Switching out lighting and outlets in our 1981 home from wonderful khaki to something more modern. I've done 3-way and 4-way switches, outlets, GFCI, etc. all over the house, but the bathrooms have run me into a small issue. I've just encountered what I now now to be Despard switches for the light/heat/fan in the guest bathroom. Each switch has a pair of black wires coming in; the left-hand side trio that is all pig-tailed into one original wire is hot, and the three right-hand side ones are not hot. How would I go about switching this over to the more standard 3-rocker switch seen below? Everyone is 15 Amp.
This is actually really easy. The typical triple Decora rocker switch, such as this Leviton from Home Depot:
has one common input and three switched outputs. You actually get rid of the 3 pigtails and connect the hot wire to the common screw and the three switched hots to the three screws on the other side.
If you had three separate circuits, instead of three devices on one circuit, then this would be a real problem. You've got it easy.
