Up at the start of this you said you took it apart, was not sure why you would take a new switch apart, but maybe that has something to do with it.
I took it apart because the aftermarket '28-'29 switches are known for not working out of the package. When I took it apart the contacts didn't touch with the plunger pulled back, so I fixed that issue before installing it.

I'm using a later dual circuit master cylinder, not a factory style early Ford with the rear mounted switch.

Exactly!

That is where the '28-'29 switches are mounted, I'm using the earlier switch on my '30.

I've been tied up all week but I plan to get some shop time in tomorrow and figure what's going on.
