Hi, please help if you can! I have a double, one way switch for a hall light and a porch light. The old switch has: top, L1, L2 and Common with a red cable going into L2 and another red cable into Common. There is a bridging red cable going from top common into bottom common and a grey wire going into the bottom L2. There is nothing in either top or bottom L1. The new switch has two separate black terminals boxes, each one has an L at the top and and L1 and L2 at the bottom.
Not sure what goes where on this new switch!
