i want to wire a light switch for six 50 watt downlighters. The cable from the fuse box will only be used for this purpose. I am not sure how to wire the light switch. Am i right in having the cable going from the fuse box to the lightswitch and then a cable going from the lightswitch to the lights (the downlighters in series)? The cable has a brown, blue and bare earth wire. So there are 6 wires in all that go into the light switch. The light switch has a hole for common and a hole saying one-way. Where does each wire go?
