>>6051851Here's a look at the voice activation switch. The tiny black box in the middle there is the switch itself. The blue stuff and springs is all just fluff.
The yellow wire goes to an IF switch that changes the lines depending on whether or not Fort Max's visor is flipped down and activates a sound when it's pressed in or out. Brown goes to the battery box, black is presumably the ground. I forgot to see where the purple one goes. It's probably a trap and causes Cerebros to explode if I were to cut it.
