Abstract
Proposed is a device for the analog actuation of a digital setting process, specifically the setting and/or calibration of transducers equipped with microprocessors, with a setting shaft extending through the outside wall of a housing in the interior of which the electrical/electronic components of the transducer are located. The device is formed by a first, analog component and a second, digital component which is in nonpositive connection with the first component. The rotary movement of the first component pivots a cam which is firmly connected with it against the paddle of a rocker switch, causing the paddle to deflect. Associated with the deflection, the rocker motion of the rocker switch about the fulcrum causes a boss arranged on the rocker switch to engage the push button of a push-button switch arranged on a printed circuit board, to switch the push-button switch and to close or open a circuit necessary for setting and/or calibration.
