Apollo-era Command Module Uprighting System circuit breaker panel assembly, 12 x 4 x 11.75, with front of the panel featuring two circuit breakers for air compressors labeled at the top, “Uprighting System,” and two pyro breakers labeled, “S IV B/LM SEP.” Interior bears numerous stamps referring to assembly part numbers, with the original manufacturing tag still attached: "MA 368415, Pt. Name. N/A, Pt. No. V-36-452170-81, Chg. 'H,' S/N No. 06362-AAJ0055, Acct. No. N/A, Rel. N/A, Contr. N/A, Dept. 668." In fine condition. This panel was used to supply power to the uprighting system deployed after Command Module splashdown. It includes four protected circuit breakers to prevent accidental actuation, and a motorized switch that controlled power to the uprighting system. The terminals and wiring are coated with the fire and moisture-resistant sealing. This system was installed on all Command Modules and would be activated after splashdown if the CM landed upside-down or on its side. The activation of the compressors inflated three spheres at the top of the capsule causing the capsule to attain proper orientation onto its main heat shield and allow the astronauts to exit through the main hatch.
