<p>A magneto-thermic switch having thermal protection which can be calibrated mechanically, in which the casing (50) is provided with an opening (25) for detecting, with a sensor (33) introduced into the opening (25), the rest position (with respect to the casing) of the free end of a bimetallic element (10) which actuates the thermal protection, fitted on an adjustable cantilever support (9,67) thus allowing the cantilever support (9,67) to be adjusted to make the free end of the bimetallic element (10) assume a predetermined rest position with respect to the casing (50). <IMAGE></p> |
