Replacing a ceiling fan pull switch. Thread starter ElectroGeeza Start date Aug 28, Status Not open for further replies. ElectroGeeza New Member. Hey all! I need to repair a ceiling fan. It is a combined 5 bulb light fixture with a 3 speed fan.
There is one pull switch for the light and one for the fan.How to go about wiring a shower or bathroom light pull cord switch. Advice on fitting a pull cord switch, replacing a pull cord switch or replacing the cord. Due to the nature of pull cord switches, they can wear out quite fast. In this DIY guide we will show you how to repair a bathroom light pull cord switch or 45amp shower pull cord switch.
You will also learn how to replace a bathroom light or shower pull cord switch, how to replace the actual cord and also you will find out about what electrical work you are allowed to do in your home.

A pull cord switch is typically mounted to the ceiling, with the pull cord hanging down, most often used in a bathroom or toilet and generally available in two types and ratings:.
After some use and time this type of switch can get a little tired where the switch appears not to function properly as an internal spring can get stuck. The 6 amp switch is usually part of the lighting circuit and is fused in the main distribution unit.
It is very important to isolate the electrical supply before attempting any repair to the switch. Undo the two screws securing the switch to the back plate and using some maintenance spray such as WD40, apply the lubricant to the inside of the switch, where the wires are connected.
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. If this does not work, then the switch must be replaced see Replacing the switch section below. With the heavier duty 45 amp pull switch, the spring is usually much stronger and an audible click will be apparent when operating this type of switch.
Occasionally these switches can break down and again, before attempting to work on the switch, you must isolate the electrical supply. Look for a fuse or circuit breaker on the main distribution board marked shower and either remove the fuse or trip the breaker MCB. 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. Undo the two retaining screws, carefully pull down the switch a little. There should be sufficient wiring to allow you to do this and as with the lighter duty switch, spray with the Maintenance spray and attempt to make the switch work properly.
If this has not worked, the whole unit must be replaced. Ensure the electricity is isolated from the switch by following the instructions mentioned above. Either remove a fuse or trip the breaker MCB. With the 6 amp switch for lighting, there are usually just two wires to disconnect.
It is possible that these will be the same colour, either red or in newer wiring circuits, you may find brown or black or even blue. Usually a small flat blade screwdriver is necessary to undo the tightening screws and pull the wires free.
To avoid fatigue and whilst on a stepladder, it is normally best to slightly undo the tightening screws of the new unit before attempting to connect the wiring to the new switch. Connect each wire in turn, tightening the screws and then gently try to pull the wire from each side of the switch, to ensure you have connected it properly. Then making sure you do not kink or trap the wiring, fit the switch to the backing plate and operate the pull cord to check it is functioning properly. Replacing the 45 amp isolator switch follows the same principle as the 6 amp version, however the switches can differ as single pole, i.
Note the wiring positions and cut off the electrical supply. A more substantial screwdriver is normally required and note that the wiring thickness will be usually 4mm2, 6mm2 or even 10mm2 and therefore these wires are a lot stiffer than wiring used for lighting.Enter your email address to subscribe to this blog and receive notifications of new posts by email.
Sign me up! Wiring diagram of a one way lighting circuit using junction boxes fig 1. Explanation of above picture. The black wire from the light switch, should be marked with red sleeving to show it is a live wire, but in practice is often left unmarked if you come across this it is good practice to sleeve the switch wire. The red wire going to the ceiling rose is connected to the same terminal as the black wire marked with red sleeving coming from the light switch, the black wire going to the ceiling rose is connected to the same terminal as the black wire from the feed cable and the earth wire is connected to the same terminal as the earth wire from the feed cable.
The following picture is exactly the same as the picture above with the addition of another cable which provides the feed for the next junction box. The red wire going to the next junction box is connected to the same terminal as the red wire from the feed cable, the black wire going to the next junction box is connected to the same terminal as the black wire from the feed cable and the earth wire going to the next junction box is connected to the same terminal as the earth wire from the feed cable.
