Umm can't see anything joining the screws on either the old switch or the new. That area is covered by a shield (box) that is riveted in place, so can't see between the screws. The only thing sticking out are the screws themselves. ( I know what you mean though about the link between the screws, we just can't get to it without tearing up the switch.)
P.S. Thanks for the welcome. Finding so many interesting things. Hubby may be sorry after I tell him all the diy stuff I'm finding.
