GamerFinger products will remain on reserve until further notice. What does that mean?
If you have any questions, please feel free to contact our customer service team by email or click the Help or "?" icon to display a search box and form.
GamerFinger was the first company to introduce a game-changing approach to pushbuttons, utilizing a mechanical keyboard switch to customize both input force and feedback. The unique construction of the GamerFinger HBFS-G3 - a redesigned successor to the G2 - improves on the previous year's implementation to better fit in modern Fightsticks and arcade control panels.
The HBFS-G3 by Gamerfinger incorporates the durability, sensitivity and adjustability of the incredibly popular Cherry MX™ mechanical keyboard microswitch into a unique, quiet 30mm pushbutton. Redesigned for a much smoother install, GamerFinger listened to some feedback regarding their incredibly firm tabs, and the difficulty to remove once inserted into a pushbutton hole. The included plastic ring will keep the pushbutton in place when installed in a wood control panel. The screwbutton ring will accomodate thicknesses up to .5 inches.
The screwbutton ring is also compatible with a metal panel. Unlike the G2 model, the ring screws all the way to the top of the rim. This allows you to screw to a thin metal panel without concern of a loose fit. Additionally, the ring is flush with the button rim, promoting an easier install into metal panel configurations than other screwbuttons.
Should you still need or want to bottom out your button presses, each HBFS is outfitted with a foam pad that dampens the sound, offering up to 20dB less noise than stock Sanwa OBSF buttons.
Sanwa's RG microswitches are known to last longer than the standard SW-68 switches. Thanks to the mechanical key switch, HBFS possesses a much longer lifespan through use of mechanical switches - 50 million operations versus 500,000 - for about the same price as as the RG.
Replacing your buttons with HBFS-G3 pushbuttons is simple as swapping out Sanwa OBSF pushbuttons. No special wires or adapters are needed. Replacing the key switches is also quite easy, requiring little effort to open and pop out the switch.
IMPORTANT NOTE: Non MX switches, such as Gateron or Kailh tend to use thinner metal prongs, and may not always register inputs due to less capacitive contact. It is suggested on forums such as Reddit to use dabs of silver epoxy on the contacts within the GamerFinger's button.

Operating Force, Feel, and Different Key Switches ExplainedThe immediate benefit of incorporating the HBFS pushbutton into your gameplay is the ability to choose your preferred level of operating force, simply by switching out the mechanical key switches. 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 g45g, for example, represents a metric unit of force. Swapping Key Switches to Adjust Operating Force and FeedbackBecause the HBFS uses mechanical key switches, you can purchase other switches that offer a higher operating force, or a different feel. Each are color-coded based on their characteristics:
![]() Cherry MX™ Red
Cherry MX Red is a 45g linear feel key switch. It takes very little effort to press the button down. The feeling is quite unique, very soft yet responsive. These also offer no audible click when pressed down, unless you force it to "bottom out" -- pushing the button all the way down to its plastic contacts.
![]() 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.
![]() Cherry MX™ Black
Cherry MX™ Black "linear feel" is both silent and linear, meaning that from actuation to fully pressing it, it feels the same. These require 60g operating force, so it is likely that you will press all the way down to activate the button command. These are great for those who feel that Sanwa microswitches are too sensitive or tend to activate unwanted commands simply by brushing across the buttons.
![]() Cherry MX™ Brown
Cherry MX™ Brown "soft tactile feel" sends a slight bump as feedback, but no click. This is great for those who want the feedback, but no sound. The feedback tells you when the command was sent to the console or PC. It has a softer feel than cherry MX Blue, but at 55g requires just a bit more force to actuate the switch.
![]() Cherry MX™ Blue
Cherry MX™ Blue "click tactile feel" sends a little bump to your fingers, and has an audible click the moment the button command is sent to the console or PC. The feedback can speed up your execution because you do not have to press the button all the way down to activate the button command. The diagram at right shows how the blue MX switch works. You can see that the switch activates at the halfway point -- the moment the white piece snaps down. 60g means that a bit more force is needed to push down.
Tactile Feedback. Faster Actuation. Silent Operation. Light Touch.The Razer orange stem mechanical key switch sends a little bump to your fingers, but unlike the Razer MX Green Stem 50g Tactile Feedback Mechanical Switch, the operation is quiet - no audible click is provided. At 45g force to actuate, the Razer orange stem mechanical key switch is sensitive enough to satisfy those who desire immediate input and a light touch. Actuation distance is 1.9mm, just under the 2mm present in the Cherry Red MX mechanical switch. This enables a faster actuation time. Tactile Feedback. Faster Actuation."Click tactile feel" sends a little bump to your fingers, and has an audible click the moment the button command is sent to the console or PC. The Razer Green 50g mechanical switch offers this kind of feedback, along with a shorter actuation point than the leading mechanical key microswitch. Actuation distance is 1.9mm, just under the 2mm present in the Cherry Red MX mechanical switch. This enables a faster actuation time. At 50g, the green mechanical switch uses a bit more operating force to press down, which some prefer over feather-sentivity of lighter force microswitches. |
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
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 ConfigurationMost 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.
