Samducksa, more commonly known as Crown in Western territories, has a long history of respectable South Korean joystick levers and pushbuttons specific to that region's arcades. Over time, Samducksa has increasingly embraced the Fighting game market, which is currently dominated by Japanese import peripherals. Their latest efforts in the 303, 307 and 309 series of joysticks factored the Japanese style Fightstick in its design, enabling installation into the more-common hardware.
The SDB-201C aims to offer that same compatibility to the pushbutton, resulting in a high-quality pushbutton that offers a solid, satisfying feel when depressed.
Translucent and LED Ready
The 201-C features a translucent housing and plunger design similar to the Seimitsu PS-14-K and KN series of pushbuttons. Below the buttons are two holes that allow for installation of simple LED lighting - something that is not present on any of Sanwa or Seimisu's offerings. Much like Sanwa's OBSC and Seimitsu's PS-14-k/KN, the button cap is removable, allowing you to insert Fightstick button artwork into them. This is great for customization.
This SDB-201 button is a 30mm screw-in arcade button, complete with a screw ring. The slim screw ring is a great design: it's only as thick as the rim - enough to ensure installs in tight spaces are not hindered by the ring itself. The plunger of the Samducksa SDB-201 button is slightly higher than the button rim; offering a forgiving amount of travel for those who press harder. Button tension is that of Seimitsu, offering just a bit more tension than the feather-light Sanwa. The SDB-201 feels very durable, able to withstand a beating.
Japanese Futaba Microswitch Rated Five Million Presses
Inside each SDB-201 button features a Japanese Futaba microswitch with .110 terminal. Futaba has a high durability rating that compares to the venerable Sanwa OBS-RG series microswitch - the OMRON B2R-G1. Here is a comparison to other microswitches by Sanwa and Seimitsu
- Futaba: 5 million times
- Seimitsu MM9-4 or MM9-3: 2 million times
- Sanwa SW-68: 1 million times
Bright, Vibrant Color Choices. Mix and Match Plunger and Rim
Samducksa color choices for SDB-201C are hardly an accident: The translucent buttons are available in a healthy choice of vibrant colors including blue, clear, green, orange, pink, purple, red, smoke and yellow. These colors closely match Sanwa and Seimitsu offerings, ensuring a good opportunity to mix and match peripherals. That said, Crown also developed a more cohesive color match for yellow and green, among other translucent colors that don't seem to represent as well by Sanwa or Seimitsu.
An additional feature is the ability to mix and match between the translucent SDB-201C series and solid color SDB-201, providing dozens of combinations for your own customization.
Overall, Samducksa's SDB-201 and translucent 201C pushbutton provide solid alternatives to Sanwa and Seimitsu's offerings, and a staple solution for fans of K-Sticks.
|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
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.
