Description 5 Reviews 24 vs 30mm The SANWA OBSF series is considered the standard in high-quality Japanese arcade and commercial joystick pushbuttons. These buttons are compatible with the MadCatz line of FightSticks, Qanba FightSicks and Hori Fightsticks. These buttons are specifically for custom joysticks that use a metal control panel. Sanwa's 30mm button snap right into most configurations, and offer the best reaction time, smoothest and quietest of any button. The buttons are available in a variety of colors for great customization. Additionally, you can swap out the button plungers for even more customization. Bundle with Silencer 30mm Foam Washers 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.

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. 5 Reviews Hide Reviews Show Reviews WRITE A REVIEW Write a Review Close × Sanwa Denshi Sanwa OBSF 30mm Pushbuttons Vermillion Rating Required Select Rating 1 star (worst) 2 stars 3 stars (average) 4 stars 5 stars (best) Name Required Email Required Review Subject Required Comments Required Closer to red than pictured Sanwa Vermillion buttons are perfect for matching with the default red that Seimitsu uses or getting closer to the more vibrant red used in classic arcade cabinets for balltops, etc. I use vermillion buttons for my Neo Geo layouts. Sanwa's default 'red' is too dark. Ben on Dec 18th 2020 Buttons work fine but Buttons work like you'd expect sanwas to work. However if you plan to install these in a rap n like i did, you should know that i had to use a good amount of force to actually fit them in the button holes. There are a few small indents on the side of the button that actually collide with edge of the button hole. I don't know if that was just this specific color or if it's on all obsf's though.

In person, these buttons are often difficult to distinguish from plain orange. So, if you're thinking about a Yellow, Orange, Vermillion, Red setup, know that it'll really look like Yellow, Orange, Slightly darker Orange, and Dark red. Basically, Sanwa should call this "Orange" and their current orange should be called "Light Orange," if that makes sense... Frank P. on Sep 25th 2015 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 Another 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 a
Installation Quick Reference
Mounting: Snap-in buttons push into a 30mm hole from the top of the panel. Screw-in buttons thread from below and secure with a nut. Use 2-3mm acrylic, wood, or metal panel.
Wiring: Connect the microswitch terminals to your encoder or PCB. Common ground shared across all buttons. Quick-disconnect (0.110") terminals are standard on Japanese buttons.
