Begali HST Mark III Single Lever

The HST Single Lever key was inspired by a design that several of the top competitors at the High Speed Telegraphy Competition in Pordenone (HST 2008) were using.  Their keys were home made from simple materials, but they were capable of very high speeds in the right hands.  So, we couldn’t resist trying to take that basic design and improve on it – and the result was the original HST key.  Meanwhile it has further evolved into the HST Mark III that you see here.  It uses a heavy cast iron base which makes sure that it will not move.  The single lever is made from aluminum alloy and held by two precision racing

bearings at the back. The finger piece is perforated to prevent your fingers from slipping.  The contact spacing and the tension can be adjusted using gold plated screws with a fine pitch. The return force is created by magnets and an ingenious cam mechanism, which ensures consistency over a wide range of forces and a clearly defined center position.
