Abstract
A remotely controlled actuator assembly is provided to switch a large power distribution switch used in an electrical utility power grid. The actuator of the assembly throws the switch between at least two positions to establish at least two power routing conditions. The actuator assembly includes a position-sensing device to repeatably and accurately indicate the position of the actuator. The position-sensing device generates a signal indicative of the extent of displacement of the actuator. The generated signal provides feed-back to a control system which control the extent of actuator travel.
