  • 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. They are pretty quiet.

      These buttons work great if you have people who want to sleep and don’t want to hear your buttons clacking in the middle of the night. They had a small learning curve for me because it’s hard to tell if your pressing them at first and they are very sensitive. But after figuring it out I have no issues and I don’t have to worry about making a bunch of noise hitting buttons in the middle of the night while my family is still asleep. on Mar 11th 2020

    2. Just like the normal Sanwa 30mm button... except near SILENT

      I bought a set of these buttons to replace the stock buttons included on the Mayflash F500 and I couldn't be happier.

      The buttons react EXACTLY like the standard Sanwa 30mm buttons, except there is very little click. There is still a slight activation sound but almost imperceptible. You could easily use this in the living room while others are sleeping in their bedrooms.

      I have compared these to the sound made from the Mad Catz TE2 Sanwa buttons and silent is darn near accurate. I also compared button press force side by side and I can't feel a difference. It is possible that pros will feel that difference. I am definitely not a pro.

      Highly recommended.

    3. Pushbutton delight

      Love these buttons, silent to the touch.. thank you focus attack for getting them to me promptly and in prestine condition. on Jun 13th 2018

    4. Works great

      Its pretty quiet, and works great on Apr 16th 2018

    5. A Nice Upgrade

      Installation on my T.E.2 was simple (search for You Tube videos for helpful tips if it's your first time replacing buttons). In my case, the tabs on the original buttons all broke when I removed them, rendering them useless. Something to be aware of for those thinking of making a swap.

      The silent buttons aren't completely silent, of course, but they do offer a noticeable reduction in tapping noise, and more of a 'padded' feel when striking the buttons. Ultimately, they've been a nice upgrade that I'm very happy with.

    7. Yes indeed!

      I love these so much. They sound almost like computer keyboard keys, only more quiet. Comfy to. Took about two hours to get used to the fact that they don't make noise. Cause they REALLY don't! on Sep 4th 2015
