  • Product Description

    The Seimitsu PS-14-K snap-in pushbutton closely rivals the ease of installation and tournament quality use of the hugely popular Sanwa OBSF-30 pushbutton.  These are especially easy to install into Fightstick models with a thin metal faceplate. Available in several translucent colors, artwork can also be inserted under the cap of the plunger. and are sought after for their increased customization ability with joystick graphics and LED mods. Seimitsu buttons offer a similar high-quality and responsiveness as a Sanwa, but a slightly different feel and sound as it uses the  Seimitsu PS-14-D Button Micro Switch

    Bundle with MM9-3 High Tension Button Spring and Save

    By default, Seimitsu PS-14-D microswitch requires 0.2 LBF (pounds force) to each button. 

    The MM9-3-25N adds an extra .08 LBF (pounds force), for a total of 0.28 LBF.  The result is a light, but firm button input requirement that accelerates its the button cap's return to neutral. 

    The MM9-3-50N adds an extra .16 LBF (pounds force), for a total of 0.34 LBF, resulting in a much firmer button input requirement that quickly pushes the button cap's to neutral position, ready for the next press.

    This is desirable to some who appreciate using more deliberate input force and a bit less sensitivity than Sanwa's SW-68 offers. Now, you can save 25 cents off the regular price of the MM9-3 series spring when you choose one of the high tension springs from the options list.

    24 vs 30mm

    When processing orders, a frequent mistake we found among new players is choosing the wrong size for action buttons, such as punch and kick.

    Within the fighting game genre, Japanese arcade buttons commonly consist of two diameter sizes: 24 millimeter and 30 milllimeter (mm). In most configurations, 30mm represents your action button.  These are front facing, appearing most prominent on your Fightstick control panel.  Option button, such as "Start", "Select", or more recently "Option", "Touch", or "Share" are usually 24mm.

    UPDATE: Owners of Neo Geo AES Joysticks will need 24mm pushbuttons instead of 30mm (Thanks SRK's DEZALB)

    Below is a visual representation of a common Fightstick control panel.  Throughout this article, we will mark 24mm in green, and 30mm in Orange.

    Checking the Proper Size

    button-30mm.pngAnother way that players can misinterpret the pushbutton size is by measuring the pushbutton plunger.  Have a look at the diagram at right.

    The plunger - the part that you press down to represent an input - is 25mm or a bit smaller in most 30mm pushbuttons.  Often this leads to the conclusion that one needs a 24mm button and not 30mm.

    Similarly measuring the button rim can lead to confusion, as it is intentionally larger than the button hole it is placed in.  You don't want to use these measurements.  Instead, review the button housing diameter, or the hole the button will be placed in.  You can do this with a caliper - a digital caliper is often quite helpful for this and other arcade-related projects.

    Control Panel Configuration

    Most Fightsticks from MadCatz, Hori, Qanba, and similar will use these two sizes.  How the buttons are used will depend on the model joystick that you own. Over time, we'll provide example configurations for specific popular Fightstick models and arcade cabinets using the color key for 24mm (green) and 30mm (orange).  We'll also expand the key for future models if another size is introduced, and we offer for sale.

    1. Hori RAP V upgrades

      Bought a series of items to upgrade my RAP V. Items reached me very fast despite me being over the other side of the globe. Customer service was prompt and swift. Everything installed fine and works great. Description on the website for each single item was extremely clear and helpful. Although this is my first time doing it, there wasn't any nasty surprise as the description was very clear and precise. Finally, shipping fee was very reasonable for the time it took to reach me. Will definitely come back for more. on Jun 16th 2020

    2. Amazing buttons

      My favorite buttons purchased here so far. I think, Seimitsu are very underappreciated and it`s sad. These buttons provide same accuracy and quality as Sanwa do, but have a different feel and they are slightly less sensitive which is a plus for me and many other people. I do like Sanwa as well and don`t mind playing with them either, but accidental presses can happen easily with Sanwa buttons. And I never had this issue with Seimitsu.

      As for these exact buttons type, the color is amazing. Another Sanwa`s minus, for me personally, is that they don`t have translucent purple in their assortment and I really like purple. The picture shows a bluish color but in person these buttons are just regular and very beautiful purple.

      Note that Seimitsu translucent buttons have a white cap under the plunger, so don`t be surprised. This cap is there to place an artwork. The plunger itself is a bit lighter in color than the button`s body, so the artwork could be seen through it better.

      If you are a fan of Sanwa and have no issues with them, stick to Sanwa or try out Seimitsu just out of curiosity. But if something feels off with Sanwa, if they appear feather light sensitive, definitely try out Seimitsu, they can become your perfect buttons for sure.

      They also support foam silencers sold on this site but you will need to cut the tabs on silencers to fit them into the button.

    3. World class for a reason

      I've been using OBSF-30s since I got my TE2 since that's what it came with. Needed purple buttons, so figured it was my chance to test out Seimetsu and see what the difference was like. Frankly, I was shocked how different they feel. A bit less playful, a bit more stiff and serious. In no way directly better or worse, just different - and the important part is they still feel good.
      The only thing I could really knock them for at all is the design of the clip doesn't really fit the TE2 Rev2 snuggly. it feels like it needs another millimeter in there or so to actually snap in, and it's not hard to pop the buttons out if you try. I'm not sure this would be an issue with other sticks, as the TE2 Rev2 has the weird thing with spacers and its plexi, but ... whatever, just know it's not EXACTLY the same as an OBSF.
