  • Product Description

    Get the best of both worlds, and compact! These Sanwa OBSC-24mm buttons a fashioned with clear rim and 9 vibrant colors that match all existing Sanwa balltops. These are fantastic for those who want to add a unique color-coordinated appearance, or limit button LEDs to just the rim.  The 24mm buttons are also great for HitBox™ setups and the start or turbo buttons on the MadCatz™ TE joystick.

    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. Works great, fits in Mad Catz TE2+

      Wanted to change my push button on my TE2+ Ryu arcade stick. Easy to change and fits good snug in my stick. That great Sanwa feel you're looking for. on Mar 30th 2019

    2. great product!

      great product! great responsiveness, as expected of Sanwa products! on Jul 12th 2017

    3. Excellent quality and they arrived in the expected delivery date (Italy)

      I live in Mirandola.
      Shipped from FOLCROFT, PA within 10 days the order arrived in excellent condition
      I ordered 50 for my exam project,
      sensitive to the touch
      and beautiful if re-illuminated with LEDs (blue or red).
      Disadvantage that they were shipped in a simple cardboard box without any soft material around them to avoid cracks during transit.
      Luck that to me they have arrived intact

    5. Sanwa OBSC 24mm Pushbutton.

      There isn't a whole lot that I can say about these buttons, they truly speak for themselves. Huge up's to Focus Attack on the crazy fast shipping though. I live in Delaware so I know I'm not far away but standard shipping at my door in two days max is great. Thanks for keeping what I need in stock, you make the struggle easier. on Aug 21st 2015
