  • 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. The PS-15 uses the Seimitsu PS-14-D Button Micro Switch.

    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. Excellent performance with SW-68 microswitches. Seimitsu should check molds, though...

      The PS-15 is an old pushbutton design and allegedly one of the early short-throw pushbuttons marketed.
      It's a REALLY short pushbutton. I think only the Hori Hayabusa pushbutton is as short!
      As bought, the PS-15 is fitted with PS-14-D microswitches but these are swappable with the Hori Hayabusa microswitches and the Sanwa SW-68 microswitch used on the Sanwa OBSF-series (both 24mm and 30mm) pushbuttons.
      Personally, I think the PS-15 performs better with the SW-68 microswitch and feels a LOT more comfortable with this Sanwa part, too. For a while, the modded pushbutton may feel awkward until it settles in or you get used to the feel of the SW-68 microswitch installed in it. I have SW-68 modded PS-15s (red and light blue) installed in two HRAP Classic bases and they perform well with the Seimitsu LS-32 lever combination.
      I do have a criticism as noted in my headline... I really think something is going on with the molds or Seimitsu is not doing a good job monitoring mold injection. I found imperfections on several of my PS-15 bodies and have to shave some rough "hard flash" areas off the bodies.
      The PS-15 pushbutton does tend to fit tightly into faceplates so don't go removing it all the time. You may break the pushbutton trying to remove it.
      It's difficult to tell when the nibs are removed. I had to remove the nibs before installing the PS-15s into a joystick base that had a plexi cover. The nibs on the PS-15 are extremely narrow. Considering how tightly the PS-15 fits into faceplates, I wonder why Seimitsu bothers including nibs in this pushbutton's mold!       on May 19th 2024
