Can someone explain to me why there are three red wires in the original switch picture, when there are only 2 lights in the kitchen? And why is there the cross over wire also? And if the new dimmable LED switch is the right replacement for the original switch.
(As ericmark said, there have been forum problems) The reason you have 3 red wires at your switch is because one, is the live supply (It is the one that links to the other switch in order to give a "2nd supply") The other two reds are the ones that go to each light. They are known as switch wires, because when you operate the switch, they become live.
As for will your new switch work with your existing lights, that depends on the actual lamps, can they be dimmed, and do they meet the requirements of the dimmer?
As for connections, ericmark has already answered that one.