The red wire is connected to L1 or in this case the top terminal, the black wire is connected to the common or in this case the bottom terminal and the earth wire is connected to the earth terminal. If you are using a plastic switch the earth wire will need to be connected to the terminal in the terminal box as shown above because there are no earth terminals on plastic switches.
A two way light switch can also be used in in place of a one way light switch, in this instance the red wire is connected to the common C terminal and the black wire is connected to the L1 terminal. The L2 terminal is unused.
Switched Plug Wiring Diagram
If you are using metal light switches fig 5 make sure you connect the earth wire to the earth terminal on the switch and fit an earth link wire from the switch to the earth terminal in the back box. When using a ceiling rose on a circuit that utilises junction boxes, again the wiring is quite easy, the difficult part is working at height and above your head. The red wire is connected to the same terminal block that contains the brown wire going to the lampholder, the black wire is connected to the same terminal block that contains the blue wire going to the lampholder and the earth wire is connected to the earth terminal.

This page contains wiring diagrams for household light switches and includes: a switch loop, single-pole switches, light dimmer, and a few choices for wiring a outlet switch combo device.
Also included are wiring arrangements for multiple light fixtures controlled by one switch, two switches on one box, and a split receptacle controlled by two switches. When the electrical source originates at a light fixture and is controlled from a remote location, a switch loop is used. This circuit is wired with a 2-wire cable running from the light to the switch location. The neutral from the source is connected directly to the neutral terminal on the light and the source hot is spliced with the white loop wire.
The white wire is marked black on both ends to identify it as hot. At SW1 it is connected to one of the terminals. The black loop wire is connected to the other terminal and at the light, to the hot terminal on the fixture. This is an updated version of the first arrangement. Because the electrical code as of the NEC update requires a neutral wire in most new switch boxes, a 3-wire cable runs between the light and switch.
The red and black are used for hot and the white neutral wire at the switch box allows for powering a timer, remote control, or other programmable switch. Here a single-pole switch controls the power to a light fixture.
The source is at the switch and 2-wire cable runs from there to the light. The source hot wire is connected to a switch terminal and the other terminal is connected to the black cable wire. The neutral wire from the source is spliced to the white cable wire and continues on to the light. At the light, the white wire connects to the neutral terminal and the black wire connects to the hot. Here two switches are wired in the same box to control two separate lights.
The source is at the switch box and a 2-wire cable is run to each light. One source is spliced to each switch with a pigtail to power the two lights.
This diagram illustrates wiring for one switch to control 2 or more lights. The source is at SW1 and 2-wire cable runs from there to the fixtures. The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light.
This is the simplest arrangement for more than one light on a single switch. A rheostat, or dimmer, makes it possible to vary the current flowing to a light fixture thereby varying the intensity of the light. The dimmer switch will have stranded wires that must be sliced to the solid cable wiring in a pigtail fashion.
A device like this should only be used with an incandescent light fixture and not with a ceiling fan or other motor. See wiring a speed controller for wiring a rheostat to control fan speed.
To wire this circuit, 2-wire cable runs from the dimmer to the light.Ceiling Light Fixture Electrical Wiring and Connections: Depending on the age of the home there may be one or more cables found in the ceiling junction box. These cables are used for distributing power to the light fixture, the wall switch, and may provide power to wall receptacle outlets as well.
Application: Wiring a Ceiling Light Fixture. Estimated Time: Depends on personal level experience, ability to work with tools and access to the light fixture. Notice: Installing additional fixture wiring should be done according to local and national electrical codes with a permit and be inspected.
Depending on the age of the home there may be one or more cables found in the ceiling junction box. NOTE: The preceding may not reflect each and every wiring scenario in the same locations. I have provided the following resources that lead to fully detailed information on this website that will assist you with your Light Fixture Electrical Wiring: Light Switch Wiring.
