BUD switch

The BUD Switch was a block that was possibly planned to be added in the Redstone Update for use with redstone circuitry. BUD stands for Block Update Detector.

Configurations of such a device have existed in Minecraft due to a glitch labelled as a "feature", allowing circuits to detect block updates. This block would simplify the process into one block.
