ABSTRACT:
A positive temperature coefficient thermistor device comprises a pair of positive temperature coefficient thermistor elements, a common terminal plate having a heat conducting terminal member and a common terminal member and being sandwiched between the positive temperature coefficient thermistor elements, and a pair of terminal plates having spring terminal members for clamping the positive temperature coefficient thermistor elements. The common terminal member of the common terminal plate is formed to have a width between the heat conducting terminal member and an insertion hole in the mounting plate on which the positive temperature coefficient thermistor device is to be mounted that is no larger than necessary for its insertion in the insertion hole. A catch is provided on the heat conducting terminal member for engaging with a wall of the insulating case for preventing extraction of the common terminal plate from the insulating case.
