[CW] Higher Quality Straight Keys from China

[Roy Koeppe]

I notice many straight keys are using a high ratio of knob distance 
travel to contact travel. To me this is undesirable because contact 
travel distance becomes nearly 'microscopic' and very critical. I'd 
locate the contacts very near to the knob for maximum travel; even 
things like bearing play then become less sensitive to the contact gap 
being affected. Why reduce contact travel at all?
