Abstract

593,370. Thermal switches. THERMEGA, Ltd., and SINGLETON, S. A. Feb. 20, 1945, No. 4250. [Class 38(v)] A bimetallic switch, which may be of the form described in Specification 587,111, has two heating coils 26, 27 joined in common at one end to a rivet 28, and both evenly distributed along the same length of the bimetal strip 1, and connected to separate leads 31, 32, at the other end, so that whichever coil is in circuit, the heat is applied to the same length of the strip. The windings may be of different resistance alloys or different gauges, so that each winding gives a different heating effect.
