    The LayerShift Concave button plunger installs into a Sanwa 24mm or 30mm OBSF style button housing to recreate the retro feel of the early American arcade scene.

    LayerShift, designer of 3D printed utilities such as the Screwbutton Wrench Tool, invites you to recall the feel of pushbuttons from the 80s USA and European arcades.  During that time, many stand-up arcade cabinets were constructed largely of wood, and utilized longstem Suzo Happ or Industrias Lorenzo pushbuttons.  These pushbuttons differed from Japanese button models from Sanwa or Seimitsu in that the button plunger is concave; its surface curves inward, rather than outward. This shape lightly surrounds each finger.

    3D Printed Cap with Smooth Coating

    The nature of 3D printing creates a fine stippling around the cap.  It's quite a unique feeling, but should otherwise not affect gameplay.  Layershift's concave caps undergo a chemical process designed to partly "melt" the 3D printed plastic, offering a glossy and polished presentation that allows your fingers to more effectively glide from the button.

    Compatible With Sanwa OBS Series Pushbuttons

    The Layershift Concave were designed to install in the following Sanwa OBS Series pushbuttons:

    • OBSF Snapbutton
    • OBSN Screwbutton
    • OBSC Translucent Snapbutton
    • OBSJ Metallic Coated Snapbutton

    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. Nice retro look

      I like the old school feel of these buttons. At first I thought they didn't fit, but with a little (very little) persuasion, they snap onto the microswitch inside and work perfect. on Jan 25th 2021
