Bimetal thermostats for precise control applications specifically designed and built with miniaturization and low cost in mind. Each consists essentially of a spring, which has virtually indefinite service life and sharp, distinctive tripping characteristics, and a flat bimetal which is distortion free. Two pieces of bimetal are used in combination to increase sensitivity.
The small differential, sharp snap action spring plays an important role in achieving desirable thermostatic response. This snap spring turns on and off over an exceptionally small distance (approx. 0.05m/m), or in terms of temperature, approx. 3 degrees Beryllium bronze snap spring can withstand at least 2 million operations.
