When gutting the phone, I went to the trouble to preserve the hook and PTT switch infrastructure. I’m still not sure how I’m going to use them, but I figure that it’d be good to know how they work.

Not that any of you care, but if you want to know how they mapped, it’s below the break.
The PTT switch is a simple SPST leaf switch, and it serviced by the lighter and separate green and red wires.
The hook switch an ugly set of leaf switches, but the effect is a DPDT switch.
