Care & Feeding of TT keys

[Greg G.]

Is removing keys from a TT keypad a pita?  I want to remove the ones from the orange mutt phone I got to clean them, but I don't want to start digging into the keypad until I know more what's involved.  The workings are actually a 72 NE.

Yes it is supper PITA. Most old style TT pads. 25,35 type. It is to much labor to rebuild a tt pad. The only thing i do is clean, adjust the contacts and tune it to the correct Frequency.
I've refurbished over 2000 phones (mostly 1A2) and only tried 1 time
to put a we tt pad back together.  There are springs under each button, and
7 electrical contacts that make the row and columns.  I rebuild (take apart) the key strips for new style call directors and 6/10 button wall phones and they are much easy er to work on but still a pita. You would be much better off replacing the tt dial if you cannot clean it up.

So I found out...

I'm looking for a NE keypad.  I have available parts for the same in a baggie...

I used to have some spares of these - I will check and let you know if I still have spare NE ones. I may have used up all the spares I had. They differed from the WE ones in a few ways, not just the colour coding of the wires, but in that they had a built-in polarity protector. resulting in polarity not being an issue with them.
