Overview

ELECOM's V custom line includes the TK-VK520LWH, a 75% mechanical keyboard built around a Japanese key layout. With 85 to 86 keys, it trims the footprint enough to free up desk space for wide mouse movement while keeping a familiar 19.0mm key pitch.
The switches are linear reds with a 4.0mm travel, a 1.9mm actuation point and a 50g operating force. That light, smooth feel suits rapid repeated presses and long typing sessions alike, and the near-standard key spacing helps the smaller chassis feel less cramped than its size suggests.
Connectivity is the headline feature: USB wired, USB 2.4GHz wireless and Bluetooth Low Energy, with a switching function that remembers one device per connection type. A single keyboard can therefore serve a gaming desktop, a secondary machine and a tablet. The report rate reaches up to 1000Hz, so the wireless modes are not an afterthought for gaming.

Connectivity & Compatibility

The TK-VK520LWH offers three connection paths: USB wired, USB 2.4GHz wireless and Bluetooth wireless using Bluetooth Low Energy. On the Bluetooth side it works with the HOGP (HID Over GATT Profile) standard.
Supported systems are Windows OS machines equipped with a USB port, or Windows OS machines that support Bluetooth HOGP. The switching function is laid out for one wired device, one 2.4GHz wireless device and one Bluetooth device.
Battery life is rated at up to roughly 450 hours of continuous operation with lighting off, which keeps charging chores infrequent. The report rate tops out at 1000Hz. The layout is Japanese, the key count is 85 to 86, and the key pitch is 19.0mm.

Product Info

The TK-VK520LWH sits in the mid range: it pairs a Japanese layout with a 75% form factor, adds linear red switches, three-way connectivity, a 1000Hz report rate and long wireless endurance, and packages them at an approachable price. That makes it a sensible first compact keyboard for someone stepping down from a full-size board, or a flexible second board for a multi-device desk. The white finish also suits lighter desk setups.

Best Use Cases

  • Gamers who want more desk space: the 75% body and 19.0mm pitch leave room for mouse sweeps, and the 1000Hz report rate keeps input responsive. Not ideal for anyone who relies on a dedicated numpad.
  • People juggling a desktop and a secondary machine: one wired, one 2.4GHz and one Bluetooth slot let you hop between devices without replugging. Not for simultaneous multi-host typing.
  • Writers and office users who prefer a light touch over silence: the 50g linear reds reduce finger fatigue, and up to about 450 hours with lighting off means fewer charging breaks.
