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 it’s 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 imbedded in the base, and the moving components are made of a light-weight alloy. This key uses a novel approach with a segmented lever that provides 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.
