When building or upgrading a mechanical keyboard, the choice of linear switches can define your entire typing experience. For budget-conscious enthusiasts, two popular contenders stand out: the Gateron Jupiter Yellow and the Gateron Milky Yellow. Both offer smooth, linear action at an affordable price, but they cater to slightly different preferences in feel and sound. In this showdown, we’ll break down their differences in depth—covering smoothness, sound profile, actuation force, and real-world typing performance—so you can decide which switch belongs in your next keyboard build.

Overview of Gateron Jupiter Yellow vs Gateron Milky Yellow

Gateron has long been a trusted name in the switch market, known for offering reliable, budget-friendly options. The Jupiter Yellow and Milky Yellow are both linear switches, meaning they have a smooth, uninterrupted keystroke without a tactile bump or audible click. They share a similar price point, typically under $0.30 per switch, making them excellent choices for those looking to build a custom keyboard without breaking the bank. However, their design philosophies differ: the Jupiter Yellow uses a modern opaque housing with a focus on smoothness and durability, while the Milky Yellow features a classic translucent housing that has become a favorite among enthusiasts for its deeper, fuller sound.

Key Specifications at a Glance

Specification	Gateron Jupiter Yellow	Gateron Milky Yellow
Type	Linear	Linear
Actuation Force	50g	50g
Total Travel	4.0 mm	4.0 mm
Pre-Travel	2.0 mm	2.0 mm
Housing Material	Opaque nylon/polycarbonate blend	Translucent nylon/polycarbonate
Stem	POM	POM
Factory Lubrication	Light	None (or very minimal)
Price (approx.)	$0.25–$0.30 per switch	$0.20–$0.25 per switch

Both switches feature a standard 50g actuation force and 4mm total travel, placing them in the medium-weight linear category. This makes them comfortable for extended typing sessions, whether you’re writing code, drafting emails, or working on creative projects. The main differences lie in the housing material and factory lubrication, which significantly affect sound and feel.

Sound Profile: Jupiter Yellow vs Milky Yellow

For many typists, the sound of a switch is just as important as its feel. The Gateron Jupiter Yellow produces a slightly higher-pitched, clacky sound due to its opaque, stiffer housing. It’s clean and precise, but some users find it a bit bright for long typing sessions. In contrast, the Gateron Milky Yellow is famous for its deeper, creamier sound—often described as a “thocky” tone, especially when paired with a polycarbonate or aluminum plate. The translucent housing of the Milky Yellow dampens higher frequencies, resulting in a warmer, more pleasing acoustic profile that many enthusiasts seek.

Sound Comparison on Different Plates

To give you a better idea, here’s how these switches sound on common keyboard plates:

• Aluminum Plate: Jupiter Yellow yields a crisp, metallic clack; Milky Yellow produces a softer, deeper thock.
• Polycarbonate Plate: Jupiter Yellow becomes slightly muted but still bright; Milky Yellow reaches its peak “thocky” potential.
• Brass Plate: Jupiter Yellow sounds sharp and energetic; Milky Yellow remains warm but with added resonance.

If sound is a priority, the Milky Yellow is the clear winner for those who prefer a deeper, more satisfying typing noise. However, if you like a brighter, more responsive sound, the Jupiter Yellow may be your preference.

Typing Feel and Smoothness

Both switches are exceptionally smooth for their price, thanks to the POM stem material. However, the Jupiter Yellow has a slight edge out of the box due to light factory lubrication. The lube reduces friction and creates a buttery-smooth feel right away, with very little scratchiness. The Milky Yellow, on the other hand, arrives dry or with minimal lubrication. This means it may feel slightly scratchy until you apply your own lube—but once lubed, it can rival or surpass the Jupiter Yellow in smoothness.

For typists who prefer a “plug-and-play” experience, the Jupiter Yellow is more convenient. Enthusiasts who enjoy hand-lubing their switches will likely lean toward the Milky Yellow, as it offers more room for customization and cost savings.

Real-World Typing Performance

When typing long documents or coding for hours, both switches perform admirably. The 50g actuation force strikes a good balance between being light enough for speed and heavy enough to prevent accidental presses. The Jupiter Yellow’s slightly stiffer housing gives it a more stable feel, while the Milky Yellow’s softer housing can feel a bit more “mushy” under heavy use but also more forgiving on the fingers.

If you plan to use your keyboard for both typing and gaming, the Jupiter Yellow’s crisp response may be better for rapid key presses. For purely typing, the Milky Yellow’s deeper sound and smoother post-lube feel can be more satisfying.

Budget and Value Considerations

Both switches are among the best budget linear switches on the market. The Milky Yellow is typically a few cents cheaper per switch, making it ideal for full builds where cost is a major factor. For example, a 90-switch board would save you $4–$5 by choosing Milky Yellows over Jupiter Yellows—enough to buy a nice artisan keycap to personalize your build.

Speaking of personalization, consider adding a Three Pandas Resin Artisan Keycap to your Escape key for a unique touch. Or, if you prefer a metallic accent, the Hammer Aluminum Alloy Artisan Keycap adds a premium look and feel. These small upgrades can make your budget build feel truly custom.

Which Switch Should You Choose?

The choice between Gateron Jupiter Yellow and Gateron Milky Yellow ultimately depends on your priorities:

• Choose Gateron Jupiter Yellow if: you want a smooth, stable, and consistent linear switch out of the box, appreciate a brighter sound signature, and prefer minimal extra work for tuning.
• Choose Gateron Milky Yellow if: you enjoy hand-lubing switches to achieve a buttery-smooth feel, want a deeper, thockier sound, and want to save a few dollars for other components like keycaps or cables.

Both switches will serve you well in any custom keyboard. For instance, pairing them with a Keychron Q2 Pro QMK/VIA Wireless Custom Mechanical Keyboard ISO Layout Collection provides a high-quality base for your switch choice. The Q2 Pro’s aluminum case and hot-swappable PCB allow you to test both switches easily without soldering.

Conclusion: Making Your Decision

In the end, there is no wrong choice between the Gateron Jupiter Yellow and Gateron Milky Yellow. Both are excellent budget linear switches that deliver smooth performance and great value. If you’re after convenience and a bright, clean sound, the Jupiter Yellow is your switch. If you’re willing to invest a little time in lubrication for a deeper, more satisfying typing experience, the Milky Yellow offers an unbeatable price-to-performance ratio.
