na klar...
sorry it took a while for me to get this posted but here it is, its quite a simple drawing, but i hope it makes sense.
**broken link removed**
the latching relay should switch in the absense of current, and it does, but not regularly. the pause is just too short.
the solution i seek would be to have a reliable system where the light is turned on and off by a normal looking wall switch but the other stuff is not effected.
Kmoffett: this relay would work? i don#t see how it solves the problem, is it so fast switching?
eblc: the relay you mentioned sounds like a good solution, how much does something like that cost?
Remote controls are an option, but one i would rather avoid, for cost and lost remotes, battery changes..
