  • Product Description

    The Seimitsu PS-14-KN arcade pushbutton is only second in popularity to the SANWA series.  Available in several translucent colors, artwork can also be inserted under the cap of the plunger. and are sought after for their increased customization ability with joystick graphics and LED mods.  Seimitsu buttons offer the same high-quality and responsiveness as a Sanwa, but a slightly different feel and sound.

    Each comes with a screw nut, making it an excellent choice for both metal and wood joysticks.  The buttons are compatible with MadCatz FightSticks, Qanba and Hori joysticks. The PS-14 KN uses the Seimitsu PS-14-G Button Micro Switch.

    Black Screw Ring

    The latest iteration of the Seimitsu screwbutton models now possess a black screw ring that is taller, more compact and easier to screw on. This helps the button navigate tighter spaces of some layouts. Additionally, the screw ring design more easily displays the proper orientation to screw in via small bumps at the top, which also help to grip the ring to a metal or wooden chassis.

    Bundle with MM9-4 High Tension Button Spring and Save

    By default, Seimitsu PS-14-G microswitch requires 1.0N or 0.2 LBF (pounds force) to each button. 

    The MM9-4-25N adds an extra .08 LBF (pounds force), for a total of 0.28 LBF.  The result is a light, but firm button input requirement that accelerates its the button cap's return to neutral. 

    The MM9-4-50N adds an extra .16 LBF (pounds force), for a total of 0.34 LBF, resulting in a much firmer button input requirement that quickly pushes the button cap's to neutral position, ready for the next press.

    This is desirable to some who appreciate using more deliberate input force and a bit less sensitivity than Sanwa's SW-68 offers. Now, you can save 25 cents off the regular price of the MM9-4 series spring when you choose one of the high tension springs from the options list.

    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. Poor quality, not what I was expecting.

      First of all, the picture of these buttons does not accurately represent the color overall. Also, there is white plastic underneath the translucent purple plunger, giving it a more lavender look. The main problem, though, is that these buttons can stick. I don't hit the buttons hard, but I still noticed that the plunger can catch under the rim and stick within an hour of installing these buttons. I have some almost 10 year old clear PS-14s that don't have this issue so maybe it's just the batch or the way they are produced now. That said, they have yet to miss an input but I can't recommend them. Find an alternative. on Nov 5th 2018

    2. As pictured.

      works fine, and looks pretty. on Jul 10th 2018

    3. Not what i thought but still cool

      The picture above made me think it would have a translucent look. Though the buttons are glossier than my other buttons, they are mostly solid in color. The rim of the button is dark purple and the actual button is a light purple. However they still look nice and function perfectly on Jul 9th 2018

    4. Beautiful

      These buttons match the Clear people Crown lever perfectly. First time using screw in buttons but I think I'm sold. on Jan 23rd 2018

    5. deep in the purp

      the color in the picture isn't accurate, the color of the buttons IRL is less blue, more traditional purple. i like it though. on Apr 5th 2016

    6. The best buttons for DIY fightsticks!

      In my opinion, Semitsu screw buttons are the best for the 8 main buttons. on Mar 22nd 2016

    7. Love it

      It has been a while since I've been to the arcades so I forgot how Sanwa and Seimitsu buttons felt like. After some research, I decided to go with the more resistant Seimitsus. I wasn't disappointed. These are some really nice buttons that feel great. Much better than the Kuro buttons my RAP4Kai came with. One advice for other RAP4Kai users: You will need a snapbutton for the top rightmost button for this particular arcade stick because there is too little space under the panel for the clear screw thing to fit. on Aug 12th 2015
