- "I calculate an 85% probability that this is an energy-generating device. It appears that it will activate if the center is rotated. This mechanism is the same as the one you previously encountered that required four gemstone switches to be struck in the correct order. On the left and right, you will find steering wheels with their upper halves painted red."

Gemstone Switches are objects from The Legend of Zelda: Skyward Sword. They have four gems placed at the top, bottom, right and left of the switch. They can be activated by using most of Link's projectile weapons. Link must hit gemstone switches in a certain order to break the lock. This type of switch appears twice in the game, once in the Ancient Cistern and again in the Sandship.
