switching a light

I have a series of three highhats feeding off a three-way dimmer switch. Naturally I have a B and a W lead coming in from the second fixture to the last fixture. I want to add a switch between the second and last fixtures so that that last fixture can be turned on or off (or dimmed) either from the three-way switch (with the others) and can be turned off independently of the others in the series.

I would guess all I have to do is break the B lead between the second and third fixtures with a regular single-pole switch and run the W through to the third fixture.

Is that right? Or am I missing something.

 

Yep,, just make the connects in one of the boxes so they are enclosed and you all set to go.

 

A lot depends on how independent you mean by "independently". There will be no way to have the last light on without also having the other lights on. And if the three-way switches include a dimmer, that dimmer will affect the last light too. If all of this is okay, then you're good to go. Of course, this is unusual and most people other than you will have a hard time figuring out how to work the switches.

 

Thanks! I all set.

This situation is a bit unique. There's three separate groups of lights in the room. Each on it's own 3-way with a dimmer on one end.

The group in question has one fixture that instead of being in the ceiling field, is in a small alcove leading to a bathroom door. It doesn't need to be on 99% of the time but there may be that 1% where we will want the light. If it is dimmed along with the others... no problem.

It's just that it was easier (less wiring) to feed this light off the existing lights rather than put it on its own circuit.
