ABSTRACT:
The measuring, adjusting and displaying instrument is of the type comprising a front panel and a pair of printed circuit cards, effective to be inserted into a box, said front panel comprising supporting and guiding means effective to support and guide said cards, and through openings provided for receiving driving and displaying elements. The two printed circuit cards or boards have the driving and displaying elements fixed at 90.degree. with respect to the card plane on the front end portion thereof, being bent parallely to said plane in such a position that, upon having inserted the cards into the supporting and guiding means of the front panel, said driving and displaying elements are effective to automatically insert into the provided openings, thereby being visible and accessible by the operator.
On the front panel there are provided means for slidingly applying a handle for withdrawing the instrument from its box, in such a way that the handle can be brought to a retracted position as it is not used.
The through openings provided for receiving the driving and displaying elements are so arranged and shaped as to permit said elements to be located both horizontally and vertically.
