(54) Control thermostat for apparatus operating by thermal cycles


(57) The present invention relates to a control thermostat for apparatus operating by thermal cycles.
The thermostat comprises a box-like casing housing therein an expansible plenum chamber which is coupled, through a capillary element, to an expanding liquid holding probe.
The plenum chamber, in particular, is arranged between an adjusting abutment element and a swinging lever operating on a resilient blade, made of an electrically conductive material, coupled to a first electric terminal and provided with a movable electric contact, which can be displaced by the movement of the resilient blade caused by the swinging lever, in order to close and/or open an electric circuit.
