I would like to have light dimmers and also be able to control from two places in a room. I believe if I simply wire two in parallel then the one set to the highest level will "win". I want either to have total control. I remember there were some light dimmer types that could also be pressed like a switch. Is it possible to have two light dimmers and be able to use either to control the lights, by means of pressing the button and making it "master" ?
