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
C1 4.7u, 400V
C2 4.7u, 400V
C5 680u, 10V
C7 10u, 50V
CX1 [Not populated]
DB1 Diode bridge
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
LED1 3mm LED
MOV1 VDR, 10D471K
Relay MPE-105-A, 16A, 250VAC, 5V DC coil
S1 microbuttonswitch
?? Ikea Trådfri ZLL module.
Contains all the logic handling.
Identifier Value bottom layer components
C3 [Not populated]
This component was called also C7 but that conflicted with the C7 on layer top.
C4 1.1 uF
C6 [Not populated]
C8 1.1 nF
C9 100 nF
C10 10 uF
C11 [Not populated]
C12 100 nF

Just to mess with your head, I did not rotate this one 😀

      I ordered a LCR meter from China, and it still did not arrive. I planned to measure the components and solder everything back on to measure voltages on the device.

      In the mean time some other project came which grabbed my attention.

      @Oliver, What more would you like to find out about this device?

    One silkscreen identifier is wrong in the table: DB1 is not the relay (which is just labeled “Relay”), but it is the 4 pin component (rectifier? or some off-line voltage converter?)

      Thanks Stefan, I have fixed the error in the page. I hope the LCR is arriving soon so I can complete the rest of the teardown.

    Wow! I can’t figger it out. Hows that power supply working?! Where’s the WiFi!

      The power supply can be found here: L1, C1, MOV1, F1, RL1 the comes the bridge rectifier DB1 companied by C1 and C2 for stabilization and then comes U1 for regulating it to a specific voltage.

      This type of power supply is inherently unsafe to touch on the low voltage side because it still can be at a potential level of 110 to 240 volts!

      The “wifi” is done with a generic Zigbee module. (https://diystuff.nl/tradfri/tradfri-zigbee-light-link-module/) So that is not wifi but Zigbee. Normal Ikea Zigbee modules have ZLL (Zigbee Light Link) but bcos it is not a light, it can be another type of Zigbee protocol.
