Annapurna electronics manufactures thermostats in collaboration with westinghouse, germany and shin- han, korea. These thermostats are compact and sleek with accurate calibration. These thermostats are highly accurate and have noiseless performance. The hinged capillary tube avoids breakages. Contacts are totally enclosed. The switching action is accomplished by a precision snap-action mechanism operating a contact and leaf assembly with bare minimum bounce time to improve the performance of compressor motors and other electrical functions.
