Abstract

671,163. Thermal switches. PERMA SOC. ANON. March 20, 1950. [March 23, 1949] No. 6844/50. Class 38 (v). A thermal switch for controlling the temperature of an electric heater 2, comprises a frame 1 with a pin 5 on which are freely pivoted a bimetallic strip 3 and a metal supporting member 6, the latter supporting flexible blade. contact carrying members 8, 9. As the temperature of the heater rises, the blade 3 deforms, its middle portion coming into contact with the heater 2 and its free end lifting a push piece 12 secured to the blade 9, so as to raise the free end of the blade 9 to open the contacts 11. An adjusting screw 18 carried by the frame 1, has a tip which engages the end of the member 6 to determine the extent to which the bimetallic strip must deform to cause opening of the contacts.
