For buyers choosing Cherry silent switches, CHERRY MX2A Silent Red is a sensible starting point if you want a damped linear switch—one that actuates without a tactile pressure point. CHERRY specifies 45 cN operating force, 1.9 mm pretravel, and 3.7 mm total travel. Your final choice should depend on the exact part and your keyboard’s documented compatibility. CHERRY’s Silent Red product information supports those specifications.
This guide is for buyers choosing replacement switches, especially when a listing leaves the generation, mounting version, or lighting accommodation unclear. It focuses on documented MX2A Silent Red variants and explains why Silent Black needs further specification checks before a spring-weight comparison.
Source information captured October 15, 2026. This is a research-based buying guide; no hands-on acoustic or force testing was performed. The guide prioritizes CHERRY’s product documentation, uses search excerpts only for their visible assertions, and leaves conflicting specifications unresolved. KBD.news provides generation-identification context; Keychron provides attributed feel guidance.
Quick takeaways
- Start with the full manufacturer part number and generation.
- Verify the switch footprint, socket support, plate fit, LED clearance, and keycaps separately.
- Try an exact-variant sample before committing to a full keyboard’s worth of switches.

Which Cherry silent switches should you consider?
Begin with the current MX2A Silent Red documentation, then identify the exact version being offered. CHERRY lists both RGB and non-RGB part numbers on its Silent Red page. That establishes documented variants; it does not establish which ones a particular seller currently stocks.
For the lighting and mounting checks below, RGB means red, green, and blue; PCB means printed circuit board; and SMD means surface-mount device. Use this table to separate the questions a listing needs to answer:
| Version or part | What the evidence establishes | Buying implication |
|---|---|---|
MX2A Silent Red: MX2A_71NA and MX2A_71NB | CHERRY lists these as RGB variants. | Confirm the complete code and the target board’s lighting clearance; the product page does not resolve both pin counts. |
MX2A Silent Red: MX2A_71NN and MX2A_71NW | CHERRY lists these as non-RGB variants. | Verify mounting independently; non-RGB does not answer the footprint question. |
Exact MX2A-71NA datasheet example | The available manufacturer-datasheet excerpt identifies three-pin Silent Red and accommodation for a PCB-mounted SMD LED. | Use this as evidence for this exact part, then check the board. |
| Older MX Silent Red | KBD.news maintains a separate older plate-mount entry alongside MX2A plate-mount RGB. | Confirm generation instead of treating every Silent Red listing as identical. |
| MX2A Silent Black | CHERRY documents a damped linear switch, but its specification sections disagree. | Obtain a consistent, current part-specific specification before comparing spring force or travel. |
Sources: CHERRY Silent Red, the available search excerpt for CHERRY’s Silent Red datasheet hosted by Mouser, KBD.news’s comparison, and CHERRY Silent Black.
CHERRY’s Red product page uses underscores in its codes; the datasheet excerpt uses a hyphen. Give the supplier the complete code and ask it to confirm the manufacturer identity. Do not transfer the three-pin statement for MX2A-71NA to NB, NN, or NW simply because the names are similar.
KBD.news also warns that its database remains a work in progress. Its separate generation entries are useful identification guidance, but its offers should not substitute for checking the actual package you intend to order.
Why Silent Black needs clarification
The Silent Black product information captured on October 15, 2026 contains two distinct conflicts. Its Highlights and Properties sections disagree on force and travel. Its construction description identifies a dark gray switching slide, while Properties lists a red stem. CHERRY’s Silent Black page therefore documents the variant and the unresolved specifications without establishing a reliable numerical alternative.
If you are considering Black because you want a different spring weight, request the current specification for the exact offered part from CHERRY or the supplier. This guide does not recommend buying Silent Black on an assumed force difference.
What Silent Red's force and damping mean
For current MX2A Silent Red, CHERRY’s published figures answer three different questions:
- 45 cN operating force: the specified force associated with actuation, expressed in centinewtons.
- 1.9 mm pretravel: the specified travel to actuation.
- 3.7 mm total travel: the specified full stroke.
These are manufacturer switch specifications from the Silent Red page. Operating force alone is not a complete force curve, so it cannot tell you everything about resistance throughout the press or how bottoming out will feel to your fingers.
CHERRY describes the Silent stem as a two-component part with integrated noise-reduction technology. It also lists factory-applied lubricant for MX2A Silent Red. Those features explain the switch’s intended damping and preparation without establishing a measured sound result for your assembled keyboard. CHERRY’s construction details describe the component itself.
Bottom-out feel—the sensation when you reach the end of the stroke—deserves a separate decision. The available excerpt from Keychron’s Cherry switch guide describes Silent switches as elastic at bottom-out and different in feel. Treat that as an attributed observation to investigate with a sample, rather than a promise that every buyer will find them softer or more comfortable.
When sampling, ask whether you like the end of the stroke as well as the resistance before actuation. A switch can meet your preference for linear operation while leaving you uncertain about its damped bottom-out. That uncertainty is a good reason to pause before ordering the full quantity.
Reduced switch noise does not guarantee a silent keyboard. The cited component descriptions do not establish that case, keycap, or stabilizer sounds disappear. There is no controlled whole-keyboard acoustic result here from which to promise a decibel reduction.
