In the fourth of our tutorials, we’ll learn how to connect a bedside lamp switch. After the first three episodes, this final one will effectively complete the creation of what is, in every respect, a beautiful and functional table lamp!
First of all, let’s specify that the switch used is an in-line switch for table lamps, which you can find on our online store. For completeness, we have chosen to show a switch that also accommodates the earth cable, but the procedure can be applied with only minor differences to classic double-pole switches too: simply ignore the step describing where to fit the earth cable!
Before you start wiring the switch, as always we recommend disconnecting the power to the system you’ll be working on.
So, let’s start by opening the switch “shell” by unscrewing the two outer screws, then loosen the screws on the two internal cable clamps, whose job is to ensure the system holds together if the cable is pulled.
Once this is done, loosen the terminals that will hold the actual electrical wires, which have already been stripped of their sheaths as we saw previously. In this particular case, the earth cable, always green and yellow, will have its slot along the side of the switch, while the two phase cables will remain inside, on either side of the button. After exposing the copper filament of each cable, it should be placed into its respective terminal, deep enough so that the rubber sheath touches the edge of the terminal itself.
Once all the copper wires of the electric cables have been inserted into their respective internal terminals, tighten all the screws firmly, then reposition the two cable clamps so they rest, as shown in the tutorial for wiring the plug, on a section of cable that is still insulated. This will provide better grip and greater safety.
At this point, all that’s left is to close the switch casing, repositioning the two parts and tightening the external screws. Our switch is ready, as is our bedside lamp!
All clear and sorted? Did you manage without any hiccups or do you need a hand? Share your experiences in the comments, and, as always, let us know which tutorial you’d like to see next!
