The 20-year-old moves to the London Stadium on a four-year deal for a fee understood to be around £5.5m.
Fernandes - the cousin of former Manchester City midfielder and Switzerland international Gelson Fernandes - came through the ranks at Sion and made 26 league appearances for the club last season, in addition to playing in both Europa League matches against Liverpool.
Fernandes becomes West Ham's eighth new signing of the summer.
