Title: Grant W. Nelson: Innovator in Electric Switch Technology
Introduction
Grant W. Nelson is a notable inventor based in Milwaukee, WI (US), recognized for his contributions to electric switch technology. He holds a total of 4 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
One of his latest inventions is an electric switch designed for switching individual phases of multi-phase AC electric power. This switch features at least one pair of fixed terminals, each equipped with an ear extending upward in a vertical plane. The conducting device within the switch has contacts that extend downward in the vertical plane, aligning with the fixed terminals. Moving contacts are mounted on an axially translatable contact carrier, which engages contemporaneously with the contacts from the conducting device and the fixed terminals when the contact carrier slides into an 'on' position. This design allows electrical power to flow from the line-side fixed terminal, through the conducting device, to the load-side terminal. The contact carrier is translated axially by a drive mechanism that employs over-center shifting and lost-motion switching technology, ensuring the switch cannot be in a partially 'on' position. Additionally, an auxiliary switch can be mounted to operate simultaneously with the electric switch.
