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, try Googling the search terms "3-way switch" or "4-way switch."
Using KeypadLinc in Virtual Multi-Way Circuits
By creating virtual, multi-way circuits, you can use KeypadLincs to replace switches in 3-way, 4-way and
higher multi-way circuits that are already wired into your home. Or, you can use them to create multi-way
circuits where there is no existing, multi-way wiring thus saving the hassle and expense of re-wiring.
In a virtual multi-way circuit, only one KeypadLinc, called the KeypadLinc Primary, actually connects to
the load in the multi-way circuit. Additional KeypadLincs, called KeypadLinc Secondaries, are not
connected to the load, but only to power (LINE and NEUTRAL wires). All of the KeypadLincs
communicate with the others using INSTEON. After wiring in the KeypadLincs, you can create the virtual
multi-way circuit by setting up all of the KeypadLincs (or KeypadLinc and switches) to control each other
(see Control Groups
). The diagram below shows a previously wired 3-way circuit, now a virtual 3-way
circuit using a KeypadLinc plus other INSTEON switch or keypad.
