I heard some contractors hooking up three 3-way switches instead of a four
way. How is that wired? I always use a four way, but I think it is done
for cost reasons.
I remember an article, in a 1960 vintage homeowner's encyclopedia, that
showed
how to wire _two_ three-way switches to work as a four-way switch. The
handles
were ganged by runnning a screw through them to make the switches
operate
together. Electrically, you have same thing, but I don't think it really
meets
code.
What the contractors may have been talking about is rearranging a
lighting
circuit with three or more switches into several circuits with only two
switches on each one. Why they might need or want to, I have no idea.
