The Blocker is a RUST electrical component that is highly useful.
Its primary function is to block electricity traveling through the unit’s mainline if the socket on its side also receives electricity.
The blocker has two inputs and one output that players can wire into if they have a Wire Tool on their Hotbar.
By running electricity through the input socket on the bottom of the blocker and the output socket on top of the blocker, the player creates a main electrical line that can shut off when necessary.
When electrical power feeds into the input on the side, the mainline will stop providing electricity through the blocker’s top output socket.
As the blocker stops electricity if the side input is powered, the electrical feed for the side input cannot come from the top output of the blocker.
Doing so will result in the blocker trying to block itself and will short out the circuit.
A typical use for the blocker would be to run a sensor’s output into the side input circuit so that power shuts off to services you do not want unfamiliar players to access.
E.g., Closing doors or shutting down electrical components.
The blocker has poor health, so if you are wiring your base, keep the blocker on an interior wall to prevent players from easily destroying it.