Fully explained pictures and wiring diagrams about wiring light switches describing the most common switches starting with photo diagram 1. Electrical Wiring Home electrical wiring projects with pictures and wiring diagrams. Electrical Codes for Wiring. I have a ceiling fan and a light fixture in the added-on front enclosed porch. There is a light with a pull chain at the end of the run, then a ceiling fan — all connected with wire mold — then an antiquated five speed rheostat at the dead end of the run.
The switch inside the front door controls the power to the porch system. I am replacing the fan control with a new 3A 3 speed controller and I need to add an outlet to this system on the porch. There were two wires white and Black connected to the old rheostat, from the Wiremold — white to white, black to black.
How where do I add the receptacle which will also have juice when the interior light switch is turned on while allowing the fan and pull chain light to also operate independently also, only when the interior switch is on. Thank you. I have tried to figure this out and keep getting confused. Hi Andy, Before adding an outlet to a switch box the circuit wiring at the switch box will need to be verified to make sure there is a separate neutral and ground wire as well as the power source, all of which are required for an outlet.
This is best discovered by using a voltage tester. I hope this helps, Dave. Hi there, I was changing an old ceiling light fixture with a new one. Removing the old fixture I discovered 3 black wire, 3 white wires and a ground.
I connected black to black, white to white with the new fixture that had one white, one black and one ground. If this is so, how do I find it?? Is there a black to white connection for the switch? Any advise you could give me would be appreciated. Thank you, Cavell.
I hired a general contractor to do some painting and to also install a light fixture from my 2-story ceiling. Now that the job is done, I noticed that the ground wire for the fixture is tied off to the chain links below ceiling height rather than run up through the ceiling plate of the light.
Not a very professional job in my opinion.The one in my bathroom started playing up so I replaced it never to miss an opertunity I took it appart to see what was inside. The switch plate is secured by 2 screws the mechanism by a further two the mounting case holds just an earthing terminal. The first thing I discoverd was that after removing the switch plate and shaking out some plaster granules vigorously operating the switch freed it off, but having already purchased a replacement I changed it anyway.
The mechanism is spring loaded so it is vital you hold the parts together as you release the securing screws once removed gently release the pressure and remove the back plate at this point the screw terminals and fixed contacts will fall out.
The rest of the components as they come off the cord. The carrier plate and moving cams, a small spring and finally the cord termination. My problem appears to have been that plaster dust managed to get inside the mechanism during 30 odd years of use and fouled the mechanisum a simple clean was all it needed. This switch is a basic 2 pole on off switch and only rated at 6Amps externally it looks very much like a 16amp rated power switch intended for switching immersion heaters showers etc.
Should someone have inadvertently used a light switch for power it might be possible to clean and refurbished the contacts I'd only considered this as an emergency measure. It really is just the reverse of dismantling.
Replacing Bathroom Pullcord Switch - Wiring help!
Set the fixed contacts into the back plate and set aside. If changing the cord start by tying either a figure 8 or reef knot feed the long end through the cord terminator make sure the knot is fully contained in the terminator and trim the tail off if required. Then refit the screws holding the two plates together. The best way to do this is insert a screw in its hole. Apply just enough pressure with the screw driver to hold it in the head of the screw and turn it very gently anti clockwise that is as if you are undoing it until you feel the screw suddenly drop a fraction it has just engaged with the old thread in the swich plate now turn it clockwise and it up tight, repeat with the other srew.
Understanding Electrical Wiring for Ceiling Light Fixtures
As these fixing screws are course self tappers you could just stick them in the hole and do them up, they might find the old thread if you did that but would most likely cut a new one and if removed several times you would quickly have a hole in the switch plate that the screws could not grip in.
You can now test your rebuilt switch either with a continuity meter or a simple low voltage battery and bulb. If you can't fix your switch there are some salvageable bits. The cup and plain washer make a good low load thrust bearing. The fixed and moving contacts have potential to be reused in other places as electrical contacts. The fixed ones being solid brass could also be used as low speed shaft bearings. Tip 10 months ago on Step 1. Could the way the switch is made cause any fire if badly assembling it looking at the circumstances?
