CCW key

by OH6DC

Based on idea suggested by SM4FQW

 

Morse code telegraphy (CW) is turned to a whole new direction with a CCW (counterclockwise) keying system:



The heart of the key is this key.




A door lock is also needed.




When the key is turned counterclockwise (CCW) the lock bolt comes out...




... and touches this piece of pc-board.




Keying wires go through the pc-board holes.




CCW key fully assembled and ready to key counterclockwise CW.
