Power Conduit (Metroid Prime Hunters)

The SW Power Conduit is a switch in the subsection of the Synergy Core in Metroid Prime Hunters. Blue in color, it is sensitive to projectiles and four of them exist in the corners of the room. Shooting them will garner a Shield Key to obtain the room's Alimbic Artifact, the final one required to reach the Stronghold Portal and the first Octolith.

What exactly "SW" stands for is unknown.
