Choosing keyboard switches is less about finding a universal winner than matching two decisions: do you want tactile or linear feedback, and does your build call for 3-pin plate mount or 5-pin PCB mount? Kailh BOX Sky Blue and Kailh Box Jellyfish split neatly along those lines. The quick answer: Sky Blue for tactile feel and 3-pin format; Jellyfish for linear feel, RGB pass-through housing, and 5-pin format.
Quick verdict
Choose Kailh BOX Sky Blue if tactile feedback and a 3-pin plate-mount configuration are the priorities. Choose Kailh Box Jellyfish if you want a linear switch with a 5-pin PCB-mount configuration and a transparent housing designed for RGB lighting pass-through. The deciding factor is feel first, followed by the mounting format your keyboard build uses.
At a glance
| Switch | Listed price | Feel | Format and standout detail |
|---|---|---|---|
| Kailh BOX Sky Blue | USD 17.00 | Tactile mechanical | 110 pack; 3-pin plate mount; sky blue stem |
| Kailh Box Jellyfish | USD 12.00 | Linear mechanical | 110-switch lot; 5-pin PCB mount; transparent polycarbonate housing |
Where each product wins
- Kailh BOX Sky Blue: The better match for shoppers specifically seeking a tactile designation, 3-pin plate-mount format, and a sky blue stem.
- Kailh Box Jellyfish: The better match for a linear feel, 5-pin PCB-mount format, and a housing described for RGB lighting pass-through. Its listed price is also the lower of the two.
Product notes
Kailh BOX Sky Blue Tactile Switches
Choose Kailh BOX Sky Blue when the tactile designation is the main reason you are changing your keyboard switches. Its 3-pin, plate-mount format makes it the direct match for a build using that configuration, while the sky blue stem, clear housing, white base, and MX-compatible cross mount add specific design and fit details. The tactile label also separates it clearly from the linear Jellyfish set, so the choice is straightforward when feedback matters more than lighting treatment. One limitation is the 3-pin, plate-mount format: it is not the same as the 5-pin, PCB-mount configuration on the Jellyfish set, making Sky Blue a less direct match for a build designed around that format. It is a focused choice for tactile feel and plate-mount requirements.
Kailh Box Jellyfish Linear Switches
Kailh Box Jellyfish makes sense when a linear feel is the starting point. The transparent polycarbonate housing is described as designed for RGB lighting pass-through, and the 5-pin PCB-mount configuration gives it a distinct format from Sky Blue's 3-pin plate mount. The clear housing also creates a different visual direction from the other set's sky blue stem, which can matter in a color-coordinated keyboard. The tradeoff is straightforward: Jellyfish is identified as linear, so it is not the right match for someone specifically seeking tactile switches. Its five-pin configuration is likewise a limitation for a build planned around three-pin plate-mount switches. Pick it for the combination of linear feel, PCB-mount format, and RGB-oriented housing detail.
Final choice by use case
- For tactile feedback: Choose Kailh BOX Sky Blue, whose listed type is tactile mechanical.
- For a linear feel: Choose Kailh Box Jellyfish, whose listed switch type is linear.
- For a 3-pin plate-mount build: Choose Kailh BOX Sky Blue.
- For a 5-pin PCB-mount build: Choose Kailh Box Jellyfish.
- For RGB lighting pass-through: Choose Kailh Box Jellyfish, whose transparent housing is specifically described for that purpose.
- When listed price decides the choice: Kailh Box Jellyfish is USD 12.00 versus USD 17.00 for Kailh BOX Sky Blue, a $5 spread.
Both sets are listed as new mechanical switches, so the meaningful choice is the tactile-versus-linear feel, mounting format, and housing or stem appearance.
