  • 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. amazing buttons

      good buttons. nothing really more to say on Oct 2nd 2019

    2. The Arcade Standard

      My one complain about these buttons is that they hurt when they’re bottomed out. Other than that, they’re pretty good. on Aug 25th 2019

    3. Fantastic

      These buttons are solid, they fit into their spot without any play. I use the Seimitsu PS-14-D switches because I like a little play on the top so I can rest my fingers just barely touching the buttons, instead of the almost instant fire the default switches have. The buttons are extremely consistent and reliable, they return to 0 faster upon lifting your finger than the Hayabusas do.

      With the foam inserts they about as loud as the Hayas but it's a deeper sound. The Hayabusas are shorter throw, but I like these buttons far more.
