1971 Demon Parking Brake Warning Light Switch

I'm looking for an original working switch for the parking brake warning light that works or if there is an aftermarket switch that will work but I could not find anything in my Googling. The only switches I could find on eBay are attached to the entire assembly and I only need a switch. I wouldn't mind buying the entire assembly just for the switch as long as it wasn't too expensive and the switch was working. The first pic I attached is the empty bracket I think.

Also side question I assume the blue wire in the second pic is what plugs into the switch if I had one?
