Abstract

527,568. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. April 14, 1939, No. 11439. Convention date, April 14, 1938. [Class 38 (v)] A bimetallic strip 5 bears a contact on its free end, cooperating with a contact on a radial arm 7 borne by an electrode passing through the evacuated casing in such a way that it can be rotated to adjust the initial pressure between the contacts to vary the temperature at which the contacts separate.
