  • 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 24 and 30mm.  We'll also expand the key for future models if another size is introduced, and we offer for sale.

    1. Great for Madcatz TE2

      Fit very comfortably. Very easy to insert art into and just pop into your arcade stick. on Feb 24th 2017

    2. Love them

      No complaints from me on Nov 4th 2016

    3. Beautiful but weak

      I love these buttons but for some reason they were way more harder to take out. Its like using a ton of force just to get it out. Now I'm still giving it 4 because its probably just my stick. Also the tabs for the button break easy. Art is easy to put in and looks great. on Oct 6th 2016

    4. Add art to your Sanwa Buttons

      Doing a cool art/light mod? We already know that translucent or semi-translucent buttons are great for light mods, but to do art on your buttons we used to need Seimitsu buttons to accomplish that. Not anymore! Now you can keep using your beloved Sanwa buttons and still put art in the buttons. Sturdy as any Sanwa button, but still able to pop them open and put art in them. I'd recommend these to anyone looking to add custom art to their arcade stick buttons. on Apr 20th 2016

    5. Accuracy guaranteed!

      Amazing. You touch them a lil bit and BOOM... combo city. on Feb 18th 2016
