Richard if you can't find a switch that works there are other options. If the router is strictly used in a table then you can bypass that switch and use an external one which is usually preferable anyway and not particularly expensive. Grizzly sells a few different ones. If it iws to be used handheld then the only other option is a foot pedal switch. For safety purposes it should be a deadman's type pedal. If you lift your foot, as in moving to rout more, the router will automatically shut off which can be a pain but it would still allow use of the router.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
