"Power Switch and Power Supply" proactive replacement on D-pack?

[bollar]

Speaking of @qwk's "no mention of it (even on the itemized work order list)"... My repair order has this item included:

I was in for new tires and was also advised I should get this done on my B pack VIN P02xx. It took two days, was documented in the repair order, along with a bunch of other stuff, like adding zip ties to certain hoses, replacing floor mats that were curling, broken visors and an "active louver" update. It was a seamless experience for me, though I probably could have shaved a day off the work, had I known they needed a discharged battery.

They have a resistive heater setup that dumps the battery power into something like a 15kW heating element and can drain a full standalone pack to safe levels in 4-5 hours. I'm told the "procedure" for draining the battery when this device is in use is to turn the cabin heater on full blast "HI", which can drain a full battery in a regular work day shift.

Received a call from Tesla last week to proactively replace my power switch, I have a B pack.

I just received a call to replace my power switch as well. I am VIN 32xx with a refurb B pack.

Does anyone know what this power switch is? Where it is on the car, what its function is, etc?
