I put in some recessed lighting a year ago and to put it simply I took the easy way out and found a switch that operated 3 sets of lights but only took the space of one switch. Would really like to put them on a dimmer, and once again would like to go down the easy path and not have to cut out the gang box to install something bigger....Do they make a dimmer switch that would operate 3 different sets of lights similar to the picture I will post below with my switch? The alone switch to the right operates a wall outlet in case anyone wanted to know. [ATTACH]71359[/ATTACH]
