Abstract: Pressure sensor for measuring the level of a liquid in an appliance such as a washing machine, a dishwasher or the like, including a casing having a cavity, a deformable membrane having an outer edge fixed to the casing so as to divide the cavity of the casing in a first chamber and in a second chamber, and in wherein the membrane is susceptible to deformation as a function of the pressure difference in said chambers, and a detector device located in the first chamber and adapted to provide an electrical signal indicative of the deformation of the membrane, wherein the housing incorporates an air trap including a cup surrounding said second chamber, a tubular portion intended to be connected directly to a tank adapted to contain a liquid, and a barrier forming a siphon between said tubular portion and said second chamber.

Abstract: A position transducer of water level in a machine basin, preferably in a drum-type washing machine or a dishwasher and the like, transforms information relating to the water level in the flood basin of the machine into an electric signal to activate an execution organ. The circuit realizing the transformation is an embedded contact lamella provided with electronic members. Integrally with the step of embedding, a snap arrangement is prepared for engaging and retaining a connector connected to the circuit.
