The Mono Basic is our least expensive single lever key, combining the base of the Simplex Basic with the mechanism of the Simplex Mono. Despite its lower price, it is a very capable CW instrument that can hold its own against many far more expensive keys on the market. Like our other keys, it is manufactured using NC machinery for absolute precision. Micro-threaded screws are used for all adjustments. The pivot uses ball bearings that are embedded in the base, and the moving components are made of a lightweight alloy. This key uses a novel approach with a segmented lever that provides a decoupling of the two sides and an exceptionally well-defined neutral position. The contacts are 925/000 silver. The key comes with a protective dust cover.

If you come from a history of using mechanical bugs or straight keys you may find the operation of a single lever key easier than the “squeeze” mode of iambic paddles. And even if you are using a dual lever key today you may want to get this precision key for an occasional diversion to create dits and dahs in a more old-fashioned way.
