  • Product Description

    Sanwa's highly anticipated addition to their popular arcade button lineup comes in the form of 30mm translucent buttons! Available in multiple colors, these still feature the feather-sensitive, competition-ready SW-68 microswitch and look fantastic in a 6 or 8 button setup.

    Silencer is our 1mm-thick foam washer that helps to dampen the loud sounds common with tapping on the button plunger.  It conforms to the internal housing of many Sanwa or Seimitsu-style 30mm pushbuttons.

    Silencer Installation

    installing the Silencer foam pads into a Sanwa or Seimitsu pushbutton is straightforward.  Place the washer - plastic film side down - into the button housing.  Align the small tabs so that they stick out of the holes on each side of the housing.  For Seimitsu PS-15, and Hori Hayabusa low profile pushbuttons, snip the tabs off with scissors and place into the housing.

    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. great stuff

      top of the line great stuff. on Jun 22nd 2024

    2. I love ordering from you guys.

      Everything I order is top quality and never disappoints! on May 23rd 2024

    3. Better than expected...

      Ordered 8 of these before they ran out completely. Did not encounter any of the other review issues such as fragility of snap-in tabs at all. All in all, I'm very impressed with these Sanwa buttons and the mechanics of each part within the buttons. Every part has a correct placement so you can easily tell if it's not reassembled correctly such as the button cap not sitting flush; this is noticeable by a single small plastic tab that seats itself into the inner white plastic part which isn't seen below the clear cap and casing.

      Getting my art to sit perfectly isn't too difficult, and I found it fun and easy. A simple small flat screwdriver allows you to push in the white inner plastic tab and shove the entire inner cap parts out so you can add your art, either to the top of the cap lid or directly inside the cap casing. Take note of the cross-direction plastic underneath the inner button lid as this must be flush with the button inner plastic part when re-seating.

      Arrived fast and well packaged, 8 buttons and a smaller 24mm Start button. I definitely plan on buying more internal parts here. Enjoy!

    4. Solid product

      I love these for custom artwork. 10/10 would use again. on Dec 22nd 2020

    5. Broke easily

      I'd had my hitbox customized for maybe two days when I noticed this button had spun a noticeable amount. Opened the Hitbox to see one of the two clips you squeeze to remove the button had snapped off. Haven't had issues with any other pushbuttons purchased from Focus Attack on Dec 22nd 2020

    6. The best

      The best highest quality buttons on the market, just wish they kept them in stock 24/7 on May 19th 2020

    7. 'Clear'ly Pefect!

      If you want to show off your artwork in full glory, these are the buttons to do it with your fightstick! Easy to insert the art inside the buttons, but do be careful, they are fragile. on Dec 25th 2019

    8. Top-of-the-line quality, as expected from Sanwa

      Perfect replacements for the set of cheaper Crown buttons that my stick's previous owner elected to install. Requires a little more force when pushing, which I personally prefer to more sensitive switches.

      As for the ordering process, the buttons arrived with two sets of artwork in less than 10 days, so I must say I'm very impressed with FA's shipping service, five stars.

    9. Great Buttons!

      These buttons are great to make full use of the custom art for your fighstick. Just be careful when installing them because the tabs are very fragile. But the buttons work and look great. on Apr 29th 2019

    10. Good, but Fragile

      They feel as other Sanwa OBSFs do, with the added bonus of a clear button housing that blends with a lot of stick designs and artwork caps that lets you insert your own artwork. However, I find that they are quite consistently brittle; when I removed some from my stick, 4 of them had broken tabs, and a couple more had tabs that nearly snapped. Aside from this, they're pretty solid. If you don't plan to replace buttons often, it shouldn't be an issue. on Mar 26th 2019
