This electronic meter signalling device provides a means for converting a conventional meter or gauge into an electronic switch in which a number of electronic outputs indicative of conditions of the meter or gauge are provided. The meter signalling device comprises a capacitive coupling means used in conjunction with an indicator of the meter or gauge to form electric charge coupling paths at a number of predetermined scale conditions of the instrument. Electronic circuitry transmits a signal through each electric charge coupling path to a discriminating circuit to activate outputs indicative of the scale conditions of the instrument.
