  • 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. A classic for a reason

      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

    2. Great for Neo Geo ASP

      Got this to replace the stock buttons on my Neo Geo Arcade Stick Pro. The Sanwa buttons look better and feel better. They're a breeze to install, no soldering needed. on Sep 29th 2020

    3. a necessity for arcade standard

      Optimal for arcade standard gaming on Dec 6th 2019

    4. Works with arcade 1 up control panels

      These buttons will fit arcade 1 up control panels with some force. on Dec 5th 2019

    5. Excellent sanwa buttons

      Coloring is snow white exactly as expected. Plus they have that nice classic sanwa feel. on Aug 15th 2018

    6. Great

      Great Buttons! on Jun 14th 2018

    7. The buttons make squeaky noises but it does not bother me too much

      I like how the buttons sound and feel responsive when I press them. I made the right choice by replacing my Mayflash F300 blue buttons for these awesome Sanwa buttons hahahaha!!! on May 4th 2018

    8. Great Buttons

      The current standard in joystick buttons. Responsive and durable, and it was easy to replace the buttons on my joystick with these. on Sep 17th 2017

    9. Great!

      Really stepped my game up buying sanwa buttons. Feels amazing! Very responsive and improved my reads and combo's in USFIV and SFV. on Sep 6th 2017

    10. Feel the difference

      My fight stick is the Hori Rap 4. Had a slight issue with installation. All the buttons had 4 ridges that were raised. It wouldn't enter in flush. I took a pocket knife and shaved off the excess raised plastic ridges and they fit in great and work fine. I also would recommend the foam silencers, those are awesome on Jun 9th 2017
