<p>A method to produce an electronic measuring, conditioning and regulating instrument provided with at least a display front-piece (11), with one or more keys (14) and with an electronic card (20), comprising a step of preparing the electronic card (20) in which at least one or more light emission devices (21) and electric components comprising one or more conductive platens (24) are prepared on a surface of a PCB (129b), and a step of positioning the PCB (129b) associated with the front-piece (11) and substantially parallel and in proximity to the latter. The method also comprises a simultaneous production step of main bodies (32) of the keys (14), an optical screening element (22) of the light emitted by the light emission devices (21), a perimeter sealing element (25) associated with an external perimeter edge of the front-piece (11), by means of simultaneous overmolding or over-injection on the front-piece (11) of said components.</p> |
