Light switch is a device which is used to operate electric lights. It can be of permanent or temporary arrangement based on your needs. Light switches in some case even could be hand-held devices. Residential and commercial buildings usually have permanently wall mounted light switches depending on factors like mounting height and visibility. These switches may encounter several technical issues while in use. While sometimes, wrong electrical wiring can lead to the failure of a light switch, sometimes even the fault may be with the switch itself. The first light switch employing quick-break technology was invented by John Henry Holmes in 1884 in the Shield field district of Newcastle. You may face some issues while troubleshooting an electrical light switch. So, read on the article below which describes some of the problems related to the device. How do I connect a single switch to fan and light when the red and black wire of the ceiling box are already connected to a light switch?
Splice the black and red wire from the fan to the red wire in the ceiling box and keep all the white and ground wires together. Make sure that the black wire in the box is capped off. Once you are done with this, you can operate both the fan and light with the switch. You could also use pull chains to activate the fan and light separately. The light does not turn on as the new switch I have installed is not working. How can I fix this?
It could be happening as most probably, one of the wires in your fuse box could be loosely connected. First ensure that the bundles of black wires are connected to each other with a wire nut. Then check the white wires and tighten the connection. Also you have to check the hot wire in the switch box. If everything seems to be perfect, then the problem could be with the light fixture itself. Call an electrician to help you in this. I am planning to fix a light fixture above the light switch on the steps which controls the light fixed at the bottom of the step with red and black wires and also a black wire runs from the same switch to the floor above. How do I go about the wiring to control both the new light and existing light at the bottom with the same switch?
This might not be possible as the wires in the fuse box are for the switch without a neutral wire for the new light fixture you are planning to install. You have to start a new round of wiring from the existing light that is installed at the bottom of the steps. Can I replace a faulty light switch without turning off the electricity while standing on a wooden floor?
It is always advisable to turn the electricity off before opening a switch plate irrespective of whatever electrical troubleshooting you do. Can I install a timed light switch that has a white (neutral), red (load) and black (hot) wire with white and black wires in my wall?
No, you might not do this as most probably, the white wire on your wall is being used as a hot wire instead of a neutral wire. You can use an Intermatic ST01C which does not need a neutral connection to install the timed light. There are varieties of light switches available in the market like push button, toggle and rocker, etc. A single light switch can also be used for multi-way switching. Few precautions needs to taken to ensure your safety while working on a switch. Turn off the power from the main/master switch before taking the plate cover off using a flat head screwdriver. To remove the switch from the box, loosen the top and bottom of the mount. If you are not confident enough to do it on yourself, you can always ask an electrician to fix the problem for you.
