  • 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. Great Buttons!

      These buttons are great to make full use of the custom art for your fighstick. Just be careful when installing them because the tabs are very fragile. But the buttons work and look great. on Apr 29th 2019

    2. Good, but Fragile

      They feel as other Sanwa OBSFs do, with the added bonus of a clear button housing that blends with a lot of stick designs and artwork caps that lets you insert your own artwork. However, I find that they are quite consistently brittle; when I removed some from my stick, 4 of them had broken tabs, and a couple more had tabs that nearly snapped. Aside from this, they're pretty solid. If you don't plan to replace buttons often, it shouldn't be an issue. on Mar 26th 2019

    3. Good stuff so far

      Buttons came all good except for the packaging which was ripped but might have been mail carriers fault. I will definitely be making more purchases here in the future. on Feb 19th 2019

    4. Clearly, good buttons

      They arrived on time, I ordered 8 and all of them where undamaged. So far they have held up to me pounding my fight stick. on Jul 27th 2018

    5. Perfect

      Excellent quality, very comfortable. on Jun 13th 2018
