  • Product Description

    The SANWA OBSF-24 is the smaller cousin to the Sanwa OBSF-30 pushbutton.  Most joystick start, select or turbo options use this button. These buttons are compatible with the MadCatz line of FightSticks, Qanba FightSicks and custom joysticks.  These low-profile buttons are specifically for joysticks that use a metal control panel.

    Sanwa's 24mm 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.

    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.

    8. Gold Standard

      White ones came with my HitBox and I added silencing pads. Got some black ones for modding my TES+. These buttons are very reliable and function the way you'd expect them to. I have absolutely no complaints or problems with these pushbuttons. You cannot go wrong. on Feb 25th 2017

    9. Excellent replacement for the Neo Geo AES stick buttons

      In overall these buttons are the perfect fit for the Neo Geo AES stick buttons which today the microswitches for those buttons are hard to find. on May 31st 2016

    10. Comes As Advertised

      If you have OCD and just want to replace that Start/Options button on your stick to match the rest of your buttons, definitely go for this. However, just a small warning to those trying to replace their HORI Options Button, the Sanwa 24mm button fits just a bit loosely, letting the button rotate around, but you won't notice this unless you intentionally rotate it. on Apr 5th 2016
