A temperature detect switch made up from InSb-In eutectic film magnetor resistor(MRGS)is introduced.The temperature detect switch including a magneticresistor and a single processing circuit has a high sensitivity and a wide temperature control range.The experience proves that its sensitivity can reach more than 30mV/℃ in low temperature and more than 23mV/℃ in normal temperature.The range of adjusted temperature is-40~120℃.The measurement accuracy can reach ±0.1℃.
