority here despite being an older game because I NEVER liked American-style parts and joysticks even when we had thousands of arcades in the US; I think the Asian parts are better and generally more responsive.) The fashion is to copy and make what’s most popular and right now that’s the Japanese arcade style parts.
Most of the concave buttons out there are all in the “American-style” (ie, Happ and iL buttons) and way too long to fit into the majority of joystick cases being manufactured now.
You’d have to find an old style MAS joystick case OR make your own case to fit these buttons to begin with because they’re too long and it’s awkward to mod them for shorter production cases. They also have the issue of being a different diameter than the Japanese buttons. The majority of non-Japanese/non-Asian style buttons are 28mm. Korean buttons are an exception in that they are 28mm but still short like Japanese-style buttons. However, to my knowledge they don’t manufacture concave buttons in Korea, either. Sanwa, Seimitsu, and their clones are all 30mm and convex (bulge out at top slightly) or are flat on top…
