The RUST XOR Switch is a deployable electrical gateway (trigger) device that allows for electrical current passthrough from one of two different sources so long as only one is transferring power at a time.
While using a Wire Tool to check available ports, players will find the standard Power Out and as well as Input A and Input B. You can think of XOR switches as if they were spelling out the word ‘or’, in that it functions only if A or B is powered. If both sides are powered, no power passthrough is allowed, essentially the same as if you turn a Switch would off.
XOR switches are found in an assortment of low-to-mid-tier crates, as well as dropped from many scientist types. RUST players may learn them directly or through a Scrap investment into the Tier 1 Workbench tech tree.
