In this post,

Larry Irwin and Tim Plummer discuss using a "Tri-Tail Switch". My Google searches provide only this post, and un-related junk.

"But they were in trouble. Their old system's data had been mangled and it took the vendor too long to figure it out before the problem had been migrated to all their backup tapes... So - we stepped in, got what data we could with a tri-tail switch (remember those? I still have one...) in place of a serial printer and converted it. "

"great to hear you still have a tri-tail switch used one one time to salvage a reconstruct on a Mark 8. We saved some data but lost much more it was a catastrophe."

Does anyone know what this device is that they are referring to?

Thanks all, as always!

My guess is simply what we used to call an AB or ABCD switch. Basically a manual switch for selecting one of several serial or parallel sources or destinations.

Still made as far as I know--just never heard one referred to as that. Must be a regionalism.
