check your wiring before getting a new switch. My turn signals went out, I orderd a new swtich and before I could get it in I notice what looked like a relay hanging down in my drivers side fenderwell and it had some chewed up wires. I fixed up the wires, replaced the fuse and they worked again. Do your reverse lights work? If they dont then the fuse is blown...I'm sure you've checked that already but it sometimes gets overlooked. But if the switch is the problem I have a spare one I'd sell cheap.
