I've seen the transfer type, I even bought some for testing from the guy on ebay (absolutely condescending prick), but decided not to bother as the replacement switch covers are now available.
So I made a video on those instead....
Loads available on Aliexpress (same as the more expensive ones on ebay) and far better than a transfer that you then have to varnish or some sticker that's going to rub clear very quickly.
Hope that helps![]()
