  • Product Description

    Sanwa's highly anticipated addition to their popular arcade button lineup comes in the form of 30mm translucent buttons! Available in multiple 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 Pushbutton

    If you are not certain about how paper artwork is inserted into the Sanwa OBSC, this quick tutorial may assist. new-window-icon.png

    Silencer is our 1mm-thick foam washer that helps to dampen the loud sounds common with tapping on the button plunger.  It conforms to the internal housing of many Sanwa or Seimitsu-style 30mm pushbuttons.

    Silencer Installation

    installing the Silencer foam pads into a Sanwa or Seimitsu pushbutton is straightforward.  Place the washer - plastic film side down - into the button housing.  Align the small tabs so that they stick out of the holes on each side of the housing.  For Seimitsu PS-15, and Hori Hayabusa low profile pushbuttons, snip the tabs off with scissors and place into the housing.

    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. Good not great

      These are a bit more sensitive than standard sanwa buttons. One of the button tabs broke off already one of the ones I ordered. I guess the plastic is more fragile. I wish these were screw type. Other than that they look fantastic. Got used to them pretty quick. on Mar 30th 2018

    2. Best Push buttons to customize your Fightstick

      These push buttons work great. But the real selling point is that it's easy to put int your own artwork on the buttons to make your fighting stick something original. Also it's easy to add some LED lights to make it really something special on Dec 12th 2017

    3. Nice product, fast delivery.

      Nice product, fast delivery. on Oct 28th 2017

    4. Great for Madcatz TE2

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

    5. Love them

      No complaints from me on Nov 4th 2016

    6. 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

    7. 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

    8. Accuracy guaranteed!

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

    9. 2 weeks in

      Putting the artwork into the button was a piece of cake. Installing it on my Rap4 was just as easy. Feel and work exactly like the stock Kuro buttons that came with the stick initially. on Nov 25th 2015

    10. After 2 weeks of heavy use

      I ordered these with the intention of putting artwork in them to match my stick. The art was easily installed, as were the buttons (I have a TE2). So far, so good. They look great and I've had no problems with breakage. Only 4 stars because I haven't tested them extensively yet. on Sep 29th 2015
