These knobs and switches control part of the Flight Deck lighting when the orbiter was powered up. The lights behind every switch and fuse created a lot of heat but nothing compared to the running computers, all requiring a cooling system. Inside of the Crew Module, the coolant loop contained water because it wouldn’t be hazardous to the crew unlike the Freon used in the remainder of the orbiter. As part of the decommissioning process, both required draining for safe museum display so Endeavour can never again be powered up.
