With help from you guy's, I have now wired in correctly a 2gang dimmer in my hallway and have left a single gang switch upstairs. All works a predicted exept, when I turn off the landing light upstairs, if I try to turn them on from the downstairs dimmer they won't ! The dimmer is push on / off type. Do I need a special dimmer or a special upstairs switch.
p.s. The reason for the dimmer is an under estimation of the power of ceiling spots i.e. to many !
