Abstract

A temperature sensing switching device has a soft ferrite material coupled radiatively to a body and non-radiatively to a heat sink. The ferrite material is arranged so that its temperature is above its curie point when the body is above a desired limit temperature and below its curie temperature when the body is below this limit temperature. The change is the permeability of the ferrite material moves a magnet which controls the delivery of energy to the body. The switching device may be used to control a stove heater or a burner control system for controlling flow of combustible gas to a burner.
