Qanba Gravity KS Mechanical 30mm Silent Pushbutton Set - Quiet, Smooth

In this review the Qanba Gravity KS 30mm silent pushbutton set is evaluated for gamers and DIY controller builders who want a quieter, more responsive button option. The boxed set of eight original Qanba snap-in buttons delivers a noticeably quieter operation thanks to a silicone inner cover and a mechanical linear shaft that reduces click noise while preserving a crisp feel. If you need replacement parts that fit most joysticks or want to build a custom controller, these buttons are built for longevity and usability.

Key Features

• Original Qanba quality: These are high quality original buttons that match the fit and finish expected for arcade-style builds and replacements.
• Mechanical linear shaft: The linear switch provides smooth actuation and consistent feel across rapid inputs, useful for fast-paced play.
• Silent operation: A silicone inner cover makes presses quieter and reduces audible feedback without sacrificing responsiveness.
• Long lifetime: Rated for 70,000,000 actuations, the buttons are built to withstand heavy use over time.
• Snap-in mount: Snap-in design makes it easy to replace existing parts or install in a variety of joystick panels without soldering.
• Precise travel and force: With 0.8 mm pre travel, 2.8 mm total travel and 45 cN operating force, the buttons strike a balance between sensitivity and deliberate input.

Who It's For

These buttons are aimed at arcade enthusiasts, fighting game players and DIY controller builders who value a quieter button with a smooth, linear feel and robust longevity. Because they are original Qanba parts with a snap-in mount, they are a convenient upgrade or replacement for many joystick cabinets and custom fight sticks.

Those who need ultra-tactile feedback or prefer very high clickiness may want to look elsewhere, since these focus on silence and linear response rather than a pronounced tactile bump or audible click. Also, anyone with an unusual panel thickness or nonstandard mounts should confirm compatibility before buying.
