  • Product Description

    The Seimitsu PS-15 is a low profile, solid color 30mm pushbutton designed to snap into a thin (1.3mm or .051") metal panel. At just 12mm high without microswitch, the PS-15 is ideal for thinner joystick cases where vertical space is tight.  Unlike the PS-14-G snapbutton, the PS-15 has a convex plunger. This pushbutton is available in 7 colors, along with with a black rim/color plunger variation in 6 colors. The PS-15 uses the Seimitsu PS-14-D Button Micro Switch. Please see our product photo gallery for full specs.  

    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. Very nice button; conveniently compatible with Sanwa SW-68 microswitch as well!

      I've got this exact color button installed on a limited edition joystick.
      I didn't like the original PS-14-G buttons that joystick came with but I still wanted to "keep it" in the Seimitsu family so I bought a set of PS-15 buttons in the same colors of the PS-14-G's I sold to another SRK member.
      I haven't regretted it. The PS-15 is already more like the Sanwa buttons because it has convex (bulging out) plunger instead of a flat plunger like the PS-14-G. The PS-15 also has the advantage in that that like any Seimitsu pushbutton which uses the 24mm-style microswitch (PS-14-D switch) it can also use the Sanwa SW-68 microswitch. SW-68 and PS-14-D's are interchangeable. The microswitches are very different feeling but they are swappable and can be used to replace the other in pushbuttons were they switches have become worn. I chose to install SW-68's in my PS-15's and have a hybrid pushbutton in that Limited Edition Seimitsu joystick (with stock LS-32-01 lever) that I have.
      They're nice-looking buttons. Probably my second-favorite Seimitsu pushbuttons after the much-missed, limited edition Pearls which were absolutely the closest Seimitsu pushbutton in feel to the Sanwa OBSF-30. And Pearls feel more Sanwa-like even with the stock PS-14-D microswitches in them!
      Ya hear me, Seimitsu? Bring back the Pearl pushbuttons!!! You FINALLY got a shaftcover for the LS-32 line, it's time to bring back your softest feeling pushbutton!
