Abstract: A device for rapidly defrosting a refrigerator compartment, such as a freezer compartment or the like, said compartment comprising a plurality of adjacent walls, in correspondence with at least one of said walls there being arranged a hairpin coil evaporator for a static refrigerator, or a part of an evaporator of forced-air type, within a refrigeration circuit comprising a motor-compressor unit, said device comprising heating means arranged in correspondence with at least one of said walls and/or with the evaporator, said heating means being electrically powered via an electrical supply circuit associated with the refrigerator; the heating means are at least one resistance element of PTF (polymer thin/thick film) type.

Abstract: A door switch assembly for a refrigerator. The door switch assembly includes a housing mounted to one of the walls of the refrigerator and further has an electrical circuit for switching on or off electrical equipment mounted within the refrigerator. The door switch includes a ball retractably mounted in the housing and biased to project partially outward from the at least one wall for engagement with the door. A pusher is slidably mounted adjacent the ball and biased to remain in contact with the ball. A flexible strip contact element is supported within the housing which is moved by the pusher in such a way as to open or close the electrical circuit. The housing includes a projecting portion which extends through an opening provided in the at least one wall, the projection portion includes a deformable flange.
