I can kind of see how this is a duplicate, but when searching for this specific problem I could not find an open or unresolved ticket. Thus creating a duplicate if you keep one open (unresolved), perhaps less duplicates will form, just an idea.

Edit:
I've also watched the video from MC-11193. In my opinion this is not a duplicate.
Could you ([Mod] Tails) please explain why this would be a duplicate???

The block the button is placed on BUD-powers the dispensers diagonally (MC-108), this is where MC-11193 comes into place.
