How to distance between for switch and base level?
I don't think I understand the question. If you mean how high off the floor you install a switch, it is at what ever height you want it. In a residence that is normally about 48". Emphasizing "about"

Hank,

I've always the boxes 48" to center of box from the finished floor. Does that qualify as "About" for you? :)

Good 'nough for who its for Don.
