... The way I was hoping the wiring to be was that all four of the switches were on the same line leading to the light. But, the way I believe it to be is that the first two switches (the ones I wired first) are on one side and the second two switches are on the other side of the light, with the light being in the middle. I saw a diagram of this on a website listing different 4 way switch diagrams. My question is this: how can I wire the last two companion switches to work? Or is there something else that I have to do to get everything to work correctly? I will answer any questions in the best way I possibly can. Any help will be appreciated. Thanks!
3ric,
Electrically speaking, the lamp can't be wired in the middle of your switch circuit. There are many ways of bringing power into the switch circuit and different ways of routing the wires. This is what many of the Web resources are trying to describe (power entering through the light fixture, etc.). These are practical considerations when performing the initial wiring of the circuit.
While the practical diagram deal with wire routing, number of conductors and such, the electrical diagram for the circuit is far simpler. Your mechanical switch installation should comply with circuit #3 in the attached regardless of where power enters your installation.
Rules for multiway mechanical switch installs:
- Unswitched power (from your electrical panel) will connect to one of the 3-way switches
- Switched power will be delivered to the load from the second 3-way switch.
Hopefully this will allow you to draw a diagram of your original installation. With that in hand, you should be able to determine the problem with your WS4777 install.
As
Oldtimer was indicating, you'll need a meter to determine which 3way is receiving uninterrupted power from your electrical panel. The second 3way will then be the switch delivering power to the lamp.
When installing the WS4777 and slaves you will may need to "re-identify" some of the existing traveler wires. If you find yourself needing to use a white (neutral) wire for a hot connection, re-identify it with a marker or appropriate color electrical tape.
