To me Thyrite is a Stress Tab for electronics.

Anybody know of an available online source for a suitable replacement for this part? It is a thermistor, 79 ohms (cold). thanks
Speaking of switches, the switch in my hair dryer went bad this morning, I could see flames shooting out of it thru the white plastic housing. It finally quit and I finished drying my hair (which now smells like a burned transformer!) and then I unplugged it, ran water thru it and tossed it, time to buy another one!
