Abstract (en)
[origin: EP0201680A2] A thermostatic switch has a circular, concave or convex curved bimetallic disc, which is supported with its edge on a housing part and whose central region acts directly or indirectly on a contact tongue. In its central region, the bimetallic disc deviates from its radius of curvature, and in particular this results in a contrary concave or convex curvature with a smaller radius of curvature. By means of this special forming, jumping back is prevented if the temperature is lower than the resetting temperature, this no longer being desired for particular applications. As a result of this property, the thermostatic switch is to be reset to its original state again exclusively by external mechanical influence, while the forming according to the invention has no adverse effect on the correct operation of the bimetallic disc on reaching the switching temperature. <IMAGE>
