Unknown on Jul 12th 2019 I wanted white button they were out blues clues is the way to go You don't know how good it looks on my baby arcade stick in till you see José Alberto Maldonado on Mar 6th 2017 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 also expand the key for future models if another size is introduced, and we offer for sale.
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.
