About this deal

Standard cord switches are usually white. There is often a handle at the end of the cord to enable you to pull the cord downwards easily. The electronic part of the switch sits within a plastic housing which fixes to the ceiling by screws. One thing to note however is that the switches do differ slightly. Whereas the 6 amp switch is single pole, the 45 amp switch will be double pole as it needs to be able to isolate both the live and neutral.

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. Adding additional lighting, light fittings and switches, to an existing circuit – As long as not in a kitchen or bathroom All this is conditional upon the use of suitable cable and fittings for the application, that the circuit protective measures are unaffected and suitable for protecting the new circuit and that all work complies with all other appropriate regulations. As stated, in the majority of cases they are used in areas subject to water and moisture as the fact that you have a pull cord to turn the light or appliance on and off you are no where near any electrical internals that could easily have water splashed onto them causing serious electrical injury. Step 3 – Spray the switch area with the a little maintenance spray or WD40 and attempt to loosen the spring to make the switch work properly. Hold it with one hand and pull the cord with the other

You can only compare up to four products at a time.

Step 4 – Supporting the switch with one hand, try to operate the pull cord with the other hand to see if the maintenance spray has freed up the spring and therefore the switch should work properly again Step 1 – Firstly isolate the power to the circuit you are working on in your consumer unit by turning off the MCB for that circuit or if a fuse box, pulling out the fuse. If you are unsure which is which, turn off all the power using the main isolator switch For the first part of this guide we will work through replacing a standard 6 amp pull cord light switch. From step 6 we will explain changing a 45 amp isolation switch. Step 1 – Isolate the Switch and Circuit If this is ignored then you may face problems when trying to sell your property as if its had notifiable electrical work carried out, but for which the appropriate certificate from a qualified electrician cannot be produced. Additionally, it will also propably invalidate your home insurance.

Step 2 – Undo the two retaining screws holding the switch in place and carefully pull it down a little. There should be sufficient wiring to allow you to do this as with the lighter duty switch above

1-Way vs. 2-Way Pull Cord Switches

Again, if this has does not work, the whole unit must be replaced. Replacing the Cord From a Pull Cord Switch Step 3 – Using some maintenance spray such as WD40, apply the lubricant to the inside of the switch, where the wires are connected, especially in around the pull cord section Step 1 – Before doing anything, turn off the circuit you are working on in the consumer unit or fuse box by turning off the MCB or pulling out the fuse. Most of these types of switch include a neon indicator, which will glow red or orange. If you have switched off the supply correctly the indicator will not be lit.
