  • 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. Good But Just Not For Me

      Buttons were easy to install and ready to go out of the box, as is usually the case for Sanwa.

      However, it did feel as though the silent buttons weren't as responsive. That could be a mental thing, but performing confirms with light attacks felt off. Almost as though they were harder to press, or my brain was relying on the tactile sound of the regular sanwas. I did have a few that were sticking, so I just decided to open up the button and remove the silencer.

      If you're on the fence because you've never tried it, go for it. Worst case scenario is you hate it, which you can then fix by removing the silencer pads and you have regular buttons again.

    2. I really like these buttons.

      Sound wise really noticeable improvement from rap4s original buttons. on Feb 13th 2018

    3. Not silent, but quieter

      This button certainly isn't silent in the true sense of the word but it is quieter than the default Qanba Q1 buttons. I haven't had this button long enough to give it a detailed review or anything like that but so far it seems like a good product.

      I bought one as a test button to see how it compares to the others in both feel and noise. If the button holds up well then I'll replace the other buttons with these.

    4. Silence is golden

      I love how much quieter these are than the Qanba Carbon Stock Buttons are. The colours match the faux carbon fibre look as well. I wouldn't say they are more responsive than the stock ones, but sure feel a lot nicer. I didn't give it five stars because the surface of one of them is scratched, not enough to feel it though. Likely a shipping issue, rubbing against the contact of another button. Maybe those contacts should have little plastic covers for shipping. on Dec 11th 2017

    5. They're great

      They're great, they're significantly more quiet than than the standard 30 mm sanwa push buttons. They are very responsive. And the color matches my hori hrap4 perfectly. on Mar 4th 2016

    6. Work fine but looked used

      The surfaces of all 8 buttons were scratched and looked either used extensively or just plain abused by focus attack. They work fine otherwise.

      ** From FA: We do not offer used buttons, however they cannot always arrive to us pristine. Please see this FAQ regarding button condition: **
