Hi, probably a little eccentric an idea but I have bought a 24 hour timer switch (live and neutral supply and load) to control a fluorescent tube light. I was going to mount it above the light switch which would be still in use. I KNOW THAT A LIGHTS WITCH DOESN'T HAVE A NEUTRAL. Can I still use the old lights with and timer ( which has a permanent "on" function.) to control the light when the house is unoccupied ? A wiring diagram would be appreciated if possible. Thanks for any help.
