Abstract
In a cooking and heating apparatus, a device for warning personnel of dangerously hot temperature is incorporated within the structure of a thermostat which has a switch for regulating the flow of electric current to a heating element of the apparatus. The thermostat includes a push rod mechanically coupled to a finger-like termination which extends through an aperture in an arm of the regulating switch to engage the arm of a further switch used in activating a warning indication. A collar on the termination engages the arm of the regulating switch subsequent to the activation of the further switch by the rod. The rod expands with increasing temperature and, thereby, initiates the warning at a lower temperature than the temperature of the power cut off by the regulating switch.
