1,047,598. Thermal switches. DRAKE TRANSFORMERS Ltd. Aug. 16, 1963 [Oct. 1, 1962], No. 37122/62; Heading H2B. [Also in Division G1] A thermal switch comprises a bi-metallic element 2 secured at one of its ends to a baseplate 1 and having an extension 10, on that end, which projects through an aperture 11 in the base-plate to prevent lateral movement of the bi-metallic element. The bi-metallic element may be heated by a current passing through it or by a heating resistance 13 wound around it in which case the heating element is formed of flat tape so as to give a greater radiating surface for a given cross-section than circular wire.
