How to Replace a Light Switch
Replacing a light switch does not have to be a chore. Replacing a light switch is quick (can be done in a matter of a few minutes) and is relatively easy. However, as with any other electrical DIY, do not forget the risk- safety is your first concern.
Firstly, you must make sure that the power to the switch is turned off at either the fuse box, or the main circuit breaker. If you are unsure, you can always check to see if the power is off, by flipping the switch and noting whether the light comes on. You should always right a note and place in on the circuit box, or alternatively make sure that everyone who may come in contact knows not to turn the switch back on.
Now, you must remove the cover plate. Simply do this by unscrewing the two screws holding the plate in place. Remove the two mounting screws holding the switch in place inside the electrical box. You must then pull the switch out of the wall. The switch should come loose a few inches exposing the wires.
Remove the screws which hold the two wires coming out of the wall to the switch, making sure you make note of which wire came from which screw (they are usually colour coded) you could do this with coloured pens and tape.
You must then visit a hardware shop and purchase another switch exactly like the previous one. There is no shame in asking the shop assistant for help if it is needed.
Hold your new switch up to the wall, right side up, so that the word ‘off’ appears when the switch is in the off position. Then attach the wires to the screws on the switch’s back matching the wires up to the correct screws (according to the tags you have previously made.)Secure the new switch in the box with mounting screws and replace the switch cover.
You can then turn the main power back on and test your work.
