  • Product Description

    The SANWA OBSF series is considered the standard in high-quality Japanese arcade and commercial joystick pushbuttons. These buttons are compatible with the MadCatz line of FightSticks, Qanba FightSicks and Hori Fightsticks.  These buttons are specifically for custom joysticks that use a metal control panel.

    Sanwa's 30mm button snap right into most configurations, and offer the best reaction time, smoothest and quietest of any button.  The buttons are available in a variety of colors for great customization. Additionally, you can swap out the button plungers for even more customization.

    All New Metallic Color - Evaporative Paint will not Peel

    Sanwa's popular pushbuttons and balltop accessories now come in a stunning metallic gold and silver evaporative paint, which is designed to eliminate the peeling or scratching found in more common metal plated plastics. More metallic colors may arrive over time.

    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 feel, but quite fragile

      I bought a pack of 6 buttons, everything really good at first but one of the buttons started to not respond, in one of my troubleshoots i broke the things that were attach the the button to the arcade llayout even using the most care as possible. Never happened to any button before.

      Maybe a faulty button did that, the other 5 buttons are very responsive, feels really good and it gives the premium feel to the arcade

    2. Exactly what i needed

      The buttons looked and felt great! slightly quieter than the mayflash f500 default buttons! Will buy again on Nov 17th 2022

    3. They look amazing!

      I haven't installed mine yet, I was kinda hyped for them to come so I could see if they looked as good as they do on the site and they do! I can't speak on the issue I saw in the reviews with the tabs but as another user said I cant see theses coming out. I can't wait to be able to order a print and cut so I can put everything together.

      *If everything installs fine I'm adding the last star

    4. I love GOLD!!!

      As other reviews have mentioned the release tabs are on the flimsy side so whatever you install them in don't plan on taking them out. Not that you would want to these buttons look damn fine.

      I had a small problem with one of the buttons getting scraped up while shipping. Focus attack had a replacement button cap sent out in less than a week.

    5. I need to have more

      Makes you want to guy the buttons for all my sticks on Aug 7th 2020

    6. HORI Fighting Edge

      I ABSOLUTELY LOVE THESE! Was waiting for a long time for them to be available, I'm really glad I waited on Jun 15th 2020

    7. fragile release tabs, otherwise good

      These seem to be slightly less durable than common Sanwa OBSF buttons. I purchased a set of 8 (6 gold, 2 silver) back in October and was very satisfied. However, I have already broken a release tab on two of these buttons. I had never broken a release tab on a Sanwa button before this, having repeatedly and extensively rearranged the OBSF buttons on one of my sticks for years.

      Otherwise, these are good buttons. Just be careful with them.

    8. Look fantastic!

      Goes great with my golden balltop and Etokki Omni. Sanwa buttons are always the best. on Mar 25th 2019

    9. It's a Sanwa button. It's also gold.

      If you've ever used Sanwa buttons before, this is functionally identical. No disappointments.
      The gold paint is very, very shiny. You can see your reflection in it.
      It also perfectly matches the color of the gold LB-35 balltop, also sold on this site, so if you want to do a full gold theme, rest assured that they match.
      The color is a little washed out, but it's still yellow enough that, under light, people won't mistake it for a different color.

    10. Loving them

      I got a complement from the biggest fighting game channel for the big band redesign I did with the buttons, on Aug 7th 2018
