I had no idea that there wasn't a pull cord on it and the item description didn't mention it.
It didn't mention Swarovski crystals either.
There's a reason for that - products tend not to have features not mentioned in the description.
Regarding the 230V switch, I'm not sure which one it is to replace it.
You can measure the size of the existing one.
You can compare the dimensions of ones you look at with the dimensions of the one you have.
Nobody here can tell you what switch to buy because nobody here can see the existing one in real life.
Don't take this the wrong way but I'm beginning to think you don't have a DIY bone in your body....
