  • Product Description

    The SANWA OBSJ-30 continues as 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 low-profile 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.  You can also buy multiple buttons and swap out the rim 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.

    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. 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.

    2. Look fantastic!

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

    3. 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.

    4. 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

    5. Everything you could want from the product.

      Its very simple. Do you want a solid quality metallic gold 30mm Sanwa Button? Yes, get this. No? Why are you reading this. Only disclaimer, it metallic gold painted, in case there is someone, though unlikely, who gets it confused. on Feb 28th 2018

    6. Its so shiny

      A big fan of the gold and a good replacement for the balltop of my joystick. on Oct 31st 2017

    7. Gold!!!

      Beautiful coloring, about as close to gold as you can get! The finish is amazing and it is damage resistant. Top notch!! on Jun 28th 2017

    8. The look great!

      They look good! And the buttons works like a charm. on Jan 27th 2017
