In an input device, a control element is operated by a user; a pressure sensor is mechanically coupled to the control element and is provided with a monolithic body of semiconductor material housing a first sensitive element, which detects an actuation of the control element; a supporting element is connected to the pressure sensor; and connection elements electrically connect the monolithic body to the supporting element without interposition of a package. In particular, the monolithic body has electrical-contact areas carried by one main surface thereof, and the printed circuit board has conductive regions carried by a main face thereof; the connection elements are conductive bumps and electrically connect the electrical-contact areas to the conductive regions.
