  • 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.

    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. Great upgrade

      Beautiful buttons. Some people said they had issues with the clips. Helps a lot if you get the button install tool. Makes removing and installing buttons a breeze. on Sep 20th 2023

    2. Great button

      I'm using this 30mm for my up directional button for my custom hitbox. on May 10th 2023

    3. thank again

      Thank you so much for the pickup. on May 7th 2023

    4. Works Great

      Bought a set of 6 of these to insert some art into and they add tinted look to the art but it worked with my theme. Buttons have great response but they do feel different than a solid plunger so if you want that solid plunger feel you are not going to get it. on Aug 1st 2022

    5. Performs Beautifully

      Incredible button, looks beautiful in just about any case. on Jan 18th 2021

    6. Nice product, fast delivery.

      Nice product, fast delivery. on Oct 28th 2017

    7. Great look!

      The buttons look fantastic, I hadn't known that the plungers were 2 pieces when I bought them. I found out later this is for art over lays, but I had planned on replacing my plungers with solid ones anyways so it's all good! on Jan 25th 2017

    8. Looks good, feels good

      I use 6 of these on my 8 button fightstick, and they look great with white LEDs. The photo is quite accurate to what the color is in person. My only complaint is the 2 clips on the sides are very fragile. You are likely to break one every time you insert/remove the button. This is more of a Sanwa button issue than something inherent to this specific color. Other than that, great product. on Oct 19th 2016

    9. Beautiful but delicate.

      I love the look of these buttons they look great on my fightstick but they are way to delicate while I was inserting them in my fightstick the snaps broke on 3 of them. I am really disappointed by this but the buttons stay snug for the time being so its not the worst case. If replacement are a thing I would really appreciate it, if not its no big deal. on Oct 14th 2016

    10. Excellent Classic Buttons

      I bought these to replace the stock buttons on the Hori Real Arcade Pro 4 Kai and they are fantastic! Very easy to install and provide the classic arcade feel that I grew up using! A must add to any arcade stick due to their high quality and durability. on Aug 12th 2016
