Abstract (en)

The invention relates to a thermostat for adjusting temperature in electric apparatus comprising, inside a box-like body, a membrane, coupled to a liquid holding probe varying its volume as the temperature changes. The thermostat comprises a rocking member supporting a non conductive material pad, affecting a metal blade, depending on the volume variation, in turn depending on the temperature transmitted to the membrane. The blade is driven from a first position, providing an electrical connection between an input terminal and a first output terminal, to a second position, in which the blade is electrically connected to a second output terminal. The blade can be resiliently recovered to the first position thereof by a resilient fork element, the legs of which bear on an insulating diaphragm, provided with a hole for allowing the pad to pass therethrough. <IMAGE>
