Just beginning my journey into CW and found a straight key that I think will be good to learn on. I have a small DIY kit (UltraPico Kit) that I am going to practice on but I was trying to find a wiring diagram on how to correctly attach the audio cable to the German Junker key. I see there are three contacts points on the key itself but my audio cable only has two wires. Does it matter which wire goes to the contact points on the key?

This site suggests using the front contacts for keying and the rear contacts for T/R switching.
