I wanted to fit a dimmer at one end of a 3way circuit (3 switches control the same light - currently 2x 2 way & 1x intermediate) in my hall and stairs, but is there a way of doing it so that the lights can be dimmed from all points rather than a dimmer on just one point? Just thinking, could be dangerous if dimmed right down and you're at the non dimmer switch end of the hall in the dark!
