I am replacing a 2 gang light swich in the kitchen with a dimmer switch. When I opened the switch plate to replace it with the new one, I thought all I had to do was replace the existing wires into the new switch, but when I opened the switch thinking I would find 2 red wires and 2 black wires so I would know what was live and what was neutral, what I found was all 4 wires going into the switch was red, 2 into the top and 2 going into the bottom with a red wire connecting the bottom 2. I think the bottom connections must be the live do not want to do anything withouy advise. any comments on this would be helpfull. thanks in advance. jim bob
