In the fourth of our tutorials, we’ll learn how to connect a switch for a bedside lamp. After the first three episodes, this last one will complete the process of creating a table lamp that’s both beautiful and functional!
First, let’s clarify that the switch used is an in-line lamp switch, which you can find in our online store. For completeness, we chose to show a switch that also accommodates the ground cord, but the procedure can be applied with only minor differences to classic double-pole switches: just skip the step where it describes where to place the ground cord!
Before you start wiring the switch, we always recommend disconnecting power from the system you’ll be working on.
Let's start by opening the "shell" of the switch by unscrewing the two outer screws, then loosening the screws of the two internal strain relief clamps, whose job is to ensure the integrity of the system in case the cord is pulled.
Once this is done, loosen the terminals that will hold the actual electrical cords, which have already been stripped of their insulation as we covered previously. In this particular case, the grounding cord, always green and yellow, will have its slot along the side of the switch, while the two phase cords will remain inside, on either side of the button. After exposing the copper filament of each cord, it should be placed deep enough into its respective terminal so that the rubber insulation touches the edge of the terminal itself.
Once all the copper filaments of the electrical wire have been inserted into their respective internal terminals, tighten all the screws securely, and then reposition the two strain reliefs so they rest, as shown in the tutorial for wiring the plug, on a section of cord that hasn’t been stripped yet, for 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 outer screws. Our switch is ready, and so is our bedside lamp!
All clear and good to go? Did you make it through without any hiccups, or do you need a hand? Share your experiences in the comments, and as always, let us know which tutorials you’d like to see in the future!
