Hello all. I'm trying to install a new dual switch in my bathroom so I can dim the lights with one but be able to just have an on/off switch for the fan. I've attached a picture to try and make things a little easier to explain. If you look at the picture I attached, my current switch and wiring(in very simple form) is the one on the left. I'm trying to replace this switch with the one shown on the right. I thought it would basically be a direct swap, but there are fewer terminals on the new switch so I'm not exactly sure how to go about doing this. Do I connect the wires connected to the brass terminals(circled in red) to the brass terminals on the new switch? Do the black wires go to the black terminal on the new switch(circled in blue)? Should I just use one of the black wires and cap off the other one, or should I pigtail them together and them wire it to the black terminal? Any help with this is greatly appreciated! Thanks!

I have a 12V, 1A transformer I would like to use. I have a resistance wire of 25 Ohm / meter (8.3 Ohm / foot). To use this cable I need 48 centimeters (18.9"). This is too long, but is it possible to go 24 centimeters up and 24 centimeters back with the wire to obtain the same length? If I cut two pieces of 24 and attach them both to electricity I think my resistance changes, no? This is not usable? If the wires would touch eachother, would that change the resistance? I have a picture below: [URL=https://imageshack.com/i/0ojq1wp][IMG]http://imagizer.imageshack.us/v2/800x600q90/24/jq1w.png[/IMG][/URL] Hope someone can help me! Thomas
