EVA/IVA Switchbox Assembly, 4 x 6 x 3, bearing an affixed parts tag reading: “Switch Box Assy—EVA/IVA, Stk No. 06362, Part N36-85502041, Contr. NAS9-150, Serial PAD4103, Mfr Code 03953.” Below is a broken North American Aviation inspection seal, and an additional inspection tag is attached to the main cable. The top of the box features two switches for “Low Suit Press Sig” and “Audio Warn Sig Mon,” as well as two connection ports. In fine condition, with scattered dings. This switch box was an early attempt to integrate a A7L Spacesuit umbilical EVA/IVA mode selector into the Command Module telecommunications system. With the implementation of the Block II CM Telecommunications system, the switch box design was rendered obsolete.
