There is a wall fixture with a pull chain in my powder room. Adding a
switch leg to it would be a real bear because of the wall construction, so I
have been putting the project off. (I put a three way switch elsewhere in
the wall and it took me a full day; don't ask.)
Today I saw a pair of RF switches at the hardware store for half price
($12.50); they are intended to change a single switch to a pair of 3way
switchs without any wiring.
I have access to the wire before it goes into the wall for the light and
there is a lot of slack. I could cut it, put in a box with the wired
switch, and then just put the second switch where I want it. I would just
ignore the wired switch and use the RF switch for the light.
Aside from the cost of those AAA batteries, am I overlooking any obvious
problems with this scheme?
