I use temperature dependent protective devices using metal loaded wax which opens the circuit when the unit gets hot I think IIRC 'Digi-Key' corp. stocks them in a wide range of values both current and voltage. They are not actually thermisters exactly in operation or function. They are common in toasters and hair dryers also. the catalog is on line as www.digikey.com/passives
