Abstract

A digital pressure sensor of the capacitive type comprises at least a pressure detector unit (36) to detect at least a pressure in an electrical appliance (1 1). The pressure detector unit (36) comprises at least a conductive plate (28) of a printed circuit (27) and a conductive membrane (31) disposed parallel and distanced with respect to each other to define a capacitor with variable capacity due to the effect of said pressure, and pressure measuring means (34) configured to detect variations in capacity and to generate a signal relating to the variations detected. The printed circuit (27) comprises at least a connection portion (127) provided with at least six connection terminals (54) each defining an end of a conductive track (54a), which is connected, at the opposite end, to one and/or the other of the conductive plate (28), a part of the printed circuit (27) other than the connection portion (127), the conductive membrane (31), the pressure measuring means (34).
