    The evap system does not us any "switch" that I know of. The evap components are: Canister, Purge Solenoid, Vent Solenoid, and Fuel Tank Pressure Sensor. If you can provide the fault code that triggered the diagnoses of a faulty "switch" perhaps I can help you.

    The evaporative control (EVAP) system captures any raw fuel evaporating from the fuel storage system (e.g. the fuel tank, filler neck, and fuel cap). Under precise operating conditions dictated by engine temperature, speed, and load, the EVAP system purges these captured fuel vapors back into the combustion process.

    and if you can provide the code, may be I can help you.
