ABSTRACT:
A contact lens disinfector utilizes a positive temperature coefficient (PTC) element as its heating source. The PTC heater element is held in intimate contact with a heat sink by a spring biasing member which accurately positions and tensions the PTC heater element thereby insuring that sufficient heat is delivered to the carrying case so that proper disinfecting of the contact lenses takes place.
