The switches on the NNBS shifter have resistors built into the shifter itself for shifting the tranny. If you want to use them for something else you'll need to open the shifter and mod it.
Called a momentary switch. Found that out about the fog light switch. Just send a signal to another switch in the computer/relay. Not exactly your basic on/off type.
@ScottyBoy is who had the info. But not sure if Hes played around with shifters

I'm not sure that it is just momentary or if it has resistors like @Rocket Man says. Haven't had a chance put the tester on it yet. Momentary just means that the switch lets go when you stop pushing it, as opposed to a sustained switch. It may have resistors so that the +/- return different values so the computer can tell them apart on the same input.

Yes it's a momentary switch but it also has circuitry built inside the shifter. I checked mine out before I installed it and I forget the exact values but when you push the + it's like 220 ohms or something and when you hit - it's like 400 ohms or something like that. It only uses 2 wires for the + and - command to the TCM so it needs to have 2 different values in resistance. Guys have tried to modify them to use the switch for other things but I've never heard of anyone successfully making it work for anything else.

You are correct about the foglight switch. It send a quick pulse to the BCM which is what then actually turns the fog lights on and off. Most other switches are actually the same way now. As far as the shifter, I have never actually messed with one. I have seen video of a member on another truck forum who used the switches in the shifter to trigger his airbags on his air suspension. No clue what all he had to do in order to get them work like that, but I do know that they triggered relays. Can they trigger a relay with that much resistance on the switch? I honestly don't know, and the guy on the other forum never mentioned anything about it. He only mentioned having to wire up relays.

NBS fogs go through the bcm?
