Yeah John, as far as you can safely spread them, that way you can get that little red tubing nozzle right down into the switches... I usually put a few towels under the handlebars just to prevent spraying all the bike plastic with the cleaner...
I had a couple stubborn one's on my buddies 93 Aspy trike a few days ago but I finally got them working... Heating the switches a bit would help too as I suspect the reason they are sticking is that all the lubricant inside the switch has turned into a thick goo... Heating it up should help to thin it out a bit - just be careful not to melt anything with the heat gun or hair dryer...
