    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.

    2. Outstanding

      I love the feel of the buttons, and the way they look on the stick on Apr 1st 2021

    3. Really can feel the feedback

      Got these on a recommendation from Marlinpie and am very satisfied. These buttons feel more like the classic arcade buttons I remember; with a bit more push back that really lets you know you've smacked that button. on Apr 27th 2020

    4. Tab on these buttons break quite easily

      I had to reinstall these buttons couple times whenever I wanted to change artwork on my Panthera. On my 3rd removal 7 out of my 8 buttons had its tab broken

      These items are quite fragile, so either remove sparingly or be very cautious when removing them.

    5. Classic buttons

      Easy to install, plastic isnt too fragile when I had to remove one. It's nice to hit new buttons again on Jul 17th 2019

    6. Top notch buttons

      A great upgrade to my stock Hori buttons on my rap 4. Not a slight on Hori but they are a little to loud. Sanwa’s feel more like the arcade buttons we all grew up playing in. on Aug 17th 2018
