It sounds like (I am speculating) you may have inadvertantly packaged it in such a way that there was pressure on that switch. Sometimes a package can be wrapped up in lots of good wrapping material but there is inadvertantly a weak spot subject to a lot of pressure. Notice that original wrapping of audio gear, by contrast, usually consists of sculpted plastic form, with the weak spots surrounded by foam rather than covered by foam.
UPS is very rough on packages so any pressure point is a source of concern. Like another writer above, I have generally switched to using Fed EX - I love their 3 day COD service. I would only use UPS for large packages and then only if I had original packing material. Not a good situation alas.
As seller I would expect to bear the brunt of the remedy, if not all of it, unless UPS can be clearly held to account. As buyer I would offer to absorb a nominal part of the cost of remedy, such as paying for the second shipping.
