ABSTRACT:
In an arrangement for converting the pressure of a pressure medium into an electrical signal, there is provided an electrical sensor 1, which is presently positionable into one of two fixed positions by a reciprocable adjusting element 3 through the alternating pressure of the pressure medium, under the concurrent electrical connection and disconnection of its contacts 4, 5. In order to maintain the constructional volume of the arrangement as well as the requirement of components as small as possible, the contacts 4, 5 of the sensor 1 are directly electrically connectible in one of the two fixed positions of the adjusting element 3.
