A wired-in 4- or more-way circuit (with three or more switches) has additional switches added in the
middle of the circuit. In the diagram below, the additional switch (Switch 3+) is shown in two different
positions, since wiring can vary from home to home.
To learn more about multi-way circuits, go to your preferred Internet search engine and enter the search
terms “3-way switch” or “4-way switch.”
Using SwitchLinc in Virtual Multi-Way Circuits
You can use SwitchLinc modules to replace switches in multi-way circuits that are already wired in or to
create multi-way circuits where there is no existing wiring. These are called virtual multi-way circuits.
In a virtual multi-way circuit, only one SwitchLinc (called SwitchLinc Primary) is actually connected to and
controls the load. Any additional SwitchLinc modules (called SwitchLinc Secondaries) are only connected
to the powerline via the line and neutral wires. All SwitchLinc modules can communicate with one another
using INSTEON networking on the powerline. After wiring in SwitchLinc modules, you can create a virtual
multi-way circuit by setting up all of the modules to control each other. The diagram below shows how you
convert a wired-in 3-way circuit using two SwitchLinc modules.
Note: Actual location of SwitchLinc wires may differ with product revision or model.
