Connecting a straight key

 First time ever I connected my straight key. A Tsjech military key. I think a lot of amateurs have these keys as you can find them on many radio markets. I found a dutch site with description which mentions it is a WW2 key. But the key is way to new for a WW2 key. I found another site in the USA which mentions it is made in the 1950s. Nice to that PRIJEM means RX and VISILANI means TX. This key has a switch in the cover which switches the key off when it is open. It also has a separate switch which turns on when the knob is pulled up. That is used to switch the original transceiver in RX. 

See the 2 contacts in the cover.

I wanted to solder a female 3,5mm connector to the wire. But the wire is probabely made from stainless steel. You can't solder it. 

Inside the key. The second contact is visible (red wires) those are not connected.

Decided to completely remove the cable. You see the strange kind of wire that was used. It probabely was made to last but not really usable for hamradio I think. Although the American website I previously mentioned showed how to connect an alternative way I think the long cable is not really handy in my shack. So this is what I did:

This is how it is connected to my radio now. Just a female connector and no long wire from the key.

And this is the result in the end:

Not bad I think for a first time straight key keying...
