Knightsbridge 8300MB 2 Way Pull Cord Light Switch in Matt Black, 36.0 mm*74.0 mm*74.0 mm
About this deal
Use a small flathead screwdriver to undo tightening screws and pull the wires out. Then unscrew the base unit which is mounted to the ceiling and remove the old unit. Now you are ready to install your new pull cord switch. Before you start make sure you isolate the electrical supply before attempting to replace the switch. You will typically find your fuse board or MCB panel and trip the fuse which controls all the lights.
Took of bottom half of pull cord bathroom switch. Only 2 wires both brown came out when I took bottom off. Do I need to know which cable goes in where? Or is it just a case of 1 in com and another in L1 or L2 I.e. is there a difference in these 2 wires? Before you disconnect any wires always test the wires and make sure that they are not live – you don’t know who installed it and if it’s installed properly so it’s better to be safe than sorry.Undo the screws on your new switch where the wires will go – feed the main cable through the base and screw the base into the ceiling. Now you can connect the wires – just make sure you tighten the screws properly and if the earth wire is present that you put a sleeve on it and connect it to its place on the base plate. As you can see in this picture whoever installed it they never bothered connecting the earth to its place for some reason.
