  • 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 buttons

      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. The Standard for a Reason

      +: Easy to install, very sensitive, wide variety of colors. FocusAttack is excellent in shipping immediately and packages are well-protected.

      -: Well-known issue is that the tabs which secure the buttons are notoriously brittle and snap easily. Be very careful when uninstalling/installing.

    3. Looks and feels great

      I got the red, yellow, green, blue and 4 smoked push buttons. I like how sensitive they are, and they are not loud and clanky which is something I like. on Oct 13th 2020

    4. Looks great, a bit sensitive

      Love the look of these buttons, they really pop and I love my buttons to pop. They are a bit sensitive and will activate with very little pressure, which can be a bit of a issue in some cases but I don't really have that much of a problem with it. on Jan 31st 2020

    5. Sanwa buttons = major Arcade1up upgrade

      I bought these buttons for my Arcade1up Asteroids machine. The switches in the stock buttons were to slow to engage and I couldn’t fire consistently. These Sanwa buttons fixed my issues and feel nice. I immediately ordered more. Focus Attack promptly fills your order and provides a tracking number. on Nov 4th 2019
