I am in the process of changing light switches in my house, the double switch in the hall controls a single switch and light at the top of the stairs and the light in the hall. When removing the cover I find the new switch is not the same as the old. The old cover has L1, L2, and Comm at the top, and the same at the bottom. The new cover has 2 Comms at the top and L1 and L2 twice at the bottom. The Wiring is Yellow, Red and Blue from 1 cable and 2 Red wires from the other cable. Which wires do I attach to which terminals.
