The shield switches consist of two dark blue-purple twisted pillars with a few red lights on them and a switch between them which can be flipped. They can be found in various locations across the Black Comet and are used to control the Black Comet's defense systems.
Four shield switches appear exclusively in Final Haunt. In the Dark Mission for this Stage, the player has to activated these switches. Said switches are activated when using any kind of weapon on them, even the Vacuum Pod.
