ABSTRACT:
A pressure compensated temperature switch for the protection of an internal combustion engine or the like. The switch unit includes a housing, a portion of which is positioned within a passage in the cooling system of the internal combustion engine. Within the housing is a pressure sensitive member. The pressure sensitive member senses both the temperature and the pressure of the coolant fluid in the coolant system of the internal combustion engine. A visual and/or audible alarm device which is connected to a switch unit of this invention, thus operates when temperature conditions exist within an engine which are harmful to the engine.
