I'm having a bit of a problem wiring a new light. I changed 2 light fittings which I believe are on a Loop. They both work, the problem is the Switch on the light which holds all the loops wires. It has 2 reds, 2 blacks a blue and a brown. I stupidly didn't make a note of what went where before I disconnected the old light. I put the 2 reds together, One Black, and one Brown with the light flex Brown & One black and the Blue with the Flex Blue. The light stays on constantly when I switch the power back on. I assume I have managed not to route/loop the live flow through the switch and I do not know what to do. I'm not sure which Black is the Switch Black as it wasn't marked. If there is anyone who I could help I would be very greatful!!!
