i have just installed some spot lights in my bathroom, i want them to work independently from the shower light/fan. Obviously i can not use a normal light switch in a bathroom so i wanted to share the live feed from the landing light which is on the same wall. The landing light has just the 1 switch so i thought i could replace that with one that has 2 switches. would this be ok and how do i wire it up when i get the 2 switch switch. sorry if i have confused you
