The claim that it was patents that prevented it from seeing widespread use doesn’t seem legitimate, especially as the list of cons doesn’t mention the high production and component costs of such a mechanism. The reason why crappy dome switches won out despite their really long list of cons is extreme price superiority. The linked design is simply far too expensive and complicated by comparison.

dome switches are definitely cheaper, but i was comparing this design to mechanical switches. the magnetic switch has far fewer moving parts and the tolerances don't have to be very tight.
