  • Patent number: 8599034
    Abstract: A switch, particularly a switching device or operating device, includes a flat display, wherein the flat display is provided for the visual display of at least one item of information related to a current or future condition of the switch or a system or machine associated with the switch. A more effective spatial arrangement of the switch components, and reduced energy consumption, is accomplished by a flat display of the switch of at least one embodiment, at least partially including an electrochromic material and electrodes. The electrodes are provided to supply particular regions of the electrochromic material with an electrical voltage, in order to thus activate a color change, and to provide one or more items of information to the use by means of an intelligent control.
