3 way switch wiring

Question

Hello Vandwellers!

I'm trying to wire 2 zones of LEDs in my build and I'm curious on the wire lengths required when switching the zones with 3 way switches.

The plan is: Distribution Panel -> 2 zone dimmer -> Bed Switch (3 way) -> Side door switch (travellers) -> Light strings

Can I just run the positive wire through the 3 way switching part and run the negative from the Dimmer straight up to the lights. Would save me a bunch of wire but the negative length would be ~10 ft shorter than the positive.

Thanks!

To save on wire, I got a RF-controlled relay instead: https://www.amazon.com/dp/B081TWRYG6/ref=cm_sw_r_cp_apip_2nDhCZq3Dx6rl

I had a similar thought process to your idea, and (coming from AC experience) I was thinking I needed the neutral running with the travelers. Oops, did I just say neutral? See?

Anyhow, my mind was on inductance, which I guess isn’t really a DC thing.

So there you have it. Not really any kind of answer, and the ramblings of a madman. Nice to meet you!

That's a nifty little product you linked! Is that mounted behind your walls/ceiling and you have A on one zone and B on another?

Yup, nailed it. I have mine tucked in one of the vertical sections beside my back doors. I keep one key fob beside my bed, and I had intended to hang the other at my side door, but I actually prefer keeping that one in my pocket.
