I think it's dsk who suggested rewiring a WE 500 set by using the off-normal contacts (white dial leads) to short the entire phone (as in AE 40s and WE 302s) rather than just the receiver. The 10A dial on a Trimline doesn't have the additional contacts since *most* people don't try to listen and dial at the same time.

Yes that's right. My guess are still; we need to increase the voltage difference between just off-hook and rotated dial in hold position. The Trimline doesn't have any anything making it possible to sense that. Now its time for experimenting, how to solve that without ruining the phone.
At this moment I have no solution.

Looking at this page.....

What about TT pads that have all wires? It says thge "F" corresponds to green wire but what if the TT pad has all wires and no terminals?

Author is quick to recommend cutting of "all" other wires but I suspect on many tt pads that terminal corresponds to a wire.

I have used that method on a few phones, it works great. He does have a list of recommended pads, I would guess not all would work for this.

He states the following:

        "Make sure the pad you use has a diode bridge (polarity guard) so your finished phone wonít be polarity sensitive.  Figs. 1a-1c are recommended units.
 
        Figs. 1a and 1b are pads from Premier 2500 phones, made by North Supply.
 
        Fig. 1c is an ITT #42 pad (my favorite).
 
        You can use a Western Electric #72 pad, but Iíve been told they have a high failure rate due to poor switch contacts."


When I made mine, I didn't start until I found a couple of ITT #42s and never had a problem after construction. I didn't try to re-invent his work or to bench test other TT dial pads. Just went with what he recommended and very happy with the results, using Stub's generic mod to fit all phones.

I used all the tt pads that Stan listed and all worked great , I use mostly the Premier 2500 phones, made by North Supply just because I had a bunch on hand from busted phones. The ringer control also works great too on the LB phones !   stub

How did this end up under this thread?? It was posted under its own topic and has nothing to do with VoIP rather Dtmf pads
