  • 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. As expected from sanwa push buttons

      Bought a 24mm start button, work as intended. Definitely better feel than the default button from Mayflash F500. on Jul 8th 2023

    2. A classic

      Nice and responsive, there’s a reason Sanwa parts are used in top tier sticks. I also like that they can take a beating during intense play sessions and make just the right amount of click when slapped. Don’t think I’ll ever switch. on Jul 9th 2022

    3. a necessity for arcade standard

      Definitely useful for arcade and fightstick use on Dec 6th 2019

    4. They dont fit my arcade stick ;-;

      Update from FA: It appears that you purchased 24mm option buttons instead of 30mm action buttons. In each product listing, we include a tab called "24mm vs 30mm", which explains which buttons are used for the control panel.

      I didnt get to try them cause they're too small       on Mar 30th 2018

    5. Great buttons, work as expected

      These came in great condition, and work perfectly. There's not much else that I can say about them, they're buttons and they work like buttons should. Very responsive, and they have a nice clicky feel. Would recommend. on Aug 9th 2017

    6. Feels like a legit part that will last a long time

      I picked up a lot of 24mm buttons for a custom hitbox i was making and for both the dpad, and the P and K rows to the start and select, this is a great feeling button and I couldnt have made a better choice. they are easy to tap with any finger on either hand and are responsive and give you a nice solid clack if youre a heavier tapper like I am. on Aug 4th 2015
