Exactly, and the additional safety concern too. As others have said, there are already wireless switches, some using battery-free ultrawideband. But even if you prefer wires, it makes no sense to have the actual load-carrying wires routed to the switch - have a separate two-wire switch/control network. Or have it all run on single-pair ethernet - which can carry enough power for lighting too, with PoE/PoDL.
