CW Project Underway

I purchased a CW Touch Key Kit which came in on Friday. It was easy to assemble and I have it taped to my desk using drywall ceiling buttons as code keys. My plan is to design and fabricate a Code key.

So far I’ve manage to design the key around the Touch kit.  Here are some of the drawings

The plan is to have two sets of keys. I am not sure what style I wanted so I figured I’ll do both. The base and vertical stand will be laser cut using 3/8″ Steel plate for weight. The enclosure will be 16ga (.062″) Steel with welded corners and the keys will be punched out of 16ga brass.  The vertical keys will be secured using extruded plastic washers to prevent any contact with the other keys and it’s metal base. The Horizontal keys will appear to be floating. However they will be inlayed into 1/4″ Plexiglas. I plan on using a DPDT Switch to activate one set of keys while disabling the other set. The only issue I see that the wires are sensitive to the touch and the switch might cause an issue.
