This project replaces the entire control panel under an Ikea Bekant desk. The buttons on my control panel started "sticking" first, then simply stopped working. Stuck in a position I can't really work in. So I disassembled the control panel and figured out the pinout, shorted the connections where the wires would have been and set it to an acceptable height.
Then I ordered a ribbon cable, ribbon cable breakout board, 2 switches and a micro switch (optional). I designed this model to fit the original circuit board, and the breakout board. The original control panel had a hole where a pin goes, the desk can only move when it is inserted, a safety feature for small children I suppose. I preserved the feature by introducing the micro switch into the design. You can leave this out if you don't need it.
NB: The original pin does not fit in the hole, it fits 5mm pin, I used a long bolt.
BOM:
- 2x 16mm momentary normally open switch
- Microswitch 12.8x6mm microswitch, such as Omron D2F-L3-A1, D2F-L3-D3, D2F-01L3-D3, or D2F-01L3-D. Important are the dimensions, the lever and the radius of the lever end. (OPTIONAL)
- FPC/FFC cable 10cm, 1mm pitch, 10Pin (eg. https://www.aliexpress.com/item/10000012558629.html )
- FPC/FFC breakout board 1mm to 2.54mm pitch (e.g. https://www.aliexpress.com/item/1005003044150117.html )
Wiring:
| Pin | Connect to |
| 5 | NO on switch 1 |
| 6 | NO on switch 2 |
| 7 | NO on micro switch |
| COM micro switch | COM switch 1 |
| COM switch 1 | COM switch 2 |
If you don't want to use the micro switch, connect 7 to COM on switch 1 directly.
Disclaimer
I will not take any responsibility for any type of damage caused following these instructions. That said, this fixed my desk, and I believe anyone should be able to repair their things so they don't have to buy a them new, especially for such a small defect, and especially if we want to keep living on this planet.
