Abstract
A thermally sensitive semiconductor switch structure has a nichrome strip vacuum evaporated and sintered in a zigzag pattern on a ceramic substrate and a silicon pellet disposed on the substrate through the nichrome strip and a glass layer. A thyristor is provided in the silicon pellet and is electrically insulated from the nichrome strip. The thyristor is adapted to be heated by a current flowing through the nichrome strip and to be turned on upon its reaching a predetermined temperature. When its temperature decreases below the predetermined magnitude, it is turned off.
