Choose low profile keyboard switches by your exact keyboard model, revision, and supported switch generation before comparing tactile feel. NuPhy’s official support information, for example, separates Air V1/V2 switch support from Air75 V3 support because of pin structure. A familiar brand or similar-looking switch is insufficient evidence of fit. Source: NuPhy support.
This guide is for owners replacing switches and builders checking a proposed parts combination. It covers platform identification, tactile specifications, and purchase checks. Silent-switch comparisons, scissor-switch repairs, and full-height switch recommendations fall outside its scope.
Quick takeaways
- Find your keyboard or printed circuit board (PCB) revision and its documented switch support first.
- Check PCB/socket fit, plate retention, keycaps, and stabilizers separately.
- Compare the exact KS33 2.0 variants below only after confirming the appropriate platform.
- Require separate board-fit confirmation for Sunset; its specifications do not establish interchangeability with Gateron switches.

Match low profile keyboard switches to your board
For this buying decision, treat a switch platform as the documented combination of electrical system, mounting arrangement, and supported switch family. Record whether your board documentation specifies mechanical, optical, or magnetic switches. Then look for explicit support for the replacement’s exact family and generation.
Start with the keyboard’s complete model designation, including its version. For a custom build, use the PCB revision and the intended plate and keycap specifications. If documentation only says “low profile” or gives a pin count, ask the manufacturer to identify the supported switch models before ordering.
Gateron supplies a useful boundary: both its white-bottom KS33 2.0 and KS33 2.0 Banana pages restrict replacement use to keyboards designed for Gateron low-profile switches. Neither page establishes a universal low-profile replacement standard. Sources: KS33 2.0, KS33 2.0 Banana.
NuPhy shows why the generation matters
NuPhy’s captured support passage gives the following manufacturer-stated support:
| Keyboard designation in NuPhy support | Listed switch support |
|---|---|
| Air V1 and V2 series | Gateron Low-profile 2.0; Cowberry, Moss, Aloe, and Wisteria switches offered by NuPhy |
| Kick75, Node, and Air75 V3 | Gateron Low-profile 3.0 and NuPhy Panda nano |
NuPhy attributes this separation to pin structure. These are documented system recommendations, rather than results from an aftermarket compatibility test. Source: NuPhy support.
Gateron’s separate KS33 3.0 passage lists five pins and specifically names NuPhy Nos75, Kick75, Air75 V3, and Node75 as suitable keyboards. The KS33 2.0 pages list three pins. Keep those generations distinct; the shared KS33 name does not authorize substituting one for the other. Sources: KS33 3.0, KS33 2.0.
Notice that NuPhy’s passage says “Node,” while Gateron names “Node75.” Use your board’s full designation when confirming support. Avoid extending either list to an unlisted model simply because it belongs to the same product family.
Check height, PCB, plate, keycaps, and stabilizers
Once the switch family passes the board-support check, examine the physical assembly. Gateron’s platform restriction establishes a starting point, but the available specifications do not resolve every custom PCB, plate, keycap, and stabilizer combination. Use the worksheet below to request the missing details. Source: Gateron KS33 2.0.
| Check | What to record or confirm | Keep the purchase pending when… |
|---|---|---|
| Board and electrical system | Exact keyboard/PCB revision and manufacturer-supported switch generation | Support is described only as “low profile” |
| PCB and socket | Supported footprint, pin positions, and socket or soldered installation requirements | Only the number of pins matches |
| Height and plate | Dimension reference points, housing clearance, and plate retention requirements | You have a height number without assembly documentation |
| Keycaps | Exact stem interface and clearance throughout the intended stroke | Compatibility rests only on a stem photo or broad “MX-compatible” label |
| Stabilizers | Documented alignment and clearance for the intended larger keys | Only an ordinary single-key fit has been addressed |
Treat an unanswered row as an unresolved purchase question. Send the board maker the exact switch model and ask for confirmation with your existing plate, keycaps, and stabilizers. For a build, ask about the proposed combination before treating the parts list as complete.
Compare height labels on the same basis
Gateron states that KS33 is 12.2 mm high and KS27 is 11.75 mm high. Kailh’s Choc V2 passage gives an 8.6 mm switch-body thickness. These labels do not provide a common measurement basis for ranking installed keyboard height. Sources: Gateron KS33, Kailh Choc V2.
Ask which surfaces each dimension measures and how the switch sits in the intended assembly. Neither the height figures nor the Choc V2 body-thickness specification establishes Choc V1/V2 interchangeability or arbitrary keycap clearance. A smaller published number should not replace an assembly-fit check.
Compare low profile tactile switches
After confirming the platform, compare exact tactile variants using their published labels. Keep operating force separate from tactile force, and keep pre-travel separate from total travel. The table preserves the terminology and tolerances supplied by each source.
| Exact option or specification row | Published force | Published travel |
|---|---|---|
| Gateron KS33 2.0 white-bottom page: tactile row; Brown is offered on the same page | Operating force: 55±15 gf | Pre-travel: 1.7±0.4 mm; total travel: 3.2±0.2 mm |
| Gateron KS33 Low Profile 2.0 Banana | Operating force: 60±15 gf | Pre-travel: 1.7 +0.4/−0.3 mm; total travel: 3.0±0.2 mm |
| LowproKB Sunset, CPG135001D02-3 | Operating force: 40±10 gf; tactile force: 55±10 gf | Conduction travel: 1.5±0.5 mm; total travel: 3.0 +0/−0.5 mm |
Sources for the respective rows: Gateron white-bottom KS33 2.0, Gateron KS33 2.0 Banana, and LowproKB Sunset. Force values use gram-force (gf); travel values use millimeters (mm).
