[Elecraft] PTT switch for K3

[Ralph Parker]

I've been using foot switches since 1957, with my Viking II and 75A-4. 
The first one was somewhat crude.
IMHO, the Linemaster series of industrial-strength footswitches is the 
best. Very rugged, but responds to a light touch.
Mine gets used a LOT, and I expect it to outlast me!
