Abstract (en)
Refrigeration apparatus comprising one or more refrigerating circuits containing inflammable gases and consisting of at least a compressor, a condenser, one or more evaporators associated to at least a food storage compartment, said compartment accomodating at least an electrical switch that is accessible by the atmosphere of said compartment, wherein the electrical contacts of said switch are enclosed in an air-tight enclosure (6), said switch consisting of at least a pair of ferromagnetic metal blades (1, 2) enclosed in said enclosure (6) and adapted to establish a contact with and separate from each other. Externally with respect to said enclosure (6) there is arranged a moving member (8) which is constrained into moving into definite positions by an appropriate guiding provision (9) and is associated with a magnetic element (7) adapted to act on the mutual position of said blades which move into a contact position or a separation position according to the position of said moving member. <IMAGE>
