Keychron B40 and B39 Alice Keyboards Launch With Extended Scissor Switches

Keychron has expanded its Alice lineup with two new wireless keyboards designed for users who prefer scissor switches over mechanical stems. The B40 and B39 models offer extended actuation distances that improve typing comfort for those accustomed to laptop-style keys. These devices target buyers seeking ergonomic layouts without the bulk of traditional mechanical boards. We see this as a practical option for office workers and gamers who want a lighter touch.

Extended actuation distance targets typing comfort

The B40 features a compact 75 percent Alice layout, while the larger B39 includes a full numpad in a 1800 Alice configuration. Both models utilize ABS plastic construction, which keeps the weight manageable at 595 grams for the B40 and 680 grams for the B39. Neither keyboard includes backlighting, a deliberate omission that supports the advertised battery longevity. The scissor switches are pre-lubricated and compatible with Cherry MX stem profiles.

Spec comparison

Connectivity relies on Bluetooth 5.2 and a 2.4GHz wireless dongle, with the latter supporting a polling rate of up to 1,000Hz. An 800mAh battery powers the devices, providing up to 520 hours of usage in 2.4GHz mode. The 3.5mm actuation distance is 59 percent longer than standard scissor switches, which may require a brief adjustment period for new users. This extended travel aims to reduce finger fatigue during long typing sessions.

The Keychron B40 is priced at 49.99 USD (around $49.99) on the company's online store. The B39 model costs 54.99 USD (around $54.99). Both keyboards are available for global purchase directly through Keychron. These prices position the devices as affordable alternatives to premium mechanical Alice keyboards. Buyers looking for a budget-friendly ergonomic scissor-switch keyboard should consider these options.
