ABSTRACT:
A thermistor arrangement for the demagnetization of color television picture tubes having a continuous coating or layer at one side thereof which is maintained at a given potential and having two coatings or layers on the other side which are spaced by a width which approximately corresponds to the thickness of the thermistor. The thermistor is connected in a circuit arrangement so that it is divided into first and second zones with one of the zones acting as a heater for the other zone which acts as a switch for the demagnetization coil. The tube conductive coatings or layers which are spaced by a slot may be arranged in various patterns to produce given desired characteristics.
