Abstract
Trip devices are disclosed for attachment to existing utility meters to detect revolutions of a dial arm of the meter. Two embodiments are disclosed, each including a spring-biased shaft extending through a base and a shoe on the end of the shaft. As the dial arm rotates, it catches and deflects the shoe, thus rotating the shaft. The shoe then slips off of the dial arm and returns to its original position under the urging of the spring. In one embodiment, shaft rotation is detected using a magnet and reed switch arrangement. In the other a mercury switch is instead used.
