Has the clutch cover ever been removed on this bike? If so, it is easy to crack the water pump driven gear (plastic on 2000+ SV650) if not aligned properly during reassembly.

I agree with Svracer2, it is not the thermo switch, something is preventing coolant flow. Check low coolant, thermostat, blocked passage, or broken water pump/gear.
