  • Product Description

    Sanwa latest and highly anticipated addtion to their hugely popular arcade button lineup comes in the form of 30mm translucent buttons! Available in 6 colors, these still feature the feather-sensitive, competition-ready SW-68 microswitch and look fantastic in a 6 or 8 button setup.

    Adding Artwork to Sanwa OBSC-30

    While not an exact tutorial for Sanwa OBSC buttons, this helpful tutorial for Seimitsu PS-14 G buttons will clarify some of the steps needed to install custom artwork into a Sanwa clear plunger.  (Tip suggested by SRK's Maximiliano)

    Artwork Diameter

    Actual diameter for artwork is 20.7mm (thanks to jPenguin of 801 Mods)

    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. Functional Buttons

      Bought a Hori RAP4 kai and wanted to swap out the stock Hayabusa buttons for Sanwa. These caught my eye and figured why not try them out, so far they are completely functional with no signs of poor performance with a noticeable tap difference from the Hayabusa.

      Will definitely be purchasing more to completely replace all stock buttons.

    2. Break all the time

      So once these things are in place I suppose they work well. Problem is if I ever change the art the tiny little side clips (that hold it in place) break causing the button to half way pop out when pressed. The button still works it just makes pulling off combos not very fluid.

      I've tried buying these multiple times and they ALWAYS seem to break easily. I don't understand the difference, I use a TE2 Killer Instinct stick, and the buttons that came with the stick seem just fine.

      In fact, I have had to replace multiple of these as well as the translucent yellow with the blue and red buttons that came with the stick just to make the stick feel more fluid.

      Really wish I could give these a good review as I love the color they produce but the way in which they break so easily is so annoying.

      Update by FA: Indeed the tabs must be handled with care when removing. This is the case with all OBSC buttons, versus OBSF.
