The ignition switch needs to be replaced to be sure it's not related. But I think it's more likely the battery/starter motor or connection's is the fault.
STARTER CRANKS SLOWLY
Ensure battery is fully charged and cables are clean and properly connected. Check for short to ground. If problem still exists, clean and tighten connections at starter relay and battery ground connection on engine. If problem continues, replace starter.
