As previously mentioned, plas-t-pair will repair most anything plastic, you can use a small drop to make a new ear, you can drill it or file it, whatever. It's about $10 at electronic supply houses (it's liquid and powder epoxy) for the regular size. You'll find a lot of uses for it once you see what it is. It sets up fast to a very tough plastic, vastly superior to JB weld etc. for certain usages ( like your window switch problem).
