Zusammenfassung:	A self-regulating heater assembly comprises a positive temperature coefficient (PTC) heating element and a pair of spaced electrodes. Each electrode includes a first surface. The first surfaces of the pair of electrodes are spaced from one another. The PTC element is located between and supported by the first surfaces of the pair of electrodes and is energized by the pair of electrodes. Means for limiting a compressive force on the PTC element is provided. The means includes an electrically insulative spacer member positioned between the first surfaces of the pair of electrodes. A first pair of power leads, one power lead being connected to each of the pair of electrodes, energizes the pair of electrodes.
