ABSTRACT:
A thermally responsive switch used in enclosed motor-compressors includes a supporter formed of a single metallic plate and including a support arm cantilever mounting a thermally responsive bimetallic or trimetallic element carrying a movable contact at one end, first and second beams disposed in a relation that the support arm is interposed between these beams, and an operative temperature calibration strip integrally extended from the first beam. The calibration strip is slidably inserted between the support arm and the second beam into a wedge structure in the state that the calibration strip is bent at the root portion. Consequently, when the calibration strip is bent with the slidable movement, the support arm is bent so that the contact pressure between the contacts is set, an amount of bending deformation of the support arm corresponding to an amount of bending deformation of the calibration strip.
