Keychron C1 有線TKL ホットスワップ対応メカニカルキーボード RGBバックライト

Overview

Keychron C1 有線TKL ホットスワップ対応メカニカルキーボード RGBバックライト — the Keychron C1 wired TKL — is an 87-key tenkeyless mechanical keyboard. The short verdict: it suits people who want a wired TKL with hot-swap sockets, so they can change switches without soldering, and who are fine with a US layout.

It is not the right pick if you want wireless or magnetic Hall-effect switches. It ships with Gateron G Pro Brown tactile switches, connects over wired USB Type-C, and polls at 1000Hz.

It supports both Mac and Windows, with a hardware switch to change the key layout, and Linux is also listed as supported. As of September 2026, the Amazon.co.jp listing had a rating of 4.7 out of 5 from 69 reviews.

That's not many reviews, but satisfaction is high.

One warning up front: the product name says "RGB backlight", but the spec data lists a white LED backlight (adjustable). Check the listing photos and description before you buy to confirm which version you'll get.

The Before You Buy section below covers this in more detail.

Compatibility Guide

It connects over USB Type-C with a detachable cable of about 1.5m.

If your PC only has USB-A ports, check the connector on the included cable in the listing, and buy a USB-C to USB-A cable if it doesn't match. Because the cable detaches, a broken cable doesn't mean replacing the whole keyboard.

Supported operating systems are Windows, macOS, and Linux. Mac/Windows switching happens with a hardware toggle, so you can get the basic modifier layout right without installing a driver.

The original article says the keycaps carry both Mac and Windows legends, but check the printing on the unit you receive.

The hot-swap sockets accept 3-pin and 5-pin Cherry MX-compatible switches, so you can fit linear, tactile, or clicky MX-style switches. Optical switches, low-profile-only switches, and magnetic Hall-effect switches will not work.

The keyboard measures about 357×130×38mm. Without the number pad it's narrower than a full-size board, which leaves more room for your mouse.

At 38mm it's noticeably taller than a low-profile keyboard, though, and tends to make you lift your wrists while typing.

The layout is the easiest item in this table to overlook. If you're used to Japanese JIS keyboards, read the Before You Buy section first.

Product Info

rmation

On Amazon.co.jp the price was ¥17,384 as of September 28, 2026.

Prices change often with sales and stock, so check the current price on the listing before buying. This listing is sold and shipped by a third-party shop (TS Store), not by Keychron directly.

For the same Keychron C1, price, accessories, and warranty handling can differ between sellers.

The Keychron C1 came out around 2020 and sits in the entry-to-mid range of Keychron's lineup. The original article lists a USB Type-C cable, keycap puller, switch puller, spare keycaps, and a manual in the box.

The manufacturer warranty is said to be one year, but when you buy from a third-party seller, support may go through that seller. Confirm the warranty terms before you buy.

Typing Feel and Swapping Switches

Gateron G Pro Brown switches have a small bump at the top of the keypress and no click sound. If you're expecting the loud click of a blue switch, they may feel underwhelming.

On the other hand, they work well in an office or a shared room. The bump is mild, so if you want stronger feedback you can swap in heavier tactile switches later.

That's really what this board is built for.

To swap a switch, grip the top and bottom clips with the switch puller and pull straight up. Then check that the new switch's pins are straight and press it straight down.

A bent pin is the usual reason a single key stops responding. Try one rarely used key first, confirm it works, and then do the rest.

Because the sockets accept 5-pin switches, PCB-mount switches with the extra plastic alignment legs fit without trimming. That opens up enthusiast options such as Gateron's 5-pin Ink series.

How It Compares

When comparing it with other keyboards, it helps to think in three terms: connection, switch type, and size.

The C1 keeps things simple and gets the basics right: a stable wired connection, swappable switches, and support for both Mac and Windows. If those three things don't matter much to you, a board with newer features will probably satisfy you more.

Recommended Users

• First-time mechanical keyboard buyers: The stock switches are mildly tactile, and if they don't suit you, you only need to buy new switches, not a new keyboard.
• People who switch between Mac and Windows: The hardware toggle changes the modifier layout, so one keyboard can move between a work Mac and a home Windows PC.
• Office work and programming without a numpad: The arrow and function keys are separate, so spreadsheets and coding stay comfortable, and your mouse gets more room.
• Gamers who prefer wired reliability: A wired 1000Hz connection means no dead batteries and no pairing.

Before You Buy

Assume a US layout. The seller's name includes "キーボードUS配列" (US keyboard layout).

If you're used to Japanese JIS keyboards, the Enter key shape and symbols such as @ and : are in different places, so expect typos until you adjust. On Windows, you also need to set the keyboard layout to English (101/102-key), or the keycap legends won't match what gets typed.

If you need JIS, skip this listing.

The backlight listing is inconsistent. The product name says RGB, but the spec data says white LED.

The Keychron C1 was sold in several variants, so check the listing photos and description to see which one you'd receive. That matters if you want per-key color effects.

It's a tall keyboard. At about 38mm high, it will feel tall if you're coming from a laptop or a slim keyboard.

For long typing sessions, a palm rest makes your wrists more comfortable.

It lacks the latest gaming features. Wired 1000Hz is plenty for most games, but it has no magnetic-switch rapid trigger and no 8,000Hz-class polling.

If those matter for competitive FPS, start with a magnetic-switch keyboard instead of buying twice.

Check the listing details. In the collected data, the price labeled "Amazon US" actually points to the same Amazon.co.jp page, so it can't be used as an overseas price comparison.

Also, when several sellers offer the same product, listing details from other offers can get mixed in. At checkout, make sure the photos, product name, and seller match the keyboard covered here.

FAQ

Q. Can I use it with a Japanese JIS layout? A.

This listing's seller name says US layout, so it's safest to assume it is not JIS. Set your OS keyboard to an English layout.

Q. Can I switch to linear switches? A.

Yes, as long as they are 3-pin or 5-pin Cherry MX-compatible. Optical, magnetic, and low-profile-only switches won't fit.

Q. Does it work on a Mac?
A. Yes. Set the hardware toggle to Mac and the modifier keys switch to a Mac layout.

Q. Is it RGB? A.

The product name says RGB, but the spec data says white LED. It depends on the variant, so check the listing before buying.

Q. What do reviewers say? A.

As of September 2026 it was rated 4.7 out of 5 from 69 reviews on Amazon.co.jp.

That's a small number of reviews, so use it as a reference and judge the typing feel for yourself.
