Another Ikea product gives away its secrets. This time it is the brand new outlet switch. It is brand new and is not even to be found on the Ikea website.
Since the product is only in my possession for only a few days, I only have the PCB reversed. All different components need to be identified by color coding or by just attaching a multimeter.
When applying some heat, friction and ridiculous amounts of time you will get this:
|Identifier||Value top layer components|
|DB1||Relay, MPE-105-A, 16A, 250VAC, 5V DC coil|
|F1||something wrapped in shrinktube, but I don’t think it is a fuse.|
|L1||color coding purple, brown/red, brown/red|
|L2||Burried under shrinktubing|
|??||Ikea Trådfri ZLL module.
Contains all the logic handling.
|Identifier||Value bottom layer components|
This component was called also C7 but that conflicted with the C7 on layer top.

Just to mess with your head, I did not rotate this one 😀
To give some insights on the process have a look at this:
A lot more to come in the next days.
