Abstract

Digital scale for domestic use, comprising a housing in which the mechanism transmitting the weighing is housed, and an electronic circuit in charge of activating a digital indicator, according to the signal received from the transmitting mechanism, characterized in that said the transmitting mechanism comprises an armature constituted by two independent rigid U-shaped profiles, parallel and facing, related to each other by two parallel elastic sheets, of steel nature, fixed externally to the facing wings of the profiles, one of said profiles being fixed to the frame of the balance housing, while in the other profile the balance plate support is fixed, so that the action of the weighing acts in a direction perpendicular to said plates, causing its elastic deformation and with it the displacement of the second profile internally fixed in the soul a support of an electrically insulating nature, each of which is an electrically conductive plate is fixed, the two plates being equal and running parallel to each other in a slightly separated position, also carrying the profile mounted on the frame of the housing, an external plate, of conductive nature, which runs parallel and close to one of the aforementioned elastic plates, arranging this external plate and the two intermediate plates fixed to the insulating supports, of pins for the connection to the electronic circuit, acting as a set of conductive capacitor plates, whose capacity varies when the distance between such plates, activating the electronic circuit and with it the digital indicator.
