Electronic control device () comprising: —an electronic circuit () having an operative face () on which a plurality of LEDs () are mounted; —a frame () defining a plurality of first channels () which face the LEDs so as to guide their light radiation; —a composite screen () which covers the first channels () so as to be crossed by a light radiation coming from the LEDs () and guided by the first channels () towards the composite screen (). The composite screen () comprises:—a diffuser layer () configured to homogenize a light radiation that crosses it;—an operative layer () having electronic tracks comprising touch-sensitive pads () and connection contacts (). The electronic control device () further comprises at least one connector () which connects electrically the connection contacts () to the electronic circuit () in order to transmit to the latter electrical signals following touching, by a user, of at least one of said sensitive pads () on the composite screen ().

Electronic control device

Described is an interface () for a control device having a front face () and a rear face () and comprising a plurality of layers grouped in a covering assembly () and a tactile assembly () extending between the front face () and the rear face (); The covering assembly () comprises, in sequence: —a protective layer () having the front face (); —a masking layer () which directly or indirectly covers a second face of the protective layer (). The said tactile assembly () comprises—an operative layer () with sensitive pads () reactive to touch and permeable to light, transparent or perforated; —a matrix layer (), opaque and equipped with shaped portions () which are either permeable to light or transparent or perforated and aligned with the sensitive pads (). The sensitive pads () and/or the shaped portions () are configured to form signs (B) designed to generate luminous symbols visible after backlighting of the interface (). The masking layer () has a permeability to light such that the signs (B) are not visible through said masking layer () when said front face () is illuminated by a light radiation resulting in a luminance not exceeding 4000 lx and the interface () is not backlit.

Control device interface, especially for vending machines and displays

The disclosure provides a control device which can be installed within a cold room, and within a refrigerated or air-conditioned environment in general, without the electronics for managing the various components becoming damaged. The disclosed device is easy to install and/or retrofit and requires no burdensome wiring, ducts, cables and connections.
