It's a transfer switch...usually used in conjunction with 2500 sets. I've 'em used in jails or other places where they want to control access to dialtone. But I've also seen two position varieties where one position is "normal" while the other gives access to "line #2", ringdown, emergency call or other specialty circuit.

What a bunch of smart people!

I remember only installing one TKM-12...

One time we ordered TKM-6 switches for sharing fax lines, et cetera and the Main Office couldn't understand why we shipped the TKM-6F's back! :shrug:
