@jacksonmj This works well, really interesting way to use wire (i dont understand this element, haven't seen any use for this until now...) but even using wire, you need at least a space of 7x17px to use this. I was thinking about an element that could do this in 1x1px. My idea is something like a switch, that would switch if PSCN or NSCN charge it, different from SWCH, that charges only with PSCN. Then, Energy would be able to pass through this element only if the conductor is METL, INST, INWR, something like that.
