Thank you! Too bad guarded switches are hard to replace... I think the one I'm trying to fix is a guarded switch.

Not really any harder than other switches. Tightening the nut on the inside of the hilt can be tricky, but that's the worst part.

Get a long flathead screwdriver and you can use that to manipulate the nut and remove the switch.
