Abstract
A positive temperature coefficient thermistor device includes an insulating casing housing a pair of positive temperature coefficient thermistors. Each of the inner surfaces of a pair of opposed walls consisting of the side walls and the top and bottom walls of the case is provided with a recess formed of at least one pair of tapered surfaces sloping from the walls provided with a pair of electrodes towards a common electrode located in the center. The thermistors are arranged so that the rim thereof has at least a one-point contact with the tapered surfaces of the recesses.
