  • Product Description

    Playing until 2am while allowing your family members a good night's sleep was nearly impossible until now. Sanwa's "silent" pushbutton - the OBSFS - dramatically reduces the sound of your command inputs, allowing you to play confidently while others in your household can relax.

    Foam Disc Padding

    The loud tapping noises that defined Sanwa's original line of joysticks are no longer part of your gaming sessions.  A light foam disc now muffles the plastic points that make contact during a button press.  Sanwa's signature SW-68 microswitch is just as sensitive to your inputs as before; there is no compromise on quality.

    Silence is Golden

    The SANWA OBSFS-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.  

    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. Not 'Silent' but Drastically Quieter

      With a new baby, it's impossible to play in my house at night with conventional Sanwa buttons. These OBSFS buttons are far quieter when pressing than normal OBSF buttons, yet they retain the same responsiveness. It's definitely worth the 50ยข premium, which amounts to about a $4 difference on most sticks.

      Note that these are not 100% silent, and they still make a bit of noise...most noticeably on button release. I dropped a single one of these buttons into a stick to compare it with FA's own foam dampeners, and these are just slightly quieter. The FA foam is still quiet, but it actuates just a little bit louder and in a higher pitch, whereas the OBSFS is low and sounds more hollow.

    2. Quality Upgrade But I Could Be Color Blind

      Update by FA: Sanwa labels the model as OBSF "Dark Blue", however, the color matches as it is in the photo.

      I really enjoy the response and damping sound of these buttons. I was a little surprised with the color though. When I ordered them I was expecting a dark blue as they are labeled. What I got was purple like Transformer's Decepticons purple. Not what I was expecting but the look pretty good none the less.
