Electronic switch to re-purpose dead end 3-way?

[wwhitney]

It occurs to me that if the goal is to have neutral and switched hot at box B, then you could still do that with a relay at box A, if it's legitimate to switch the neutral on the relay coil circuit. I know that for utilization equipment you have to switch the ungrounded conductor, but for a control device like a relay, is switching the grounded conductor allowed?

You guys are awesome thanks for all the replies!

You could use a Lutron Maestro C-L/LED+ dimmer at the main switch location, and have a mechanical switch at the present dead-end location (as shown below and on pg. 4 of the document at the link below). In this configuration the switched/dimmed hot is available for having lights at both locations with only a 3-wire connection between them. This mode will have to be programmed into the dimmer with its buttons.

Thanks Syncro this is it.

Actually synchro’s post #9 would work because it wouldn’t need a switched leg returning from the second switch. It can be tapped into at switch one before it leaves.

The x-10 works too but it warns against using led unless that’s a different application and Insteon works but it’s not physically wired to switch 2.

Now that you mention it, his and my diagrams are actually the same.
