The BBN Linear Switch from BuiltByNim was designed by renowned keyboard enthusiast Nim to offer a very smooth, linear typing feel with a distinctive sound profile. According to the manufacturer, the switch is aimed at users who value sound, feel, and material selection – it is part of a limited series that is respected in the mechanical keyboard community.
Special features include a "long pole" stem, high-quality materials and a dual-stage spring, which creates a specific sound character when actuated: a rather deep "thock", combined with a cleanly defined bottom-out action.
Overall, this switch is suitable for demanding users looking for a high-quality upgrade for mechanical keyboards – for example, in the custom keyboard sector.
