i wanted to mount the ikea home smart (tradfri) on / off switch & dimmer next to my normal light switch. In this way i can still use the regular on off switch or control it using the ikea switch. I have to sets of lights in my livingroom. I replaced the cover of the regular switch with a version for 3 outlets. this adapter fits in the cover. The orginal ikea metal mount is put inside the adapter so the magnet in the switch still works. And you can remove the switch from the frame.
The adapter is used in a praxis ottowa series frame. This is a hardware store in the Netherlands.
settings dont really matter. The fit inside the frame is tight.
