Abstract
A controlled cycling thermal protector device is provided comprising a snap blade and a PTC resistive heater disposed outside of a bulbous envelope in which the snap blade thermal protector is housed. The snap blade thermal protector and the resistive PTC heater are wired and constructed so as to prevent cycling of the snap blade thermal protector. The PTC heater is disposed upon a sleeve which encircles the bulbous envelope so as to radiate heat onto the snap blade thermal protector to keep it open once the circuit has been broken.
