Electrically that should work fine, and cheap enough to replace yearly if and when it gives up. I could not make out a HP rating for the switch in the pic. I made a comment previously of the uniqueness of compressor start loads. To be clear, most "motors" do not start under full load. Some compressors have an unloading circuit on start up, that helps. Saws, fans, heaters, lights, etc do not have a huge start up current draw like a compressor does. Hard to believe this is same quality as a the Hubble stuff is, and of course it has to be made in China. And start up peak short term currents can easily be over double that of name plate ratings. So I'm slightly skeptical, but can't point to anything obviously wrong with this choice, based on what we know so far.
