Abstract
347,073. Thermal switches. FELTEN & GUILLEAUME CARLSWERK AKT.- GES., Mulheim, Cologne, Germany. July 25, 1930, No. 22460. Convention date, Aug. 19, 1929. Drawings to Specification. [Class 38 (v).] In a thermal switch a resistance having a low temperature co-efficient of resistance is placed in parallel with a bimetallic strip to increase the time-lag.
