Abstract
An analogue position transducer, usable for example as a pressure switch in a household appliance, includes a rigid casing accommodating a deformable membrane sensitive to hydraulic pressure, a first element engaged to the membrane so as to be mobile along with at least one portion of membrane in a predetermined direction (A), and a second element fixed to the casing and operatively coupled with the first element to provide a signal variable according to the relative position of the first element with respect to the second element. Between the first element and a portion of the membrane, an element is interposed for varying, along the predetermined direction, the relative position of the first element with respect to the portion of the membrane. The transducer also includes a spring fitted and preloaded between the casing and the membrane, and a further element for adjusting the preload of the spring.
