Abstract

1,159,437. Thermal switches; movable magnet switches. HERON ELECTRICAL DEVICES Ltd. 10 Oct., 1966 [15 Oct., 1965; 15 Feb., 19661] Nos. 43923/65 and 6495/66. Heading H1N. A temperature responsive switch comprises a container 32, Fig. 3, for a solidifiable liquid 18 which when melted releases a permanent magnet 33 to actuate contacts 24. The switch is particularly applied to operate a warning device in a refrigerator when a maximum temperature is reached. Suitable liquids referred to are water, glycol, benzine and paraffin wax.
