  • Product Description

    The SDB-202 is an evolution of the original SDB Series 201 and 201-C pushbutton, utilizing a Silver Cherry MX mechanical keyboard switch for high speed input.

    Cherry MX Silver Switch

    Cherry MX™
    Speed Silver

    Cherry MX™ Silver "linear feel" is an input speed evolution from the red MX. Both silent and linear, the travel distance to actuation is greatly reduced from 2mm to 1.2mm with total travel of just 3.4mm. There is no audible click feedback.

    What does linear feel or tactile feel mean? Linear feel means that the feel is consistent from the moment you press down on the button. Tactile feel provides a bit of feedback upon actuation. Operating Force means how hard you have to push the button and how hard it will push back when depressed.The g in 45g, for example, represents a metric unit of force.

    Now 24mm. Screwbutton Style.

    This SDB-202-MX arcade button now comes in the compact 24mm size, giving HitBox fans an opportunity to experience Samducksa's take on the mechanical switch button. Unlike the 30mm 202-MX, the 24mm variant houses the microswitch in the pushbutton housing rather than a MX to terminal adapter. This does improve its capability to swap out new switches, as it removes the separate and loose pieces that were used in the 30mm version.

    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 cap of the Samducksa SDB-202 houses a clear plastic plunger, which is used to connect to the MX switch.  The Cherry MX switch is securely fastened into the SDB's switch in a similar manner that the 201's Japanese Futaba switch is managed.

    Bright, Vibrant Color Choices. Mix and Match Plunger and Rim

    The solid color buttons are available in a healthy choice of vibrant solid colors, which closely match Sanwa's offerings, ensuring a good opportunity to mix and match peripherals while adhering a traditional Sanwa color scheme.

    An additional feature is the ability to mix and match between the translucent SDB-202C series and solid color SDB-202, providing many combinations for your own customization.

    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.

    Tech Corner: Swapping Mechanical Switches in the Samducksa 202 Pushbutton

    Inspired by GamerFinger, Korean arcade parts manufacturer Samducksa (Crown) introduced the 202 and 202-C mechanical pushbutton in 2019. The 202 features a Cherry MX-Silver mechanical switch for ultra-quick inputs. However, should you desire another MX-style mechanical switch, it is possible to install one by following the instructions in this episode of Tech Corner by our technical support contact Joe Howell (aka NGN | No Good Citizen).
