Dear Mark,
We have some PDF drawings on the Comfort site with the hook-up diagrams
for 2-way and intermediate, if they are of use.

> Now, please don't laugh, and don't say X-10, but can anyone remind me
how
to wire a three-way-switchable light.
>
> I can do a one-way or a two-way so that whichever switch is thrown,
then
the light "changes state", and I remember seeing a wonderfully
elegant
design that did three-way, but I can't remember how....

> A one way is:
>
>      / ----b
>     /
> a---S1
>     \
>      \
>
> If S1 is set so that a and b are connected, then the light comes on.
> If S1 is set so that a and b are not connected, then the light goes
off.

> A two way is:
>
>     /--------\
>    /          \
> a-- s1      s2 --b
>    \          /
>     \--------/

> If S1 and S2 are set so that a and b are connected, the light comes
on.
> - This happens if S1 is set to the upper position AND S2 is set to the
upper position
> - This happens if S1 is set to the lower position AND S2 is set to the
lower position
> If S1 and S2 are set so that a and b are not connected, then the light
goes off.

lower position
