Along with this, we need a more spacious switchbox. Boxes already get crowded and an extra wire often gets a 1g box over the limit. I'd hate to go back to the old way of power to lights, switch legs down. That lets the light box hold more of the splices and the in/out hots but also means taking down lights with any future troubleshooting. But feed in/feed out, 14-2-2 to 1 switch, 14-2-2 to another, makes 13 wires in light box, 5 in each switchbox, 2 for device makes 7. If a 4 way needed, 14-3 switch to switch would increase 3w sw's to 10, 4w sw would be 9.
I have seen a through the wall switchbox that would be great for back to back switches. I don't recall volume or capacity but would have to be pretty good. Of course, not all switches can be back to back.
A standard size box with the side pocket would be good too, similar to the blue Carlon shallow ones sold at Lowe's & HD. I use them for mobile homes occasionally.
4" deep boxes with mud rings could be used but are costly and time consuming.
BTW, has anyone seen a 4 way switch with dimmer or motion sensor? I don't recall seeing them anywhere.
