The Simplex Mono is a single lever key with a heavy (1.4 kg or more than 3 pounds) gold or palladium plated base and gold plated components. This photo shows the palladium plated base - for a visual impression of the gold plated base and the dust cover, take a look at the Simplex. You can also select a base with a jet-black titanium finish - for a visual impression take a look at the Simplex Professional key. 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.

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 its sheer beauty and the occasional diversion to create dits and dahs in a more old-fashioned way
