Working on renovations, and got three wall switches like this one in the house - what if any country/standard are they from?
Been asking a few mates but they are all mechanics and fabricators and have no clue.
Wanting to swap all switches in the place with touch switches and smart switches.
Hole in wall is about 90x90, faceplate is 115x110, and screw holes are 46 horizontal across and 85 vertical
Thanks
