Dear Dale:
I am quite sure we are talking about different situations. The 4 way
switch arrangement I am referring to, involves one light and three switches,
each of which can turn the light on or off. I have such a situation with
regard to my entry hall lights. I have a switch just inside the exterior door,
which is in the center of the hallway, with switches at either end, which
allows a person coming in to the hallway from the kitchen end or the bedroom
end to turn the lights on or off.
A 3 way switch is used in tandem so that the user can turn the light on or
off from two locations. As you know, one can series several lights so that one
switch controls all of them, such as in my hallway, where we have three
recessed lights. My first wife picked them, and am I glad, because she has
griped for thirty-three years about how little light these can lights produce.
Yours Truly,
Clifford Wilson