CHERRY also advertises more than 50 million operations for Silent Red. Read that as a component endurance claim, rather than a prediction of years of keyboard life or a complete-keyboard warranty. The manufacturer’s claim does not resolve those broader questions.
Will the exact switch fit your keyboard?
The strongest specific mounting evidence available here concerns MX2A-71NA. A captured search excerpt from CHERRY’s datasheet hosted by Mouser identifies it as three-pin Silent Red and describes an opening for an SMD LED mounted directly on the PCB. The excerpt says the LED is not included in the switch module.
That supports a bounded part description. It does not provide a universal keyboard fit approval or establish the geometry of every other suffix. Use your exact keyboard model and revision for the following checks.
Confirm the electrical and socket support
Find the keyboard manufacturer’s supported replacement-switch specification. Check that it explicitly covers the intended mechanical contact switch and socket arrangement. A listing that says only “hot-swap” leaves too much unanswered for this purchase decision.
Do not infer approval for optical, magnetic, low-profile, or proprietary replacements. If the board requires soldering or switch modification, stop this drop-in selection workflow and seek board-specific guidance.
Confirm the mounting and plate requirements
Match the exact switch footprint and mounting requirements to the board’s documentation. The three-pin evidence for MX2A-71NA is useful only after the target board’s requirements are known. Do not assume that an unresolved suffix has the same footprint.
Record the supporting document or manufacturer response before ordering. If the seller cannot identify the supplied part, request clarification instead of relying on a family-level product photo.
Confirm the LED arrangement and clearance
For the RGB version, CHERRY describes a translucent lower housing, an SMD LED recess, and housing features that route light from the PCB-mounted LED. CHERRY’s RGB construction description concerns how the switch accommodates lighting.
Check your board’s actual LED position and clearance against the intended part. “RGB” alone does not establish that every LED, switch, and plate combination will fit. For the documented MX2A-71NA example, remember that the LED remains a separate PCB-mounted component.
Confirm keycaps and stabilized keys separately
Ask whether your existing keycaps have the required stem engagement and clearance for the intended switch. If you are buying keycaps too, verify the complete layout, including larger keys. Treat stabilizer compatibility and coverage as separate checks rather than assuming that switch compatibility settles the entire keyboard.
No target keyboard or complete keycap layout has been verified for this guide. These checks are a purchasing worksheet, not approval for an unidentified board.
Sample first, then order the full pack
Once the documentation checks are satisfied, request a small sample of the exact variant you intend to buy. Use the keyboard manufacturer’s approved replacement procedure if you evaluate it in your board. Keep the part code with the sample so you can match the later order.
Evaluate three things: whether the operating resistance suits you, whether you like the damped bottom-out, and whether the sound meets your expectations in your setup. A sample is a personal selection aid; it is not a controlled acoustic test or a guarantee about the finished keyboard.
Use this worksheet before checkout:
| Check | What to record |
|---|---|
| Keyboard identity | Exact model and revision |
| Switch identity | Generation and full manufacturer part number |
| Fit confirmation | Board documentation or manufacturer response covering socket, footprint, plate, and LED clearance |
| Keycaps and stabilizers | Confirmation for existing caps and larger keys |
| Sample decision | Whether the exact variant’s resistance and bottom-out suit you |
| Required quantity | Actual switch positions being replaced, plus your chosen spares |
| Delivered package | Exact code, switches per pack, and number of packs |
| Checkout terms | Current price, availability, shipping, and applicable returns |
Count the actual switch positions you plan to replace rather than estimating from a layout label. Add the spares you want, then compare that total with the seller’s stated package quantity. If the sample and full pack have different or incomplete codes, resolve the difference before paying.
Current seller stock, US fulfillment, prices, and return terms are not verified here. Check those details on the chosen offer after the part and fit questions are resolved.
Frequently asked questions
Are older CHERRY MX Silent Red switches interchangeable with MX2A?
Do not assume interchangeability from the Silent Red name. KBD.news’s comparison distinguishes an older plate-mount version from MX2A plate-mount RGB. Establish the generation and full part number, then check the intended replacement against your board’s documentation. The comparison does not approve every version for every keyboard.
Does an RGB Silent Red switch include an LED?
For the documented MX2A-71NA example, the available manufacturer-datasheet excerpt says the SMD LED mounts directly on the PCB and is not included in the switch module. Confirm the exact package contents and your board’s lighting arrangement before ordering; the RGB label alone leaves those purchasing questions open.
What should I ask a seller whose listing only says “Silent Red”?
Ask for the generation, complete manufacturer part number, mounting specification, lighting variant, and switches per package. Request confirmation that the sample and full pack contain the same part. Use the official Silent Red variants as a reference, while requiring the seller to identify the item actually supplied.
Choose by exact part, then verify the board
Choose Cherry silent switches by combining a documented part with confirmed keyboard requirements. MX2A Silent Red provides verified force and travel specifications; MX2A-71NA adds specific three-pin and PCB-mounted SMD accommodation evidence. Silent Black’s conflicting specifications still need clarification before a force-based choice.
Your next step is to complete the fit worksheet for your exact keyboard, then request a matching sample before ordering the full quantity.
