  • Electric switch, especially a piezo switch, with optical and/or mechanical feedback of the switching operation
    Patent number: 7250708
    Abstract: The invention relates to an electric switch, especially a piezo switch, with optical and/or mechanical feedback of the switching operation. The switch contains at least one switching element, especially beneath a cover panel, which can be activated by means of an activating element. This causes a switching signal to be generated and guided out via electrical contacts. The activating element itself is configured in the form of a passive luminous body consisting of an at least translucent material, which can be illuminated by active luminous means. The mechanical feedback of the switching operation can take place using a vibrator which is activated by the switching operation that has been initiated and conveys a vibrating motion to the luminous body.
