Abstract
A main heater controller is adapted to control operation of the LCD heater. A temperature controlled override switch is adapted to disable the LCD heater, independent of the main heater controller, upon a temperature reaching a shut-off temperature above a normal operating temperature of the LCD. The temperature controlled switch has a current flow path made of a material whose conductivity is a function of temperature. A cavity in which the temperature controlled switch is located is also provided. The cavity is adapted to transfer heat in air emanating from the LCD heater to the temperature controlled switch.
