The IKEA Jansjö was amazing 12 years ago, a cheap bright LED lamp when others cost $150. It was $40 (went down to $15 and now may be discontinued). But the switches on them were awful. Both of ours flicker and conk out unless you squeeze or bang the switch just right. I love the final repair step in Fixing flickering Ikea Jansjö lamps : “This POS switch doesn’t deserve UL approval, so remedy that with a Sharpie” 😄
Those instructions explain how to repair the existing switch by opening it up and soldering. That was beyond my skills, so I ordered a quality cord switch, the Leviton 5410-W appliance switch for less than 5 bucks. I don’t own “external snap ring pliers” so I just brute-force dismantled the existing crap IKEA switch. Even then it was hard to pull the wires out. Connecting the Leviton switch to the lamp cable was a breeze in comparison.
