Signalling or Morse Keys
On this page you will find various Morse keys, officially called "key
& plug assembly no...".
These keys were used together with the wireless sets shown on my site.
They are in various conditions and still need to be worked on. All in good time...
& Plug Assembly No. 8,
It has a built-in "Send / Receive"-switch.
In this particular unit, the Send / Receive switch is not used. The cable is modified with a standard PL-55 plug, the wires coming from the switch are disconnected. Thus modified, it can be used with a WS19.
the back, a brass pipe is mounted. The only use for this as far as I can
think of, is to store the plug. One of the greatest mysteries of World War
Well, I know that, now. It is for storage of an antenna wire adapter used with the WS18. This adapter goes in the antenna mount, at the side of the WS18 an facilitates the mounting of a wire antenna.
Note that the entire key is made of Bakelite, all others on this page are made of steel.
& Plug Assembly No. 9, CDN
Made by WESTCLOX. This key is found in the "case spare parts no. 5 C" as supplied with the WS 19. It was also supplied with WS 52.
The plug is marked "PL-55".
The canvas straps are different in size: the biggest strap fits the bigger part of the thigh. One has to think of everything!
|The end of the bar is covered by an insulator to prevent electrical shock. (See also "standard key")|
& Plug Assembly No. R11850
I don't know yet to which radio this one belongs.
|Inside is the "standard key". Notice the different angled "U"-shapes. On it is an inscription: "key wt 8 amp no.2".|
Remote Control Unit L no. 2 - ZA 29007
P.C. no. 92181
This device I picked up on a flee market. I paid a non-flee market price, however.
It belong to the WS 62, which I am restoring. In fact, to the WS62 it is a "Remote Control" unit.
the previous owner cut off the webbing leg straps and he also changed the
wiring. He lost the screws as well.
In time this will be restored to original.
is the standard key as used on a Wireless
Remote Control Unit no. 1 (CANADIAN).
This one was completely jammed by corrosion. I took it apart, cleaned and reassembled it. It works well, again.
Using this key on the Wireless Remote Control Unit no. 1 (CANADIAN) could result in a high voltage strike, when connected to the WS 19. The metal parts carry high voltage when transmitting CW. Later models were fitted with a insulating cover.
It was used with AN-GRC9 (Angry-Nine) and many other sets.
The key itself is typed J-37, a very common type, but mounted on a spring steel leg clamp it is designated J-45. The original cable is missing.
This key is used, clamped on the knee. Many operators complained about the blood circulation in the leg being cut off. After 30 - 45 minute in use, one gladly takes it of the leg.

|The construction of the key itself has become a standard for many
All parameters are adjustable to the operators wishes: pressure of the bearings, spring pressure and contact gap.
|Production stamps. Manufactured in month 3 of the year 1952. Oops! Too young for my collection!|
This one I bought through an ad on a Dutch flea market website. The seller
offered this key with the following text:
"For Sale: My old brass key with which I once obtained my diploma radio operator/telegrapher. The key was named SEINSLEUTEL INSTRUKTIE J-44395805-17-039-4197 VR 2200.8872.11. Unfortunately the identifying plate has gone. It comes from the Simon Stevin Barracks at Ede. Then, 1975, this key had already been mistreated for decades."
Thanks, Chris. I won't tell anyone.
Its a very solid key that will last for at least another century.
"Bathtub" Morse key Ref. N°. 10A/7741. This is a key I obtained at the
Rosmalen Radio Flea market, on March 12, 2011. I had been looking for such a
key for along time. Why? I will tell that story on a different page,
click here to go into the tub.
This key's housing is made from Bakelite and its design is water and spark-proof. So it was used in environments where sparks could cause explosions, as on board of planes. It was used on most wartime planes.
