<p>The closing switch according to the invention has: an element (80) which upon an increase in temperature of the liquid to be monitored exhibits a bellying effect; a plunger (50) bearing against the bellying element, this plunger being loaded in the direction of the deformation produced by the bellying by a calibrated spring (40), and in the other direction by a diaphragm (60) which can be elastically deformed under the action of the pressure exerted by the liquid. In this way, an increase in pressure produces a displacement of the plunger in the sense of reducing the power exerted by it on the bellying element, the bellying temperature being increased. In this way, the permissible temperature increases, before the contact of the switch closes, as a function of the pressure prevailing in the circuit. <IMAGE></p> |
