The Sanwa and Seimitsu FAQ

The 5x refers to the number of pushes the microswitch can take before it goes out.

Take Sanwa’s OBSF for example, Sanwa’s official website lists OBSF to withstand 1 million pushes/hits while the OBSF-RG can take up to 5 million pushes/hits. I’d assume the Seimitsu buttons’ spec are comparable to the Sanwa’s…

does anyone know if akihabarashop has seimitsu ps-15’s? im in need of them, but they pretty much take the whole site down when they aren’t accepting orders.

Yes, AkihabaraShop do sell Seimitsu PS-15.

How’s it going all? I’m a recent convert to this “Say-meet-soo” company since that silly “Sanway” organization wasn’t treating me very well. I don’t get why all you whippersnappers like them “Sanway” people. Those “Say-meet-soo” folks make some quality product, yessir.

Anyways, since I am a new convert, I’ve got a bunch of questions about Seimitsu products that I can’t seem to find answered or confirmed anywhere else. Hopefully some of you folks could give me a hand.

  1. Recently, I acquired one of those old PlayStation 1 Namco Arcade Sticks. Those flat-topped buttons feel REALLY nice and I wanted to get my hands on some for my Mad Catz Xbox 360 FightStick Tournament Edition. I’ve heard through scattered posts on SRK that Seimitsu does create buttons with a perfectly flat topped plunger, but every Seimitsu button I see on Lizard Lick has a convex plunger and I can’t check AkihabaraShop’s photogallery since their webshop is closed (on a side note, I really hope something’s done about that system!). If Seimitsu does indeed stock flat topped plunger buttons, what product ID would I hunt for?
  2. I understand that the old school PS-14-K translucent snap-in buttons are out of production. If I were to get my hands on a set of them however, would they have a flat topped plunger or a convex top plunger?
  3. I also heard something about being able to place a Sanwa microswitch inside of a Seimitsu buttons. Frankly, I’m a fan of how Sanwa buttons feel, but I must wonder if there was any truth to this statement. If this were possible, what Seimitsu buttons could I do this swap with and would it actually feel like a Sanwa button or would it be something of an in-between or somewhat “off” feeling?
  4. I don’t particularly care for Sanwa joysticks, but one thing that they do with their JLF series of joysticks that I really like is the dual dust washer gimmick. Can I replicate that without any (or heavy) modification to an LS-32-01 with the S mounting plate?
  5. I saw a video from Per on YouTube showing that the LS-40 shaft and dust cover set can be used in an LS-32. For starters, does this impair any functionality or make it feel significantly different? Second, what would I have to order to replace the shaft? I know I’ll need the shaft, shaft cover, dust cover, and probably the actuator, but what about things like a C clip? Must I use the LS-40 E clip or can I use a Sanwa C clip?
  6. Something that I noticed on my first set of Seimitsu parts was that the solid color ball-top (in my case, a red LB-35 [Seimitsu]) was of a different shade of color than its corresponding buttons (again, in my case, red PS-14-GNs). Is this a universal problem across Seimitsu’s products? Could it be remedied by switching to a Sanwa ball-top of the same color? And do the LB-39 bubble-tops suffer a similar problem with their respective PS-14-K/KN buttons?
  7. Finally, regarding PS-14-KN buttons, two things. One, under the assumption that the standard PS-14-K buttons have a flat-topped plunger, would I be able to do a plunger swap with a PS-14-K and a PS-14-KN? Second, I’ve heard numerous people claim that since the PS-14-KNs have a different mounting nut, they are able to perfectly slide underneath the mounting brackets of a FSTE or a HORI Real Arcade Pro 2. Is that statement true or false?

Sorry for the heavy load of questions, but I’d really like to get some answers to these. I’m trying my hardest to get my joystick parts to suit me as best as they can so I don’t have to invest more money than I need. Thanks in advance! :china:

**1. **
Yay for flat girls! I mean buttons!
Always Flat:
Seimitsu PS-14-G
Seimitsu PS-14-D

2.
Convex.
Most specialized colour buttons from Seimitsu are more convex than flat.

3.
Most of them can do a switcharoo.

Could feel like a Sanwa button with a flat top?
Pearl buttons are convex.

4.
You can put Sanwa dust washers on it.
Or the one under the panel a Sanwa and the one above the panel a Seimitsu.
Seimitsu dust washer is not totally flat, it rises at the shaft area.

5.
Answer pending.
Need some help here.

6.
Colour variations are everywhere.
They are batch dependent.
Sanwa is also slightly different.
The only way to get a good mix and match is actually see the items when shopping.

Red stuff:

If I can find my red Seimitsu LB-35,
I will make a picture of it on that panel
with red Seimitsu PS-14-G and Seimitsu PS-14-D buttons.

Answer pending.
Need some help here too.

Some random information:
Seimitsu does not have totally white PS-14-Gs and PS-14-Ds,
not yet anyway.

If someone wants their JLF to feel lighter and more broken in like they are at arcades, try using a LS-33 spring or a Hori EX2 spring. It feels nice :smiley:

does anybody know if a seimitsu ls-56 fit into the TE stick.

If you have a LS-56-01 then I’m sure it will fit in a TE. The LS-56-01 can be screwed on to the same mounting plate as JLF. I have got a LS-56-01 in my HRAP3 so it should work with the TE too.

Takahashi, thanks a ton for the replies! I’ll still have to wait and see if Sanwa microswitches could fit into a PS-14-G button and what I’d need to change my LS-32 shaft into an LS-40 shaft, but seriously, you answered a lot of the questions I wanted answers to. :pray:

I can’t type right now, so hopefully this show you what I want to say.

jdm714, that’s exactly the information I was looking for! Thanks a ton for hunting down some of your old posts regarding this topic which I knew must’ve been asked a lot. I appreciate it man!

Variations of red.

Seimitsu LB-35 Red
Semitsu PS-14-G Red
Seimitsu PS-14-D Red
Sanwa LB-30N Red

The red of the ball top differs from the red of the buttons.
It is very different from the picture.
The red is darker and the ball is even darker.

It is hard to photograph the red with a simple Rollei da8535.

To jdm714: thank you for the detailed post, I don’t know much about pushbuttons, but it looks like I cannot fit PS-14-KN into my HRAP2 SA easily, is this correct?

Thank you for your help!

Seimitsu PS-14-KN fits in HORI Real Arcade Pro. 2 SA.

Has anyone seen this Sanwa before?

As you can see, it doesn’t use the same wiring as the newer JLF sticks. This stick is in an old custom stick that I have. It feels just a little bit tougher to maneuver then the JLF-TP-8T that is in my modded SE stick. Besides the wiring, are there any major differences with this Sanwa stick and the new Sanwa sticks? Should I be looking to replace this stick? (I know that is a subjective question.)

looks like a sanwa clone imo but i could be wrong

thank you for this FAQ

Realyst, it just looks like the person who made the stick just removed the connector from the pcb. Other than that, based on the grainy picture I don’t see any other difference that would lead me to believe it’s another just at all.

Thx. I don’t have a good camera. My cell phone only takes good pictures outdoors and not indoors. It doesn’t look like anything was altered. It seems like that is the way the stick originally was. The restrictor plate does say Sanwa on it but, I think I may just change it anyway. It will be a bitch though the way it the stick was made. Thanks again.

What do you do with the second dust washer? I thought I was sent a 2nd by accident and just used the 1 on top :chat: I didnt know you were supposed to use 2.
