Abstract
A button-operated electronic switch, which includes a button to be operated by the user and a domed element constituted by a piezo-electric plastic sheet. Said sheet has electrically conductive electrodes in the form of a film on both sides, wherein the button is aligned with the dome in such a way that when the button is pressed the dome is distorted, and in the distortion of the dome it generates an electrical impulse between the dome. Film electrodes that provide an output that indicates which button has been pressed. (Machine-translation by Google Translate, not legally binding)
