I need to put an additional light on an outbuilding, the building already has a switchable internal light but I want to add a permanently on (dusk til dawn sensor) light to the exterior. I thought to use the same supply as the interior light but just add a twin switch so that the interior can be turned off but the supply to the exterior remains intact. The single switch is simple connections for load and supply designated with L,N and earth. However the twin switch I bought has the two switches designated each with Common and L1,L2. How do I connect this with the supply and the feed to the two light units?
Thanks
