Distributor ignition contol module switch

I have a 1984 lasabre, 307 engine, 8 cyl, 4 door sedan. Yesterday I changed the plugs, wires, and disdributor and rotor. The clerk at auto zone told me to gap the plugs at 080, however, when I took the old ones out, they were gaped at 060, as were the new plugs I had just bought. So I put the new ones in at 060. So my question is this: would the difference in gap size cause the ignition control switch located in the distributor to go bad? If not, what are some of the reasons a ignition control switch would go bad? And would this cause the car not to start?
