Cover plate to place over light switch. Tradfri switch mount-plate can be twist-lock-mounted on it so you can use the App-controlled lights without any physical or electrical changes to existing wiring and light switches.

Any way up you print this it will need supports.

I have the best results printing with legs up, supports on build plate only.

Also included is a cover for a dimmer/switch I have that should not be dimmed or turned off while Tradfri lighting is in use.

I created these for myself, so don't feel bad if you can't use them as is. I am prepared to make alterations on request :)
