Typical American Made product.
This was packaged well in a heavy duty box with extra internal support. It had comprehensive and well written and easy to understand instructions. This was a replacement, but the instructions we good enough to help someone add this switch to a new installation/design. The entire part was well made with excellent fit and finish. I installed it, it worked the first time and I haven't had to think about it since. Buy American!
