A metal light switch must be earthed as seen below. To add a second light which is switched with the first one the switched line neutral and earth need to be extended to the second light.
Multiple Lights From A Single Switch
How to wire two lights to one switch uk. Lighting circuits are easy to wire. To wire your two way switches firstly tag the neutral blue wire of the switch cable and the black and the grey of the link cable at both ends with brown sleeving to mark them out as being live. To wire this circuit in this manner you will need to run a 143 between the two light boxes. Please helpi have changed from a single light switch to a double switch to use on 2 seperate lightsthe double switch has coml1l2top and bottomthe wires i have are 2red2blue2earthhow do i wire these up. This diagram shows the additional cable connected to an existing ceiling rose. Run your cable from the first light to the second light.
It is one black wire from the power source hot wire and a black wire from the neighboring switch. Connect the black fixture wires together and connect the white fixture wires together to form the parallel circuit. The other end of this cable is taken to the position of the new light. Essentially 2 black wires are attached to the bottom dark screw of one switch. Wrap a piece of black electrical tape around each end of this white wire to indicate that it is a hot wire rather than a neutral wire. So what i am doing is adding an extra lightthank you.
The l2 terminal is unused. Connect the one black wire to the bottom dark screw of the other already wire configured switch. Return wire from switch into switched connection of first light to make light work along with live conductor in the link cable supplying the second light if its a standard rose style fitting the mains supply at second light can simply be terminated in the loop live neutral and earth connections 0 m4tty. The neutral bluebrown of the switch cable connects to the l1 terminal on the switch. Connect the black wire from the switch to the black wire from the first light and the black wire coming from the second light. To control two lights with one switch wire the lights in parallel.
The easiest way to connect multiple lights to one switch is to daisy chain the lights which means to connect them together and attach just one of the lights to the switch. A two way light switch can also be used in in place of a one way light switch in this instance the red wire from the feed cable is connected to the common c terminal and the red wire going to the light is connected to the l1 terminal. This will allow you to connect the first light as you described above and to run this additional light from the same switch by utilizing the red conductor in the 3 wire as the switched conductor and the black wire as the continuous hot wire. The new cable here is labelled light 2. You can also do a home run configuration by feeding all the cables to the switch and connecting them with a pigtail.
