Kailh

Kailh, short for Kaihua Electronics Co., Ltd., is a Chinese manufacturer of mechanical keyboard switches and related components. The company has operated since the late 1990s and is headquartered in China, where it designs, manufactures, and supplies a broad range of switch products used by keyboard makers and enthusiasts worldwide. Kailh positions itself as a major supplier in the mechanical keyboard market, competing with other switch manufacturers.

The Kailh product line encompasses several families designed for different use cases. The BOX switches feature a boxed housing intended to improve dust and moisture resistance, and are produced in linear, tactile, and clicky variants. The company also develops low-profile switches, such as Choc and Jalapeño, for slimmer keyboard designs, as well as gaming-oriented or performance-focused variants that emphasize faster actuation. In addition to the BOX and low-profile families, Kailh has produced various other switches aimed at different actuation characteristics and key feel.

Kailh switches are widely used in both original equipment manufacturer (OEM) keyboards and consumer boards, providing an alternative to other popular switch brands. They are generally compatible with most MX-style keycaps, though some Kailh designs may have housings or stems that require compatible keycaps. The company distributes its products through global channels, including distributors, retailers, and keyboard brands.

In the broader market, Kailh is recognized as a major supplier that contributes to the diversity of mechanical keyboard options available to users. Its ongoing development of multiple switch families helps expand choices for different preferences, budgets, and keyboard form factors.