KS33 2.0 Brown and the white-bottom tactile row
Use the white-bottom page as the specification reference when that is the exact product you intend to order. Its readable table labels the row “Tactile,” while its option selector separately names Brown. Preserve that distinction when matching a seller’s product description to the official listing. Source: Gateron white-bottom KS33 2.0.
This is a candidate to investigate when your board supports the appropriate Gateron 2.0 platform and you want the regular Brown option. Confirm the exact variant rather than applying this row to every product sold under a KS33 or Brown name.
KS33 2.0 Banana for Gateron’s stronger-feedback description
Gateron describes its KS33 2.0 Banana as having heavier, more pronounced tactile feedback than its regular low-profile Brown. That manufacturer description makes Banana a reasonable candidate to investigate if you want that change within a documented compatible platform. It is not a measured comparison from this guide. Source: Gateron KS33 2.0 Banana.
The published operating-force tolerances also deserve attention. The white-bottom tactile row’s 55±15 gf corresponds to 40–70 gf, while Banana’s 60±15 gf corresponds to 45–75 gf. Those ranges overlap, so the nominal values alone cannot establish how every individual sample will compare.
Sunset as a separately identified tactile option
LowproKB identifies Sunset CPG135001D02-3 as a tactile switch designed by LowproKB and manufactured by Kailh. Its listing supplies both operating force and tactile force, making it a useful example of why a single advertised force number needs a label. Source: LowproKB Sunset.
Do not compare Sunset’s 55±10 gf tactile-force value directly with Gateron’s 55±15 gf operating-force value as though they describe the same point. Consider Sunset only after confirming support for that exact model with your board and keycaps. The available passage does not establish your target assembly’s fit.
What travel and force specifications leave unanswered
Use pre-travel and total travel as separate selection fields. For Sunset, retain the source’s “conduction travel” label when recording specifications. The supplied values do not include complete force curves or establish the tactile bump’s position for these options. Sources: KS33 2.0, Banana, Sunset.
Avoid turning those specifications into promises of faster typing, lower noise, or reduced fatigue. Choose candidates using documented fit and the labeled specifications, then evaluate personal preference separately if a suitable sample purchase is available.
Order the exact replacement model and pack
Use official product and support links to establish identity before choosing an offer. This guide does not establish current seller inventory, pricing, condition, or return terms. Check those details on the actual offer you plan to purchase.
Before checkout, confirm:
- Board identity: The complete keyboard model and revision match the support documentation.
- Switch identity: Manufacturer, family, generation, and variant match the intended replacement.
- Assembly fit: PCB/socket, plate, keycap, and stabilizer questions are resolved.
- Quantity: The pack contains enough of the chosen switches for the positions you intend to replace, plus any spares you want.
- Offer terms: Seller identity, condition, shipping destination, and returns are acceptable, including any restriction on opened or installed switches.
Reject an ambiguous listing until its exact model is clarified. A color name, nominal force, or pin count should not substitute for a complete product identity.
Worked example: an Air75 V2 owner considering Banana
An Air75 V2 owner should begin with NuPhy’s Air V1/V2 support statement for Gateron Low-profile 2.0. Next, identify the candidate as KS33 Low Profile 2.0 Banana, then resolve the fit worksheet for the existing assembly. Gateron’s stronger-feedback description can guide the preference decision after those checks. Sources: NuPhy support, Gateron Banana.
For an Air75 V3 owner, the documented starting point changes to Low-profile 3.0 or Panda nano. Do not carry the V2 replacement choice over to V3 based on the Air75 name. Source: NuPhy support.
Frequently asked questions
Does a matching pin count prove compatibility?
No. Treat pin count as one specification to verify alongside the exact board-supported platform and generation. Gateron restricts its KS33 2.0 replacements to the appropriate Gateron low-profile platform, and NuPhy explicitly separates supported generations because of pin structure. Sources: Gateron KS33 2.0, NuPhy support.
Is Banana more tactile than Brown?
Gateron describes KS33 2.0 Banana as heavier and more pronounced in tactile feedback than its regular low-profile Brown. Use that as attributed manufacturer guidance. The available evidence does not supply measured comparative force curves, bump positions, or a guarantee of your preferred feel. Source: Gateron Banana.
Can I keep my existing keycaps and stabilizers?
Confirm that exact combination with the board maker before purchasing. The named NuPhy support lists establish switch-system support; they do not promise every aftermarket keycap, plate, or stabilizer combination. Keep keycap clearance and larger-key alignment as separate questions in your fit worksheet. Source: NuPhy support.
Choose by documented fit, then tactile preference
The useful shortlist for low profile keyboard switches starts with your board’s supported platform and generation. Within an appropriate Gateron 2.0 system, investigate the exact white-bottom Brown option and KS33 2.0 Banana using the specifications above. Treat Sunset as a separate model requiring its own fit confirmation.
Your next step is to complete the fit worksheet with your board’s full model designation and intended switch model. Resolve any unanswered compatibility question with the manufacturer before selecting a replacement pack.
