  • 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.

    1. Don’t Properly Fit BNB Gen 2 Sidepanels

      From FA:

      Please note that in the BNB listing, we specifically recommend 24mm screwbuttons instead of snapbuttons. This review does not speak to the quality of the buttons in question, but rather a fitment issue that was warned in the case listing.


      Annoyed. Ordered a BNB Gen 2 case and didn’t notice that there are two sets of 24mm button holes. Accounted for all buttons and items in initial order. Had 3 leftover 8 y/o old Sanwa 24mm buttons from a previous project that fit perfectly in the BNB plexi. Assembled the stick and realized there are 3 empty holes. Ordered 6 new blue buttons to fill all holes and look better than the white ones, the wire harness for the PS, L3, R3 buttons that I’ll likely never use, and the new buttons are ever so slightly different where the plastic clips don’t activate and these just fall in any out of the BNB case. While the ad says these are designed for metal cases, I feel it should also say they don’t fit BNB plexi as that appears to be the main case type sold on the site. So I can either glue em, or grind the plexi, or buy separate buttonless side panels for $27 plus likely the same in shipping to Canada. Not ideal. First fail from this site, and my stick building in 6 different sticks.

    2. Kind of dissapointed

      Color is slightly lighter than the 30mm version I have. Also, it is a tad smaller(diameter) than it should be as it does not fit perfectly in place. I can spin and wiggle it around a bit. Makes me a bit uneasy, but good thing it's only for the start button. on Jan 24th 2017

    3. Just what I needed

      Hard to find these little 24mm buttons in the U.S, needed one to replace my old options button for a panel I'm modifying, and it works great. Hooks right in, no issues, fits the cutout exactly. Will be returning for more! on Sep 18th 2015
