Sorry, no idea about the switches. If all else fails however, having a supplier in the "wrong" country may still be better than nothing as you can arrange the shipment via a forwarding service. That's a company that lets you have a postal address in the country you need (basically their warehouse address + your name and some kind of ID number appended), receives the packages for you, and forwards the packages received to your real address overseas for a fee.
Forwarding companies are popular especially in countries with high-ish language and cultural barriers, like Japan, and allow foreign customers to pretend to sellers to have a local address, avoiding lots of "NO"s because of the sellers' unpreparedness to fill out customs documents in other languages and things like that. Usually such services charge a "per package" fee in addition to the shipping costs, but no fees for registration and no recurring fees just for "having the address".
The USA also seems to have their fair share of such companies, but since I have never used any of the US ones, no idea as to their reliability or trustworthiness. As always, buyer beware.
