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.
