  • Product Description

    The SANWA OBSF-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. Feather touch, better than expected

      I used these Sanwa 30mm buttons in a Mayflash MF002 v2 upgrade project. The default buttons weren't bad...until I replaced them, and I was really surprised at the difference. Feather touch, great response -- they just feel amazing. Very much worth the upgrade for a name brand. on May 5th 2020

    2. Love this color Sanwa button!

      These buttons (and matching light blue balltop) fit perfectly in my RAP N (Soul Caliber VI edition). I like that they have a smooth and flat feel vs the rougher feel of the Hori buttons. Arrived after just three days after ordering and were well packaged. Will definitely continuing ordering from Focus Attack to finish customizing my fightstick. on Dec 9th 2019

    4. Great Buttons

      Sanwa buttons, always a solid choice. on Sep 17th 2017

    5. Amazing button quality

      So I get this to set a layout on my fight stick for the color codes used on Street Fighter, so this is for my light attack.

      All buttons beside the lower one are screw buttons because my TES+ don't have room for the last screew button so this performs great, just that is a little bit harder to take in or out.

    6. Perfect

      Color matches photo as shown. Easy to install, solid construction.

      Noisy as expected. Good quality switches and contacts.
